    Hello.
    Laguna II 1.9 DCI dynamique accident version (side curtain shot from the driver and seat cushion). After replacing the cushions, impact sensors, the AirBag module and the system configuration, the AirBag indicator on the dashboard is still lit (without the SERVICE indicator) although the system does not show any error, the steering lock (which cannot be diagnosed by CLIP) does not work, and automatic closing door while driving.
    I am asking for help in solving the problem

    The module has been replaced with identical markings (this was done by car electronics). The car starts without any problems.

    What mistakes in UCH? Lack of blocking and locking after starting is a consequence of glowing airbag.

    Errors in UCH:
    1. DF053 - Car speed information - 1.DEF
    2. DF052 - Receiver of signals sent by the pressure sensor - 1.DEF
    I can add screen parameters if it helps.

    There is no option that the cushion is lit for no reason, scan all the modules because there must be a bull somewhere. Option two - poorly made sensor.

    See if you can enter the parameters of the airbag system through a clip or other interface. You probably have a badly made driver. After an accident, in this lagoon, you need to "repair" the controller on the table. Once an experienced electronics technician told me that it is better to clean the old driver what was in the car than to configure a new one.

    You can enter the parameters of the AirBag system without any problem and configure it, but it doesn't do anything. Unfortunately, I don't have the old module anymore.

    This is a new controller for the table and proven content inside.

    In the week I will pull it out and program it again. I'll let you know how it went.

    Find parameters such as controller status or controller lock in parameters. It should be "unlocked" l
    ub "inactive".

    I would still try to look for an option that allows you to control the steering wheel lock with a computer and see if it can be done.

    There is no on / off airbag switch on the passenger side

    See in the parameters you have the passenger airbag blocked. I'm wrong, correct me

    The problem is solved, it turned out that the path in the AirBag driver is damaged, namely path 58 (CAN H), Clip sometimes showed that the multiplex network was damaged. After improving the soldering binder on the AirBag controller board and repairing the path, everything returned to normal, i.e. no indicator light, working steering lock after removing the card and locking the door when moving off. I attach demonstrative photos. Greetings to all and thank you for your interest in the topic. I consider the topic closed.

Topic summary

The discussion revolves around a persistent AirBag indicator light issue in a Renault Laguna II 1.9 DCI Dynamique following an accident. Despite replacing the airbag cushions, impact sensors, and the AirBag module, the indicator remains lit without any error codes. Users suggest checking the UCH for errors, particularly related to car speed information and pressure sensor signals. The original poster confirms the module was replaced with an identical one and that the car starts normally. Further troubleshooting reveals a damaged path in the AirBag driver, specifically path 58 (CAN H), which was repaired, resolving the indicator light issue and restoring functionality to the steering lock and automatic door locking.
