Function Test

NOTE: Before testing, check the No. 9 (7.5 A) fuse in the under-dash fuse/relay box.

1. Remove the driver's door panel.




2. Disconnect the 10P and 2P connector(s) from the power mirror switch.

Mirror Test
One or both inoperative:
1. Check for voltage between the A9 terminal and body ground with the ignition switch ON (II).
There should be battery voltage.
^ If there is no battery voltage, check for an open in the YEL/BLK wire.
^ If there is battery voltage, go to step 2.
2. Check for continuity between the A10 terminal and body ground.
There should be continuity.
^ If there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G401, G402).

Left mirror inoperative:
1. Connect the A9 terminal to the A7 terminal, and A5 (or A4) 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 10P connector.
- faulty left mirror actuator.
^ If the mirror neither tilts down nor swings left, repair the BLU/GRN wire.
^ If the mirror works properly, check the mirror switch.

Right mirror inoperative:
1. Connect the A9 terminal to the A6 terminal, and A5 (or A3) 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 LT GRN) wire between the left mirror and the 10P connector.
- faulty right mirror actuator.
^ If the mirror neither tilts down nor swings left, repair the YEL/WHT wire.
^ If the mirror works properly, check the mirror switch.

Defogger test (Canada):
1. Check for voltage between the B2 terminal of the 2P connector and body ground with the ignition switch ON (II).
There should be battery voltage.
^ If there is no voltage, check for:
- poor ground (G401, G402),
- an open in the YEL/BLK wire,
^ If there is battery voltage, go to step 2.
2. Connect the power mirror defogger 2P connector B1 and B2 terminals with a jumper wire. Both the right and left mirrors should gradually warm up when the ignition switch is turned ON (II).
^ If neither mirror warms up, repair the ORN/WHT wire.
^ If only one fails to warm up, check its mirror defogger element.
^ If both mirrors warm up, check the defogger switch.
