    Headlight Range (J431), Can someone decipher these codes for me?

    Hi I got these codes which won't go away and the adaptive light in the dashboard is always on.

    The two codes relating to this headlight range fall under 2 addresses:

    1. Address 09: Cent. Elect. (J519)

    1 Fault Found:
    01771 - Control Module for Headlight Range (J431)
    013 - Check DTC Memory
    Freeze Frame:
    Fault Status: 01101101

    Mileage: 167382 km
    Time Indication: 0
    Date: 2019.11.29
    Time: 17:28:00

    2. Address 55: Headlight Range (J431)

    1 Fault Found:
    0061 - Function Restriction due to Implausible Message(s)
    U1112 00 [137] - -
    [Fehlerhafter DLC der CAN-Messages Kamera_Status (0x318)]

    Date: 2019.11.29
    Time: 17:28:52

    Can someone tell me what is these codes are trying to say. It hard for me since no faulty parts is mentioned. Most of the 01771 codes I've read will show some faulty parts (like the level sender) to be replaced. This adaptive light in the instrument cluster has been an eye sore for months. Your help is appreciated. The full scan is below.

    The 55- Headlight Range module is unhappy about something with 85 - On Board Cam. (J852), but it is not clear what.

    -Uwe-
    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    ^^^^ coconutaudi: Hi. If I might add to Uwe's observation - perhaps look at the records in CodingLog.CSV and AdpLog.CSV files in the C:\Ross-Tech\VCDS\Debug directory on the laptop that you use for VCDS for any changes that were made to the car on 29th November 2019 @ about 5:30 PM.

    Uwe, up until now, I don't even realize that I have an onboard camera in my car, especially since I don't have this lane departure warning system or any system that uses an onboard camera. Not to my limited knowledge at least. So it is baffling as to how these two J431 and J852 are related. Maybe we can explore further from this info.

    Nevertheless thank you for the info.

    Hi Don, no changes was made on the 29th Nov @ 5.30pm. The only change I've made was on 27th Nov when I changed the battery serial number because I've replaced the battery. And this headlight range problem has been bugging me for months.

    Hi, In your service folder, first page(s), in the rows with many 3 letter/numbers, does one combo say 8Q3?
    I think the cam is used by the Auto dimming/full light function (AFS).
    Have you checked wiring to level sensors on drivetrain pressune left side front and rear? Also check fuse 8 in fuseholder C, this is J745 control module for corn light and headlight range control. Which also has CAN hi&lo

    Regards
    Gremling

    Hi Gremling,
    I've checked and my options didn't include 8Q3. I found the list in the spare tire compartment. But I noticed my car has AFS13 stated in address 55 along with EV_AdvanFrontSyste, if indeed they are the same thing as the AFS you've mentioned. As suggested I will check fuse 8 in fuseholder C along with the fuse for the onboard camera (fuse 11 on fuseholder B) as there might be problem as pointed out by Uwe. As for the level sensors, I will check them too once I can get the car lifted.

    Thank you for the suggestions. I will update you guys.

    Thank you.

    So I've checked the followings
    1. the fuse for the headlight range control J431 and it is good (fuse 8 in fuseholder C passenger side)
    2. the fuse for the onboard camera which is also ok (fuse 11 on fuseholder B driver side)
    3. the front left level sender (G78). No corrosion, wires are intact, no water ingress
    4. the rear left level sender (G76). No corrosion, wires are intact, no water ingress

    Those are the things which I have ruled out as being the source of the problem.

    What is the next step? I'm thinking of replacing the headlight range control unit J431 next. My questions are:
    1. Can I just swap the new J431 with the old one (part no 4H4 907 357 A)?
    2. Do I need to code the new J431 unit and how do I go about it using the VCDS.
    3. I've noticed that under address 55 there is Coding: 1121A633F918EB00. Is this the code we need to enter to the new unit?

    Thanks a lot in advance.

    Regards
