Test 9: Driver's Side Mirror Dimming Activation

Turn ignition switch to RUN position. Ensure interior lights are off. Cover light sensor on back side of interior mirror. Shine a bright light on mirror side of interior mirror. Using a voltmeter, backprobe between terminals No. 7 and 8 at driver's door control module harness connector No. 2. If 0-1.5 volts exists, driver's side mirror dimming activation is okay at this time. If 0-1.5 volts does not exist, check the following as possible cause and repair as necessary:

• Check wiring. See WIRING DIAGRAMS .
• Perform TEST 6: INTERIOR MIRROR DIMMING VOLTAGE SUPPLY .
• Replace interior mirror.
• Replace driver' door control module.
