Function Test

NOTE: Before testing, remove the left door panel, then disconnect all connectors from the door panel.

Function Test:

NOTE: Check the No. 4 (15A) fuse in the under-dash fuse box before testing.


One or both inoperative:
1. Check for voltage between the YEL/BLK1 terminal and body ground with the ignition switch ON (II). There should be battery voltage.
- If there is no voltage, check for an open in the YEL/BLK1 wire.
- If there is battery voltage, go to step 2.
2. Check for continuity between the BLK 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, G403).

Left inoperative:
Connect the YEL/BLK terminal to the YEL/RED terminal and the YEL/WHT (or YEL/BLK2) terminal to body ground with jumper wires.
The left mirror should tilt down (or swing left) when the ignition switch is turned ON (II).
- If the mirror does not tilt down (or does not swing left), check for an open in the YEL/WHT (or YEL/BLK2) wire between the left door mirror and the switch.

If the wire is OK, check the mirror.
- If the mirror doesn't move in either direction, repair the YEL/RED wire.
- If the mirror operates properly, check the mirror switch.

Right inoperative:
Connect the YEL/BLK1 terminal to the BLU/GRN terminal and the YEL/WHT (or BLU/BLK( terminal to the body ground with jumper wires.
The right mirror should tilt down (or swing left) when the ignition switch is turned ON (II).
- If the mirror does not tilt down (or does not swing left), remove the right door panel, and check for an open in the YEL/WHT or BLU/BLK) wire between the right door mirror and the switch.

If the wire is OK, check the right door mirror.
- If the mirror doesn't move in either direction, repair the BLU/GRN wire.
- If the mirror operates properly, check the mirror switch.
