Driver Side Or Front Passenger Side Power Mirrors Cannot Be Adjusted With Power Mirror Switch
MIRROR: POWER MIRROR CONTROL SYSTEM: Driver Side or Front Passenger Side Power Mirrors cannot be Adjusted with Power Mirror Switch
- Driver Side or Front Passenger Side Power Mirrors cannot be Adjusted with Power Mirror Switch
DESCRIPTION
The driver side junction block sends power mirror switch signals through the multiplex communication line to the multiplex network door ECU front LH and RH (driver and front passenger door ECU). While the theft warning ECU is sending an ACC signal through the multiplex communication line to the door ECU front LH and RH, the RIGHT, LEFT, UP and DOWN mirror surface operation occurs.

Driver Door, Passenger Door
Result
C -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT RH (FRONT PASSENGER DOOR ECU)
B -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT LH (DRIVER DOOR ECU)
A -- Continue to next step.
2. INSPECT OUTER MIRROR ACTUATOR ASSEMBLY LH OR RH (LEFT / RIGHT MOTOR, UP/ DOWN MOTOR)
(a) Disconnect the R14 or R15 mirror connectors.
(b) Apply battery voltage and check the operation of the mirror.
OK:
Result
C -- REPLACE OUTER MIRROR ACTUATOR ASSEMBLY RH
B -- REPLACE OUTER MIRROR ACTUATOR ASSEMBLY LH
A -- Continue to next step.
3. CHECK WIRE HARNESS (OUTER MIRROR ACTUATOR ASSEMBLY LH OR RH - MULTIPLEX NETWORK DOOR ECU FRONT LH, RH)
(a) Disconnect the R14 or R15 mirror connectors.
(b) Disconnect the D23 or P43 ECU connectors.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:
for Driver side
for Front passenger side
Result
C -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT RH (FRONT PASSENGER DOOR ECU)
B -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT LH (DRIVER DOOR ECU)
A -- REPAIR OR REPLACE HARNESS OR CONNECTOR
