Reverse Shift-Linked Function Of Power Mirrors Does Not Operate

MIRROR (EXT): POWER MIRROR CONTROL SYSTEM: Reverse Shift-linked Function of Power Mirrors does not Operate

Reverse Shift-linked Function of Power Mirrors does not Operate

DESCRIPTION

After the ECM receives a reverse signal from the park/neutral position switch, the ECM sends a reverse signal to the outer mirror control ECU via the CAN and BEAN communication systems. The outer mirror control ECU activates the mirror motor in response to the reverse signal.
NOTICE: The reverse shift linked unction of the power mirrors will not operate when the mirror select switch is in the neutral position (between "L" and "R").

INSPECTION PROCEDURE
NOTICE: The reverse shift linked unction of the power mirrors will not operate when the mirror select switch is in the neutral position (between "L" and "R").

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM
(a) Check for CAN communication system DTCs How to Proceed With Troubleshooting.
HINT: If CAN communication system DTCs are output, inspect those DTCs first.

OK:
DTC is not output.
NG -- GO TO CAN COMMUNICATION SYSTEM (HOW TO PROCEED WITH TROUBLE SHOOTING)
OK -- Continue to next step.
2. CHECK MULTIPLEX COMMUNICATION SYSTEM
(a) Check for multiplex communication system DTCs Multiplex Communication System.
HINT: If multiplex communication system DTCs are output, inspect those DTCs first.

OK:
DTC is not output.
NG -- GO TO MULTIPLEX COMMUNICATION SYSTEM (DIAGNOSTIC TROUBLE CODE CHART)
OK -- Continue to next step.
3. CHECK FOR DTC (SFI SYSTEM)
(a) Check for DTC P0705 (Transmission Range Sensor Circuit Malfunction).
HINT: If the DTC P0705 (Transmission Range Sensor Circuit Malfunction) is output, inspect that DTC first.

NG -- GO TO SFI SYSTEM (DTC P0705)
OK -- Continue to next step.
4. PERFORM ACTIVE TEST USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Enter the following menus: Body Electrical / Mirror L/Mirror R / Active Test.
(d) According to the display on the Techstream, perform the "Active Test".
Mirror L and Mirror R:






OK:
Mirror function is normal.
NG -- INSPECT OUTER REAR VIEW MIRROR
OK -- Continue to next step.
5. REPLACE OUTER MIRROR CONTROL ECU
(a) Replace the outer mirror control ECU with a normally functioning ECU or new one Removal.
NEXT -- Continue to next step.
6. CONFIRM POWER MIRROR OPERATION
(a) Turn the engine switch on (IG).
(b) Make sure that the brake pedal is depressed.
(c) Move the shift lever from P to R.
(d) Check reverse shift-linked function.
OK:
Reverse shift-linked function is normal.
NG -- REPLACE GATEWAY ECU
OK -- END
7. REPLACE GATEWAY ECU
(a) Replace the gateway ECU with a normally functioning ECU or new one.
NEXT -- Continue to next step.
8. CONFIRM POWER MIRROR OPERATION
(a) Turn the engine switch on (IG).
(b) Make sure that the brake pedal is depressed.
(c) Move the shift lever from P to R.
(d) Check reverse shift-linked function.
OK:
Reverse shift-linked function is normal.
NG -- REPLACE ECM
OK -- REPLACE OUTER REAR VIEW MIRROR
9. INSPECT OUTER REAR VIEW MIRROR





(a) for LH side
(1) Remove the outer rear view mirror Removal.
(2) Apply battery voltage and check the operation of the mirror face.
Standard:










(b) for RH side
(1) Remove the outer rear view mirror Removal.
(2) Apply battery voltage and check the operation of the mirror face.
Standard:






NG -- REPLACE OUTER REAR VIEW MIRROR
OK -- REPLACE OUTER MIRROR CONTROL ECU
