Power Mirror Control Module: Testing and Inspection

MEMORY HEATED SEAT / MIRROR MODULE (MHSMM)
Before testing the Memory Heated Seat / Mirror Module (MHSMM), test the heated seat switches, the heated seat elements, and the heated seat sensors. If there are no problems, proceed as follows:
- Replace the current MHSMM with a known good module, and test the operation of the heated seats. If OK, discard the faulty MHSMM. If the problem persists, proceed.
- Test each of the circuits from the heated seat switch, elements, and sensors to the MHSMM. Repair any shorts or open circuits as required.
