Essentia door handle electronics failure

I'm having an issue with my 2021 Chevrolet Essentia gasoline. At 184546 km, the door handle electronics are failing. The keyless access system is dead, and there's an error code. Diagnostics point to a bad cable or plug. Any ideas?

Summary of the thread

The 2021 Chevrolet Essentia experienced a failure in the door handle electronics, specifically affecting the keyless access system and generating an error code. Diagnostics suggested the issue might be due to a faulty cable or plug. A similar problem in another vehicle pointed to potential wiring harness issues, but ultimately, the solution for the Essentia was replacing a defective door handle cable.

I had a similar issue with my 2018 Opel Insignia. Keyless entry stopped working, and the error memory showed a fault with the door actuator. Check the wiring harness that goes into the door - they can get brittle and crack.

Thanks. Where is the wiring harness located, and do I need special tools to get to it? I want to check it before going to a workshop.

On the Insignia, the harness was located where the door connects to the car's body, inside a rubber boot. It's a tight fit, so you'll need some small tools to pry it open and inspect the wires. Given the symptoms and error code, it might be best to just have a workshop run a diagnostic; I ended up needing a new door actuator.

I consulted a certified workshop. It was a defective door handle cable, now replaced for 95€.
