Power Retractable Mirrors Do Not Operate With Power Retract Mirror Switch

MIRROR: POWER MIRROR CONTROL SYSTEM: Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

SYSTEM DESCRIPTION

This circuit detects the conditions of the mirror retract switch.
The integration control and panel assembly sends information about the operating condition of the mirror retract switch (switch input signals) through the BEAN line. Then the switch input signals are sent to the front multiplex network door ECU LH and RH.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK POWER MIRROR CONTROL FUNCTION
(a) Using the outer mirror switch, check if the power mirrors can be adjusted.
Result:






B -- GO TO PROBLEM SYMPTOMS TABLE
A -- Continue to next step.
2. CHECK MIRROR RETRACT FUNCTION
(a) Check that the driver side and passenger side mirrors retract normally when operating the mirror retract switch.
Result:






B -- READ VALUE USING TECHSTREAM (MIRROR RETRACT SWITCH)
A -- Continue to next step.
3. PERFORM ACTIVE TEST USING TECHSTREAM (MIRROR RETRACT FUNCTION)
(a) Select the ACTIVE TEST, use Techstream to generate a control commend, and then check the mirror retract function.
Front multiplex network door ECU LH, RH:






Result:
Front multiplex network door ECU LH:






Result:
Front multiplex network door ECU RH:






D -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU RH
C -- INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH (RETRACTABLE MIRROR MOTOR)
B -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU LH
A -- Continue to next step.
4. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY LH (RETRACTABLE MIRROR MOTOR)





(a) Remove the mirror LH.
(b) For each mirror position:
Disconnect the battery, set the mirror position by hand, connect the battery, and check the retractable mirror's movement.
NOTICE:
- Disconnect and reconnect the battery once between each mirror position check.
- The mirror position cannot be changed manually when the battery is connected. To change the mirror position manually, the battery must be disconnected first.

OK:






NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY LH
OK -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU LH
5. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH (RETRACTABLE MIRROR MOTOR)





(a) Remove the mirror RH.
(b) For each mirror position:
Disconnect the battery, set the mirror position by hand, connect the battery, and check the retractable mirror's movement.
NOTICE:
- Disconnect and reconnect the battery once between each mirror position check.
- The mirror position cannot be changed manually when the battery is connected. To change the mirror position manually, the battery must be disconnected first.

OK:






NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY RH
OK -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU RH
6. READ VALUE USING TECHSTREAM (MIRROR RETRACT SWITCH)
(a) Check the DATA LIST for proper functioning of the mirror retract switch.
Integration control and panel assembly:






OK:
On tester screen, each item changes between ON and OFF according to above chart.
NG -- REPLACE INTEGRATION CONTROL AND PANEL ASSEMBLY
OK -- REPLACE FRONT MULTIPLEX NETWORK DOOR ECU (LH, RH)
