ELECTRIC CONTROL OUTSIDE REARVIEW MIRRORS DIAGNOSIS PROCEDURE

Step Action Value (s) Yes No
1 Check fuse F8.
Is fuse F8 blown?		 - Go to Step 2 Go to Step 3
2
  1. Check for a short circuit and repair it, if necessary.
  2. Replace fuse F8.

Is the repair complete?		 - System OK -
3
  1. Turn the ignition ON.
  2. Check the voltage at fuse F8.

Is the voltage at F8 equal to the specified value?		 11 - 14 V Go to Step 5 Go to Step 4
4 Repair the open power supply circuit for fuse F8.
Is the repair complete?		 - System OK -
5 Check the electric control outside rearview mirrors.
Are both electric control outside rearview mirrors inoperative?		 - Go to Step 6 Go to Step 13
6
  1. Remove the retaining screw for the electric control outside rearview mirror and power window switch assembly.
  2. Lift the switch assembly so that the connectors on the underside are visible.

Is the connector secured to the electric control outside rearview mirror switch?		 - Go to Step 8 Go to Step 7
7 Connect the connector to the electric control outside rearview mirror switch.
Is the repair complete?		 - System OK -
8 Use an ohmmeter to check the continuity between terminal 6 (BLK) of the electric control outside rearview mirror switch connector and ground.
Does the ohmmeter indicate the specified value?		 0 Ω Go to Step 10 Go to Step 9
9 Repair the open ground circuit for the electric control outside rearview mirror switch.
Is the repair complete?		 - System OK -
10
  1. Turn the ignition ON.
  2. Check the voltage at terminal 8 (BRN) of the electric control outside rearview mirror switch connector.

Is the voltage equal to the specified value?		 11 - 14 V Go to Step 12 Go to Step 11
11 Repair the open power supply circuit for the electric control outside rearview mirror switch.
Is the repair complete?		 - System OK -

  1. On the side which has the inoperative mirror, remove the black plastic escutcheon from the trim panel side of the door.
  2. Disconnect the electric control outside rearview mirror electrical connector.
  3. Turn the ignition ON.
  4. At the electric control outside rearview mirror connector, connect a voltmeter between terminal 4 (GRY) and terminal 6 (LT GRN if testing the driver side or PPL/WHT if testing the passenger side).
  5. Operate the in/out adjustment on the switch, and record the voltage indicated in each switch position.
  6. Connect a voltmeter between terminal 4 (GRY) and terminal 7 (LT GRN if testing the left side or RED/WHT if testing the right side).
  7. Operate the up/down adjustment on the switch, and record the voltage indicated in each switch position.

Does the voltmeter indicate the specified voltage for each test, with the polarity reversing when the switch is changed from in to out or up to down?		 11 - 14 V Go to Step 14 Go to Step 15
14 Replace the electric control outside rearview mirror.
Is the repair complete?		 - System OK -
15
  1. Remove the retaining screw for the electric control outside rearview mirror and power window switch assembly.
  2. Lift the switch assembly so that the connectors on the underside are visible.
  3. Leave the electric control outside rearview mirror disconnected, but do not disconnect the mirror switch connector.
  4. Turn the ignition ON.
  5. At the electric control outside rearview mirror switch connector, backprobe to measure the voltage between terminal 4 (GRY) and terminal 6 (LT GRN if testing the left side or GRN/BLK if testing the right side).
  6. Operate the in/out adjustment on the switch, and record the voltage indicated in each switch position.
  7. Connect a voltmeter between terminal 4 (GRY) and terminal 7 (WHT if testing the left side or RED/WHT if testing the right side.
  8. Operate the up/down adjustment on the switch, and record the voltage indicated in each switch position.

Does the voltmeter indicate the specified voltage for each test, with the polarity reversing when the switch was changed from in to out or up to down?		 11 - 14 V Go to Step 16 Go to Step 12
16 Repair the open circuit between the electric control outside rearview mirror switch and the electric control outside rearview mirror connector.
Is the repair complete?		 - System OK -
