Trafic alarm malfunction

I'm having trouble with the anti-theft alarm on my 2011 Renault Trafic diesel. There's an error stored, and the alarm isn't working. The van has 177658 km on it. I've checked the battery, but the problem is still there. Could this be the alarm control module or the immobilizer?

The anti-theft alarm on a 2011 Renault Trafic diesel was malfunctioning, with an error stored and the alarm not working. The issue was suspected to be related to the alarm control module or immobilizer. It was suggested that the problem might be linked to the alarm system's configuration, specifically the optical locking feature. After taking the vehicle to a workshop, the alarm system was recoded, resolving the issue.

I had a similar issue with my Trafic. Do the indicators flash when you lock the car? It might be coded to activate optical locking, which can sometimes mess with the alarm.

Thanks for the reply. Yes, the indicators flash when locking. Are you saying the indicator flashing is causing the problem? How did you fix it?

In my case, the indicator flashing was linked to the alarm problem. I'd suggest getting a workshop to check the alarm system's configuration. They should be able to pinpoint the exact cause and reprogram it if needed.

Thanks for the advice. I took it to a workshop, and it turned out the alarm system was coded to activate the optical locking, which was causing the issue. Recoding it fixed the problem. The repair cost 45€ Thank you again.
