INSPECTION

1. Visually check the ambient sensor for dirt or damage, and clean or replace as necessary.

2. Check the resistance between ambient sensor terminals.

CAUTION:

During inspection, be careful not to touch the sensor end in order to avoid misjudgment due to body temperature.

Preparation tool:

Circuit tester
