Blind Spot Monitor System Malfunction In Lexus es350 || Wrining Diagram + Solution 💯

Now I have removed its grip also, it gives the output of light. Now I have removed its grip also, but still you will see that the light is on in our vehicle . It is off but our light is on, so this is the problem, see the input from here, it is completely off. Yes, Assalam Walikum, I hope that all of you friends will be fine and tell all your friends who are not coming to my channel. Fault Code with Hamza I welcome you, this is the car you are seeing, I have it 350 2000 16 model, this is the car

, there is a problem in the car, yes, I will check it for you a little, this is the mirror you are seeing, its the driver. Right now the car has started, there is no problem in the car, there is no error, you are seeing that this is the wind fluid only error is coming in it, one more thing, there is no error in it, now I will get you checked one thing, see, I will stop this car. I have switched off the car and in its wind mirror, you can see that the BSM light is on and the BS automatic light is

coming on. When the car is switched off and the car is completely locked, its light is still on. It remains on. It is not in that mirror. It is not in the right mirror. Only and only the one which is there is in the left mirror. Its automatic light comes on. So, look at this. When I start the car, it has turned off, but it is bound to happen. It should be like this that when I switch on and start the car then the BSM light should come on in both its mirrors but the BM light does not come on at

that time. When I switch it off then the light comes on. So this is it. I have diagnosed it using the tool scan tool on my scanner. This is the launch pad. Many friends often ask later in the comments, so I tell you in advance, so this is BSM. This is what you see: Slab Blind. Spurt Monitor , this is its second master master, this is the slip and this is the masters, there is no DTC in both, now there is no code in both BSA, you will be seeing these two, this is the state ability mal function in

its engine and this is our error in BCM. Remote starter ACU communication staff is coming , this is also in body control module and an error is coming in navigation but this error is of voice recognition and microphone disconnected so this is also not related to our fault, it should have been our fault. Let me check these two errors again for you. See, I will diagnose it again from here. If you see that our error is not coming in the BSM which is ours, then how to check it, I will also tell you

step wise and Inshallah this fault. Let's clear whatever is coming and first of all, this diagnosis is also being made, I am showing it again so that I have not cleared any error etc. You thought that maybe I have cleared some error, but no error has been cleared in this. No, this is not automatic, see, if there is no fault in BSA, then see this, it is absolutely clear here, yes, I have taken out its wiring in the system, you are seeing Lex 350, this is going to G Clues Advance and Parking Assi

st. Now all the functions of our advanced parking assist or edge have come in it, see this, see Lane Departure Parking Assist and please, what we have is a smart monitor system, I am opening it and we have to see what our The light comes from the driver's side mirror, where does it come from, the driver master that is connected to it, the radar behind it, or the computer that it has, it is coming from there, so right now it is getting a little loaded, it is loaded. Yes, this is what you are seei

ng: blind spot monitor sensor right hand. This is right hand. And this is the outer mirror control ECU assembly. This is going to go to this. Yes, this is the outer rear mirror. This is from the right side. We have taken our left side. We have to check this, see the blind spot monitor sensor on the left side, which is ours in the RG light. Blind spot monitor main switch, warning canceling switch, overall, this is our switch which is installed, there is no problem in it, we have to check our ligh

t from here. If I take the wiring further, then yes, this is our light, this light has come, behind our left side, its sensor is installed for the radar, there is a wire coming from there, this wire, you are seeing these are of two cans. Wires are going into this, see in this radar, one, two, three, one, four, these are the number four wires, you will see these four numbers, from there, this violet colored one is coming out, ahead is another connector, through here, it is going into another conn

ector. and again another connector Going inside and then coming this way, see how many connectors are there. In all the wiring, it is coming here through one, two, three, three connectors. This is our outer mirror control ECU assembly. This is the left hand side ECU assembly, which is inside the mirror. Our light is connected from there, it is coming on, so this is its ground and this is our light, it is coming from it, see number 13, this is the wire which is coming from the mirror, our sorry,

the problem with this is its sensor. It is coming from the left side and the one which is our ground is number seven and in this 12 and eight two wires are going to our blind spot monitor which is in the outer rear in which our light is on. If this light is on then our We have to check what is ours and for what reason is it giving us direct current here and there, then the problem is coming in this ECU of ours because there is no error etc. if the error is of its light then it comes on at the sa

me time. See , this is not our error, that is, there is no problem with the blind spark sensor in the wiring, so we have to check this, this is our circuit which is coming from here, we have to check, see, this is the number four wire. It is going to number 13 and the number is I, you will see ground, this is ground, you are seeing that three lines or four are coming, then 9 is written, this is A grip and this z7 is B grip, now see. The wire that is coming is number 13, it is written as A, isn't

it? This number 13 is going to the A grip and if you look at the ground, it is number seven in the A grip and the light that is coming out here is our output, it is going to ours. B, you are seeing bp1 number and b8 number, see m9 and z7, A and B are two grips and where will you get them. If you are using all data etc. then you will definitely come to it, then the details of its wiring are written below. These are the details of the grips, so see, this is m9, this is our m9 grip, it is correct,

now in this, above us, there is also another grip which I made you check. z7 Yes, let me show you so that there is no confusion later. Yes, see z7, this is also in white color, it is also written above which color is this, this is white color, so pay a little attention, do not skip the video, because in the series of videos that I am bringing, everything is also there in the wiring diagram. This is something, so I try in every video that if you understand it properly, if you skip it then you wi

ll not be able to understand it again and again the same questions which I have cleared in the video, so now yes now my Let's go ahead and tell you one more thing about this, see here I have opened this blind spot, so the location is coming here, component location, from here I will do OK, then you will see that you want the location of the parts of the blind spot monitor or do you want parking assist. Or if you want whatever advanced features it has, then I open this blind spot in it, then the

information that I am showing you in the blind spot, this is the location of the part, these are the outer ones which are seeing its light. The rear view mirror assembly is of left hand side and this is its outer mirror control ECU assembly. Check where the ECU assembly is fitted. It is showing the other side. It is fitted on this side, so we will have to try to open it. If you look below it, then this is its See the outer mirror indicator is right and if it is left then it is connected to its b

lind spot. You will see that this blind spot is connected to it. Below is the blind spot monitor. It is connected to this and it gives signals to its ECU here and there. Here again its light goes on, so now we open it by pushing it and check that to open it, one here is fixed here, one here is fixed here and one is fixed below, its screw and one here is fixed here, so this Its push will come out, in this way our outer mirror assembly has come, see the computer S outer mirror control assembly, it

has two grips, one is A and one is B, now I will get you to check its wiring, I will check. See here you see this is our input and seven and number 13 is green and seven is our ground and this is a grip, this is a grip, this is coming from behind, this is a grip, this is going in and this is not out . So let me find out what is its input. Look from here, there is a doti ch pa 6 sa seven number, this is the ground wire, from here I check my ground first, this is in front of you, this is ground r

, you are seeing negative . Ground is R. Now let's move ahead. 8 Na 10 11 12 13. If you see this number 13 wire, you will see the green wire. This number 13 is our green wire. I will put this number 13 wire here. I am a little bit, you may not be able to see it properly in the camera, but I have connected it to G13 and I will check the voltage. 10.01 See this, the light is half now. I have just taken out the input and the light is half. 10.01 Voltage is coming in it as soon as I turn it on. I wi

ll put it on, you will see that as I put it on, the light is on there and in which wire it is coming out, I will get you to check, these are two, see, one has negative R, it has these 12 numbers and sorry 12 numbers and eight numbers. These two wires you are seeing are number 12 and number 8. Let me check what voltage is coming out. I have installed number 8. You are seeing number 8. The voltage it is producing is 3.4 voltage. This is for our light. Eight number is the wire below it, it has 12 n

umbers, I will check those 12 numbers first for you, which wire is this wire that you are seeing, black red, this is our 12 number, so I connect it to this, so this you are seeing, this is our ground. Number 12 is our ground and number eight is the output coming out, this is our voltage. You will see this. 3.4 So did we understand that the voltage is coming from here and the output is coming from here and the voltage is coming from our BSM. Now what I have done is that I have opened the other si

de also to confirm where our problem is coming from. Now I will take you to the other side also and there we will check our voltage. Yes, right . You will see this wiring on the right side, see on the right side we have number 13 and Sen number is ground, so we are getting 10 voltages in it. In 13, we check whether voltage is coming in this also or not. See, this is our input in this, this is the input and this is the output, so from here I remove its grip, you will see, this is our number 13 gr

ip, this is number 13, sorry, the wire is of green color, so this is this, I put it in this. If you check then number 13 is our wire which is coming from us, it is of green color, there is no voltage in it, so what is there in it, it is coming directly from our BSM, our voltage etc. is not coming in it, and I will check the ground in it, let me check the ground which is in it. The wire is number seven, both are same, Sen and number 13, I am putting this ground, but the green wire in it, our volt

age is not coming in it, that is, this is our BSM, this side is fine, the right side is that. The blind spot monitor system on the side is giving our voltage directly, so now we check that, we will remove the back bumper and I opened it, you can see this is from the right side and this is from the left . The side was of our left side, I take off its grip, this is its grip, and it has a blue wire, our number four, see this, number one, two, three and four, blue wire, this is our wire, let's put i

t now and see what happens. Whether it is giving output or not, then I will put my tester from here, yes, this is my tester, this is my wire, see number four, yes, it is zero volt, here it is absolutely zero volt because I have removed its grip from that side from the computer. The incoming grip is landed, it is landed on this side but the light is ours here, let me check the voltage from here, this is our grip B, from here the output will come out, see in the eight number wire, 3.1, the voltage

is coming, it should be five, but this is 3 points. But it is still on, our light is on, the blanket in the car is off and this wire which will give input to it, this green colored wire will give input, so see green also 3.1 This is a number grip, this is a grip 3.1 Voltages are coming and these are coming Where are these coming from? They are coming from our Blind Spurt and I saw that the grip of Blind Spurt is also taken down. This grip is also taken down but still these volts are coming from

it. So where are they coming from? A little discussion . The next thing is this fault which has become more interesting, now from here I have brought you to the system, you will check from here, this video will be long but in this way, if you understand the fault along with the wiring, then you will find the fault in any vehicle. If anyone is coming then you will be able to solve it very easily, it will be a little long but this video is very interesting for you, so do not skip it, then watch,

I am taking out its wiring from here, I have now drawn the diagram of the system again. I am opening it in front of you, this is our G coming from the left side, this is BSM, you are seeing the blind spot meter left sensor, this is the left sensor and this number four is the wire shown to you, this is ours coming from 13 number A in the grip . Our 3.1 voltage is coming, what can happen now, if you look in this wire This wire is not going straight as you are seeing, this wire is going straight bu

t if you see this wire, there are three characters, one is this, you are seeing these three connectors, one is PU2, HP2 and A2, this is number 12 wire in it. Our number 12, number 23 in this and number 19 in this are these wires, see one, two and three, these three are coming into our connector wire on the left side, so our problem is on the left side, so this is our three wire connector right now which is ours from here. I have cut the grip, this wire has already been cut from here, rest of thi

s wire will remain, so what will we do from here, we will cut one wire from here or from the middle of this wire, take a direct wire from there and check if So we will see that our system becomes OK again, then what we get confirmed will be our problem in this area, so now I do this, I cut the wire number 13 coming from here. And the direct wire which is coming from the blind spot, I connect it here at number four and check that I have connected it. You are seeing that this is wire number four,

I have connected it from here and it is going straight. You are seeing this on number 13. I have put the input here which is A Grip. There I have put my wire in the green wire on number 13. The car is off, you are seeing that our light has been switched off, you will see this. So our light is completely off, now as I start the car, you will see this, I will start it a little, after starting it, it should be on and you can see that it is turning on at the start, it is turning on at the start, the

other side is Let me check the key for you also, you will see that the other side also turns on properly as it is on the original and as soon as I turn it on, this is its blind spurt, from here I can turn it on off as if I turn it off . I will turn it on, see, the light will be on here also, see this, the light will be on here for a while, if I turn it off and turn it on, then our light will be on there also, that is, the problem we have now is gone, I will switch off the car because the issue

Used to come when I switch off the car, look, I have switched off the car. Earlier, our light used to turn on here, now that light is not turning on here, so now the thing that has been confirmed to us is that from here This wire is going from this blind part, it is going from here and coming here, our wire is short from somewhere in all the three connectors, due to which the light coming here is short . If it happens, then the next step is that we have to check all our wiring or all the connect

ors that are coming, you are seeing one, two, three, these three connectors. We have to check where our wire is short or what is the reason for the voltage here. If you are coming then see, I have done the direct wiring, so due to this, our fault goes away, as soon as I touch this wire, here the light comes on. Here, our light comes on as soon as I touch it, a little. There is a touch and our light turns on. Look, you are seeing these two from this side, I turn on the light, then they check the

wire, from where is this short, I have searched for the short and you are seeing these two on this side. I also opened the cover of the car but the wiring here is almost fine. The grip which comes in the front is of blue color from where this wiring is going forward and is going into this pillar. Let me show you the problem in this. Let me take a look. There are two grips. Yes, these are These are going into the pillar and are coming into this door. You will see these two grips on this side. I h

ave opened it and you will see that there is a lot of rust here too. There is a lot of rust in it and this is a big grip. You will also see it in this. So this is rest here too, yes, this is a little bit, I am looking at this, this is our cuprate, that is why our problem is coming, now let's clean it, I will get you checked from here also, see this, this is also a waste in it. And if we look from here, it is exactly this point which is touching us and see this wire going forward from here, this

is the output which is the wire coming out of us, so this is our problem, it is coming in due to which Our issue is coming from here, see this wire which is our green colored wire, this is the output coming out here and there, here this wire is our that one in this grip, you are seeing this one, so now I will clean it. I will plug it in and check whether our fault is solved or not. I have cleaned both the connectors and see that now the meter is absolutely zero. After cleaning it, the main work

that you have to do is to make it happy and correct it. If you use its water which rusts inside etc. If after cleaning it, you are using water or Dedi 40 or any cleaner, if it remains inside it, then the problem will arise. See, both of them have been cleaned, they are absolutely clean, they are dry, both of them. If you see, then a pro tip is that I do a lot of wiring work, so after cleaning the wiring often, I have this Vaseline, I apply it, this ensures that the rust that is there does not co

me back. So, if you do wiring work , you get such connectors, then try this method once and try it. Inshallah, whatever issue you are facing may be related to wiring, if this kind of rusting etc. After cleaning it properly like I have done, the rust will not come there again. This happens when either water goes away or you clean it with cleaner etc., then the cleaner etc. which is there remains inside, which due to staying inside, If there is WD40 etc., it remains inside. Use any cleaner which h

as vaporization. Whatever vaporizes should come out automatically. What does not come out, remains inside due to that, it becomes rust again, so now I will apply it and then you will check. Let me get it done, see, I have put these Vasan etc. on both of them, now let's put them and start the car and check whether the problem we were facing earlier is gone or not, see, I have just put it on and I have my digital tester. Now let's start the car and check it, because in this kind of fault, you shou

ld understand the wiring related thing. If you do not understand the wiring then it will become a problem later. There was no error etc., I will get you to check it on the other side. But it is still working, here also I lower the mirror a little, I will see that the car has started, from here I will turn off and on, then off will also be on, see, the light is coming here also, the light is coming on this side also. Here you will see, I will not turn it off from here with the BSM button, here al

so the light is on and here too, Alhamdulillah, our light is on, our issue was that it used to work from this side, as soon as we switched it off, the light on this side is on. Now you are seeing here that our light is off, the car is off, this is the car is off, if we see that our light is not coming on then how much voltage should be coming to it, like we start the car, it should come to five volts. Look at starting it, there is zero voltage right now, there is nothing in it, as soon as I star

t it, it will come, now I am putting it, I put it a little to the tester, I have this camera in one of my hands, because of that, I am facing a little problem. Let me show you this, see the car on the spot 0.01, this button you are seeing is the BSM button, see this, I turn it off and turn it on, this is also closed, as soon as I turn on the BSM, the lights on both sides are on, both are on. Side lights came on, 5 volts are coming into it, see it is off now, I will turn it on, approximately only

5.4 or 5 volts are coming into it, as soon as the lights come on on both sides, five voltages are coming, so our issue was of shut because the current from here. These 3 volts were coming into it, so the light did not light up completely, it lit up a little and kept on burning and the battery was getting drained because of that, the battery was also getting drained due to this and its BSM was also not working. All other BSM was coming, half was coming from here, BSM was not happening earlier, s

o got the fault etc. checked, there was no fault etc. on the scanner, so in this way we cleared this fault, now I will install all the stuff. Yes, if you like the video, then it is mandatory to like the video. If you are on the channel for the first time, then it is mandatory to subscribe to the channel. Inshallah, I have started a course related to wiring and my series. Have you seen the video? First, I uploaded a video. Inshallah , I will show you how to trace any such fault on these vehicles

, if it is a non-fault like there is no fault in the scanner etc. See, if you do not know about the wiring in this, then this You won't be able to do this for these types of vehicles, so I will try to make you understand the wiring and explain it completely. See you in the next video. Take care of yourself, Allah Hafiz .
