Power Mirror Cannot Be Adjusted With Power Mirror Switch

MIRROR (EXT): POWER MIRROR CONTROL SYSTEM: Power Mirror cannot be Adjusted with Power Mirror Switch

Power Mirror cannot be Adjusted with Power Mirror Switch

DESCRIPTION

- A switch signal of the outer mirror switch is transmitted to the selected outer mirror control ECU by way of the main body ECU RH. Then, the outer mirror control ECU activates the mirror motor to move the mirror UP, DOWN, RIGHT or LEFT in response to the input.
- Mirror control switch and memorized mirror position signals (from the position control ECU & switch (seat ECU)) are sent to the mirror control ECU. The mirror control ECU moves the selected mirror UP, DOWN, LEFT or RIGHT in response to the input.
NOTICE: The power mirror control system is a part of the multiplex communication system. This system features shared communication wiring that reduces the wiring complexity of the communication lines. The first step in any repair is to confirm the proper operation of the communication system. Proceed with troubleshooting after the communication has been verified (See Multiplex Communication System How to Proceed With Troubleshooting).

PROCEDURE

1. CHECK FOR DTC
(a) Check for multiplex communication system DTCs.
Result:






B -- GO TO MULTIPLEX COMMUNICATION SYSTEM
A -- Continue to next step.
2. INSPECT OUTER MIRROR SWITCH





(a) Remove the outer mirror switch Removal.
(b) Measure the resistance according to the value(s) in the table below when the switch is operated.
Standard Resistance:






NG -- REPLACE OUTER MIRROR SWITCH
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (OUTER MIRROR SWITCH - MAIN BODY ECU RH)





(a) Disconnect the M8 and J74 connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. PERFORM ACTIVE TEST USING TECHSTREAM
(a) Enter the following menus: Body Electrical / Mirror L/Mirror R / Active Test.
(b) According to the display on the Techstream, perform the Active Test.
Mirror L and Mirror R:






NG -- INSPECT OUTER REAR VIEW MIRROR ASSEMBLY
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
5. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY





(a) for LH side
(1) Disconnect the h1 connector.
(2) Apply battery voltage and check the operation of the mirror face.
Standard:










(b) for RH side
(1) Disconnect the g1 connector.
(c) Apply battery voltage and check the operation of the mirror face.
Standard:






NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY
OK -- REPLACE OUTER MIRROR CONTROL ECU
