CMAX tailgate hall sensor fault

That's an interesting issue. I had a similar problem with my old Opel Astra, though it was the trunk latch acting up. The error memory kept showing a faulty electrical sensor. Are you sure it's not the tailgate motor itself? Maybe try checking the sensor wiring for any obvious damage or corrosion first. It’s like checking the fuses before tearing apart the engine, you know?

Thanks for the tip! I'll definitely check the wiring more closely. When you had the problem with your Opel, did the error code specifically point to the sensor, or was it more general? I'm just trying to figure out if the hall sensor fault code is a red herring.

The error code on my Astra was pretty specific about the sensor, yes. However, in the end it turned out that the sensor was fine, but the wiring leading to it wasn't. Given the symptoms and the low mileage, I reckon that a visit to the workshop will be useful. In my experience it's like trying to fix a computer issue, sometimes requires professional skills.

Thanks! After checking the wiring myself and finding nothing obvious, I took it to a garage. Turns out you were right about the wiring: the cable to the hall sensor was faulty. Cost me 95€ to repair. Appreciate the help!
