B105287 — Left rear window lost communication
Quick answer
B105287 means the body controller stopped receiving messages from the left rear window motor. The window normally stops working on that door. The motor or its regulator assembly is the usual part replaced.
What to check first
- Check the 12 V battery state of charge and terminals; a weak 12 V supply causes many electronic faults.
- Check whether other modules on the same network also report communication faults; one module offline can set codes in several others.
- Read all stored fault codes with a scan tool and deal with related codes first.
Can I still drive?
Usually drivable — have it checked soon. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
