*1: With ACCS (advanced climate control system)
*2: Perform self-diagnosis under sunshine. When performi
ng indoors, aim a light (more than 60 W) at sunload
sensor, otherwise self-diagnosis indicates even though the sunload sensor is functioning normally.
NOTE:
If all of door motor DTCs (B2632, B2633, B2634, B2635, B2636, B2637, B2638, B2639, B263D, B263E,
B263F, B2654, B2655, B2661, B2662, B2663, B2664, B 2665, B2666, B2669, and B266A) are detected, check
door motor communication circuit. Refer to HAC-120, "
Diagnosis Procedure".
