Diagnostic Fault Information
Circuit/System Description
The outside rearview mirror switch controls the outside rearview mirrors
based on the position of the mirror
selector switch and which movement position is selected. The outside rearview
mirror switch has four positions:
up, down, left, and right. B+ is applied to the switch from the power mirror
fuse and when a movement position
switch is selected, voltage is sent to the commanded mirror via a mirror control
circuit. The opposite mirror
control circuit acts as a ground circuit for the bi-directional mirror motor.
Ground is the applied through the
switch.

Circuit/System Verification
- Verify the mirror glass of the A9A Outside Rearview Mirror-Driver and
the A9B Outside Rearview
Mirror-Passenger move UP, DOWN, LEFT and RIGHT with the S52 Outside Rearview
Mirror Switch.
- If both outside mirror glasses do not move
Refer to Circuit/System Testing - Both Outside Rearview Mirrors Inoperative.
- If the driver outside mirror glass does not move UP, DOWN, LEFT or
RIGHT
Refer to Circuit/System Testing - Driver Outside Mirror Movement Malfunction.
- If the passenger outside mirror glass does not move UP, DOWN, LEFT or
RIGHT
Refer to Circuit/System Testing - Passenger Outside Mirror Movement
Malfunction.
- If the mirror glass of the A9A Outside Rearview Mirror-Driver and the
A9B Outside
Rearview Mirror-Passenger move UP, DOWN, LEFT and RIGHT
- All OK.
Circuit/System Testing
Both Outside Rearview Mirrors Inoperative
- Ignition OFF and all vehicle systems OFF, disconnect the harness
connector at the S52 Outside Rearview
Mirror Switch. It may take up to 2 minutes for all vehicle systems to power
down.
- Test for less than 10 ohms between the ground circuit terminal 5 and
ground.
- Ignition OFF.
- Test for less than 2 ohms in the ground circuit end to end.
- If 2 ohms or greater, repair the open/high resistance in the circuit.
- If less than 2 ohms, repair the open/high resistance in the ground
connection.
- If less than 10 ohms
- Verify a test lamp illuminates between the B+ circuit terminal 4 and
ground.
- If the test lamp does not illuminate and the circuit fuse is good
- Ignition OFF.
- Test for less than 2 ohms in the B+ circuit end to end.
- If 2 ohms or greater, repair the open/high resistance in the circuit.
- If less than 2 ohms, verify the fuse is not open and there is voltage at
the fuse.
- If the test lamp does not illuminate and the circuit fuse is open
- Ignition OFF.
- Test for infinite resistance between the B+ circuit and ground.
- If less than infinite resistance, repair the short to ground on the
circuit.
- If infinite resistance
- Test for infinite resistance between each of the control
circuit terminals listed below and ground:
- Control circuit terminal 1
- Control circuit terminal 2
- Control circuit terminal 3
- Control circuit terminal 7
- Control circuit terminal 8
- Control circuit terminal 9
- If less than infinite resistance, repair the short to ground on the
circuit.
- If infinite resistance, replace the appropriate M77 Outside Rearview
Mirror Motor.
- If the test lamp illuminates
- Test or replace the S52 Outside Rearview Mirror Switch.
Driver Outside Mirror Movement Malfunction

- If less than infinite resistance, repair the short to ground on the
circuit.
- If infinite resistance
- Test for less than 2 ohms in each control circuit end to end.
- If 2 ohms or greater, repair the open/high resistance in the circuit.
- If less than 2 ohms, test or replace the S52 Outside Rearview Mirror
Switch.
- If the test lamp is always ON
- Ignition OFF, remove the test lamp, disconnect the harness connector at
the S52 Outside Rearview
Mirror Switch, ignition ON.
- Test for less than 1 V between each control circuit and ground.
- If 1 V or greater, repair the short to voltage on the circuit.
- If less than 1 V, test or replace the S52 Outside Rearview Mirror Switch
- If the test lamp turns ON during each of the commands
- Connect a test lamp between the control circuit terminal 1 and control
circuit terminal 3.
