Power Mirror Function Test

Function Test - Without DPMS





1. Remove the driver's door switch trim.
2. Disconnect the 10P connector (A) from the power mirror switch (B).
3. Choose the appropriate test based on the symptom:
- Both mirrors don't work, go to step 4.
- Left mirror doesn't work, go to step 6.
- Right mirror doesn't work, go to step 7.
- Defoggers don't work, go to step 8.

Both mirrors

4. Check for voltage between the No. 1 terminal and body ground with the ignition switch ON (II). There should be battery voltage.
- If there is no battery voltage, check for:
- blown No. 4 (7.5 A) fuse in the driver's under- dash fuse/relay box.
- an open in the ORN wire.

- If there is battery voltage, go to step 5.

5. Check for continuity between the No. 2 terminal and body ground.
There should be continuity.
- If there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G601).

- If there is continuity, check both mirrors individually as described in step 6 and 7.

Left mirror

6. Connect the No. 1 terminal to the No. 7 terminal, and the No. 4 (or No. 9) terminal to body ground with jumper wires. The left mirror should tilt down (or swing left) with the ignition switch ON (II).
- If the mirror does not tilt down (or does not swing left), check for an open in the BLU/WHT (or BLU/ORN) wire between the left mirror and the lop connector. If the wire is OK, check the left mirror actuator.
- If the mirror neither tilts down nor swings left, check for an open in the BLU/GRN wire.
- If the mirror works properly, check the mirror switch.

Right mirror

7. Connect the No. 1 terminal to the No. 8 terminal, and the No. 4 (or No. 10) terminal to body ground with jumper wires. The right mirror should tilt down (or swing left) with the ignition switch ON (II).
- If the mirror does not tilt down (or does not swing left), check for an open in the BLU/WHT (or LT GRN) wire between the right mirror and the lop connector.
If the wire is OK, check the right mirror actuator.
- If the mirror neither tilts down nor swings left, check for an open in the YEL/WHT wire.
- If the mirror works properly, check the mirror switch.

Defogger

8. Connect the No. 3 and No. 6 terminals with a jumper wire, and check for voltage between the No. 3 terminal and body ground. There should be battery voltage and both mirrors should warm up with the ignition switch ON (II).
- If there is no voltage or neither warms up, check

for:
- an open in the ORN and ORN/WHT wires.
- blown No. 4 (7.5 A) fuse in the driver's under-dash fuse/relay box.
- poor ground (G601, G651).

- If only one fails to warm up, check its defogger.
- If both warm up, check the defogger switch.
