Sail Solar Sensor Fault

Greetings. I, too, have encountered a similar predicament, albeit with a vehicle of different manufacture. My experience pertains to a 2018 Volvo XC60. The symptoms you describe, specifically the error memory storage and diminished heating efficacy, mirror my own experience. Could you elaborate on the diagnostic procedures you have undertaken thus far? Further clarification regarding the specific error code would be most beneficial.

Okay, interesting. With my Chevy Sail the error code is B1000-11. I visually inspected the sensor and the connector. I tried to check voltage on the connector, but the wiring diagram is a mess. Did you also check wiring and plugs, or what exactly did you do?

In response to your query, I confirm that I also undertook a comprehensive examination of the wiring and plug connections pertinent to the solar sensor apparatus within my Volvo XC60. The diagnostic outcome proved inconclusive despite my best efforts. Regrettably, the intricacies of modern automotive electrical architecture often necessitate specialized diagnostic tools and expertise. Therefore, I would recommend engaging a certified automotive service technician to address this issue in a proper workshop.

Thanks. I was hoping it would be a simple fix. I took your advice and brought it to a shop. Turns out you were right - a defective cable/plug. The bill came to 95€, so not too bad. Thanks for the reality check!
