Tacuma Sunroof Initialization Error

I had something very similar happen with my Tacuma. Did you try resetting the sunroof control module? Sometimes a glitch in the system can cause these symptoms. It's worth checking the wiring harness and connections to the sunroof motor too, ensuring everything is secure and free from corrosion. Give that a shot before anything else.

Thanks! Where exactly is the sunroof control module located? And is it easy to get to, or do I need to take half the car apart?

On the Tacuma, the sunroof control module is typically located behind the interior light or near the sunroof motor itself. Access can vary, but usually involves removing the interior light fixture or the headliner around the sunroof opening. Proceed with caution, as forcing any panels can damage them. However, since you mentioned recent coding, a diagnostic scan might pinpoint the exact issue before you start disassembling anything. In my case, a trip to the workshop was unavoidable; it’s best to have it properly diagnosed and potentially reprogrammed.

Thanks a lot for the advice! It turned out you were right, it needed a reset at the workshop, and they recoded it. Cost me 75€, but at least it's working again.
