Mirrors: Testing and Inspection

DIAGNOSIS AND TESTING - POWER MIRRORS

WIRING VOLTAGE TEST (LHD)

The following wiring test determines whether or not voltage is continuous through the body harness to switch.

1. Remove the power mirror switch.
2. Disconnect wire connector from back of power mirror switch.
3. Connect the clip end of a 12 volt test light to Pin 7 in the harness connector at the mirror switch. Touch the test light probe to Pin 3.
If the test light illuminates, the wiring circuit between the battery and switch is OK.

If the lamp does not illuminate, first check the fuse in the Totally Integrated Power Module (TIPM). If the fuse is OK, then check for a broken wire.

Refer to the appropriate wiring information.

POWER MIRROR MOTOR TEST (LHD)

If the power mirror switch is receiving proper current and ground and mirrors do not operate, proceed with power mirror motor test. Refer to the appropriate wiring information.

1. Disconnect wire harness connector to power mirror switch.
2. Using two jumper wires:
- Connect one to a 12 volt source
- Connect the other to a good body ground
- Refer to the Mirror Motor Test Chart for proper wire connections at the switch connector.





3. If results shown in table are not obtained, check for open or shorted circuit. Replace mirror assembly as necessary.
