- Ignition OFF, disconnect the harness connector at the rearview mirror.
- Test for less than 1 Ξ© of resistance between the ground circuit and ground.
- If greater than 1 Ξ©, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the voltage supply circuit and ground.
- If the test lamp does not illuminate, repair the voltage supply circuit for a short to ground or an open/high resistance.
- With the transmission in PARK, test for less than 0.5 volts between the backup lamp supply voltage circuit and ground.
- If the voltage is greater than 0.6 volt, test the backup lamp supply voltage circuit for a short to voltage.
- With the transmission in REVERSE, test for greater than 11 volts between the backup lamp supply voltage circuit and ground.
- If the voltage is not 12 volts, test the backup lamp supply voltage circuit for an open/high resistance.
- If all circuits test normal, replace the rearview mirror.
