Driver Side Power Mirror Cannot Be Adjusted With Power Mirror Switch
MIRROR: POWER MIRROR CONTROL SYSTEM: Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch
Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch
SYSTEM DESCRIPTION
This circuit detects the conditions of the mirror control switch.
The integration control and panel assembly sends information about the operating condition of the mirror switch (switch input signals) through the BEAN (multiplex communication) line. Then the switch input signals are sent to the front multiplex network door ECU LH. Mirror adjustment is controlled by the front multiplex network door ECU LH.

INSPECTION PROCEDURE
PROCEDURE
1. CHECK POWER MIRROR CONTROL FUNCTION
(a) Using the outer mirror switch, check if the driver side power mirror can be adjusted. Using the retract switch, check if the driver side power mirror can be retracted and returned.
Result:
C -- INSPECT FUSE (FR DOOR LH)
B -- Go to PROBLEM SYMPTOMS TABLE
A -- Continue to next step.
2. READ VALUE USING TECHSTREAM (MIRROR MASTER SWITCH AND MIRROR CONTROL SWITCH)
(a) Check the DATA LIST for proper functioning of the mirror master switch and mirror control switch.
OK:
On tester screen, each item changes between ON and OFF according to above chart.
NG -- REPLACE INTEGRATION CONTROL AND PANEL ASSEMBLY
OK -- Continue to next step.
3. PERFORM ACTIVE TEST USING TECHSTREAM (POWER MIRROR CONTROL FUNCTION)
(a) Select the ACTIVE TEST, use Techstream to generate a control command, and then check the power mirror control function.
Front multiplex network door ECU LH:
Result:
B -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU LH
A -- Continue to next step.
4. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY LH (LEFT / RIGHT MOTOR, UP / DOWN MOTOR)
(a) Remove the mirror LH.
(b) Apply battery voltage and check the operation of the power mirror.
OK:
NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY LH
OK -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU LH
5. INSPECT FUSE (FR DOOR LH)
(a) Remove the FR DOOR LH fuse from the main body ECU LH.
(b) Measure the resistance of the fuse.
Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE
OK -- Continue to next step.
6. CHECK WIRE HARNESS (FRONT MULTIPLEX NETWORK DOOR ECU LH - BATTERY AND BODY GROUND)
(a) Disconnect the M9 ECU connector.
(b) Measure the resistance and voltage of the wire harness side connector.
Standard resistance:
Standard voltage:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU LH
