Master Central Locking Failure

Central locking on my 2018 Renault Master electric with 112707 km has stopped working. Doors won't lock or unlock via the central system, and there's an error stored. I suspect a bad cable or plug.

Summary of the thread

The central locking system on a 2018 Renault Master electric vehicle stopped working, with doors failing to lock or unlock and an error stored. The initial suspicion was a bad cable or plug. Suggestions included checking for blown fuses and investigating the driver's side door locking mechanism. Ultimately, the issue was identified as a faulty plug connection in the security system, which was resolved at a workshop.

Ah, a common gremlin! Have you checked the fuse box for blown fuses? A faulty fuse could easily disrupt the entire central locking system. Also, has anyone investigated the locking mechanism in the driver's side door? Sometimes a simple mechanical failure there can cascade into electrical problems.

Thanks for the suggestions. Which specific fuse would govern the central locking? And is there a reliable way to test the driver's side locking mechanism without dismantling the entire door?

Unfortunately, without the specific wiring diagrams for your Master, pinpointing the exact fuse is difficult; consult your owner’s manual for fuse locations or a wiring schematic. As for testing the driver's side mechanism, it's quite difficult without specialized tools. Given the symptoms and error codes, a workshop visit may be necessary. They will have diagnostic tools to isolate the fault. I assume you checked the basics?

Understood. I appreciate your input. I took it to the workshop, and as suspected, it was indeed a faulty plug connection in the security system. The repair cost 95€.
