Auto Power Retract Mirrors Do Not Operate

MIRROR: POWER MIRROR CONTROL SYSTEM (w/ Memory): AUTO Power Retract Mirrors do not operate
- AUTO Power Retract Mirrors do not operate

DESCRIPTION

The circuit detects the conditions of the outer mirror retract switch built into the outer mirror switch assembly. The main body ECU (cowl side junction block RH) detects the operating condition of the outer mirror retract switch. The main body ECU (cowl side junction block RH) sends the outer mirror retract switch condition signal to the outer mirror control ECU assembly via the multiplex communication line.

When the outer mirror control ECU receives an entry lock/unlock signal*1 or wireless lock/unlock signal*2 and AUTO electric retract ON signal from the combination meter assembly via the multiplex communication line while the outer mirror retract switch is in the retract position, the outer mirror control ECU assembly operates the retract motors built into the outer rear view mirrors to retract or return the mirrors.

* *1: When lock/unlock using the smart access system with push-button start

* *2: When lock/unlock using the wireless door lock system

INSPECTION PROCEDURE

PROCEDURE

1. CHECK MULTIPLEX COMMUNICATION SYSTEM

(a) Use the Techstream to check if multiplex communication system is functioning normally How To Proceed With Troubleshooting.

OK:

Multiplex communication DTC is not output.

NG -- GO TO MULTIPLEX COMMUNICATION SYSTEM Multiplex Communication System
OK -- Continue to next step.

2. CHECK AUTO POWER RETRACT MIRROR FUNCTION

(a) Perform an auto power retract mirror function properly On-Vehicle Inspection.

Result:





B -- CHECK POWER RETRACT MIRROR FUNCTION (MANUAL FUNCTION)
A -- Continue to next step.

3. CHECK SMART ACCESS SYSTEM WITH PUSH-BUTTON START (ENTRY FUNCTION)

(a) Check the smart access system with push-button start (entry function) On-Vehicle Inspection.

OK:

Smart access system with push-button start (entry function) is normal.

NG -- GO TO SMART ACCESS SYSTEM WITH PUSH-BUTTON START (PROBLEM SYMPTOMS TABLE) Smart Access System With Push-Button Start
OK -- Continue to next step.

4. CHECK POWER RETRACT MIRROR FUNCTION (MANUAL FUNCTION)

(a) Check the power retract mirror function (manual function) On-Vehicle Inspection.

OK:

Power retract mirror function (manual function) is normal.

NG -- GO TO OTHER FLOW CHART Power Retractable Mirrors Do Not Operate With Power Retract Mirror Switch
OK -- Continue to next step.

5. CHECK AUTOMATIC MEMORY CALL FUNCTION

(a) Perform an automatic memory call function properly Operation Check.

OK:

Automatic memory call function is normal.

NG -- GO TO OTHER FLOW CHART (PROBLEM SYMPTOMS TABLE) Front Power Seat Control System (w/ Seat Position Memory System)
OK -- Continue to next step.

6. CHECK COMBINATION METER ASSEMBLY

(a) Check that AUTO is on in satellite switch mode on the multi-information display System Description.

Result:





NG -- GO TO METER / GAUGE SYSTEM (Satellite Switch Circuit) Satellite Switch Circuit

OK -- REPLACE COMBINATION METER ASSEMBLY Removal

7. CHECK POWER RETRACT MIRROR FUNCTION (MANUAL FUNCTION)

(a) Check power retract mirror function (manual function).

Result:





B -- GO TO OTHER FLOW CHART (Power Retract Mirrors do not Operate) Power Retractable Mirrors Do Not Operate With Power Retract Mirror Switch

A -- REPLACE OUTER MIRROR CONTROL ECU ASSEMBLY Disassembly
