XC70 Central Locking Failure
Summary of the thread
A 2012 Volvo XC70 experienced a complete failure of the central locking system, with neither the remote nor keyless entry functioning. Initial checks, including fuses and battery, appeared normal, leading to suspicion of a faulty actuator. However, the issue was resolved by repairing a defective plug connection in the door, which restored the system's functionality.

The car battery seems fine, it's cranking and starting without any issues, and all the other electrical systems are working properly. The error code is a bit vague; it's pointing to a potential wiring issue or a faulty component within the central locking system. Do you know which component the error refers to, or have any tips for diagnosing the wiring?

Right, if the battery's good and the error is vague, it sounds like you're chasing a ghost in the machine. I'd say it's time to bite the bullet and get it checked by a workshop. They have the proper diagnostic tools to pinpoint the fault. Could be a dodgy connection or a control module issue.

Thanks for the advice. I took it to a local shop, and it turned out to be a defective plug connection in the door. They fixed the cable and the plug, cleared the error memory, and now it's working perfectly again. The total repair cost was 95€. I appreciate your help!

That's a strange one. You're sure it's not the car battery itself? Sometimes low voltage can cause weird electrical gremlins. Is the error message specific, or just a generic 'central locking fault'?
