Power Retractable Mirrors Do Not Operate With Power Retract Mirror Switch

MIRROR (EXT): 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

The main body ECU (multiplex network body ECU) receives the outer mirror retract switch signal from the multiplex network master switch assembly via LIN communication. The main body ECU then sends the mirror retract/return signal to each outer mirror control ECU assembly via CAN communication. Based on the signal, each outer mirror control ECU assembly retracts or returns the outer rear view mirror assembly.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

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

OK:

CAN communication DTC is not output.

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

2. CHECK LIN COMMUNICATION SYSTEM

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

OK:

LIN communication DTC is not output.

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

3. READ VALUE USING TECHSTREAM (OUTER MIRROR RETRACT SWITCH)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Master Switch / Data List.

(e) Read the Data List according to the display on the Techstream.

Master Switch





OK:

On the Techstream screen, ON or OFF is displayed for each item according to the above.

NG -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY Removal
OK -- Continue to next step.

4. PERFORM ACTIVE TEST USING TECHSTREAM (MIRROR RETRACT FUNCTION)

(a) Enter the following menus: Body Electrical / Mirror L or Mirror R / Active Test.

(b) Perform the Active Test according to the display on the Techstream.

Mirror L / Mirror R





Result:





B -- INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH

C -- INSPECT OUTER REAR VIEW MIRROR ASSEMBLY LH
A -- Continue to next step.

5. REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU)

(a) Replace main body ECU (multiplex network body ECU) Removal.

NEXT -- Continue to next step.

6. CHECK POWER RETRACT MIRROR FUNCTION

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

OK:

Power retract mirror function (manual function) is normal.

NG -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY Removal

OK -- END (MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) WAS DEFECTIVE)

7. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH

(a) Remove the outer rear view mirror assembly RH Removal.





(b) When checking each mirror position, set the mirror position by hand. Apply auxiliary battery voltage and check the mirror movement.

NOTICE:
* Disconnect and reconnect the auxiliary battery for each mirror position check.
* The mirror position cannot be changed manually when the auxiliary battery is connected. To change the mirror position manually, the auxiliary battery must be disconnected first.

OK:





NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY RH Removal

OK -- REPLACE OUTER MIRROR CONTROL ECU ASSEMBLY (FRONT PASSENGER SIDE) Removal

8. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY LH

(a) Remove the outer rear view mirror assembly LH Removal.





(b) When checking each mirror position, set the mirror position by hand. Apply auxiliary battery voltage and check the mirror movement.

NOTICE:
* Disconnect and reconnect the auxiliary battery for each mirror position check.
* The mirror position cannot be changed manually when the auxiliary battery is connected. To change the mirror position manually, the auxiliary battery must be disconnected first.

OK:





NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY LH Removal

OK -- REPLACE OUTER MIRROR CONTROL ECU ASSEMBLY (DRIVER SIDE) Removal
