Reverse Shift-Linked Function Of Power Mirrors Does Not Operate
MIRROR: POWER MIRROR CONTROL SYSTEM (w/ Memory): Reverse Shift-linked Function of Power Mirrors does not Operate
Reverse Shift-linked Function of Power Mirrors does not Operate
DESCRIPTION
A/T models:
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.
M/T models:
After the main body ECU RH (cowl side J/B RH) receives a reverse signal from the back up light switch, the ECU sends a reverse signal to the outer mirror control ECU via the BEAN communication system. The outer mirror control ECU activates the mirror motor in response to the reverse signal.

INSPECTION PROCEDURE
PROCEDURE
1. CHECK DTCs
(a) Select the DTC check on Techstream to check for communication errors.
Result:
C -- GO TO CAN COMMUNICATION SYSTEM
B -- GO TO MULTIPLEX COMMUNICATION SYSTEM
A -- Continue to next step.
2. READ VALUE USING TECHSTREAM
(a) Check the DATA LIST for proper function of the reverse signal.
P-J/B:
OK -- INSPECT OUTER REAR VIEW MIRROR ASSEMBLY
NG -- Continue to next step.
3. CHECK VEHICLE TYPE
Result:
B -- CHECK WIRE HARNESS (BATTERY POSITIVE VOLTAGE)
A -- Continue to next step.
4. CHECK WIRE HARNESS (BATTERY POSITIVE VOLTAGE)
(a) Disconnect the E55 connector.
(b) Measure the voltage according to the value(s) in the table below.
Voltage:
NG -- REPAIR OR REPLACE LH-IG FUSE OR HARNESS AND CONNECTOR
OK -- Continue to next step.
5. CHECK WIRE HARNESS (BACK UP LIGHT SWITCH ASSEMBLY - COWL SIDE J/B LH)
(a) Disconnect the E55 and LJ connectors.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:
NG -- REPAIR OR REPLACE WIRE HARNESS
OK -- Continue to next step.
6. INSPECT BACK UP LIGHT SWITCH ASSEMBLY
(a) Disconnect the E55 connector.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:
NG -- REPLACE BACK UP LIGHT ASSEMBLY
OK -- REPLACE MAIN BODY ECU LH
7. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY
(a) Outer rear view mirror LH:
Disconnect the h1 connector.
(b) Apply battery voltage and check operation of the mirror face.
Standard:
(c) Outer rear view mirror RH:
Disconnect the g1 connector.
(d) Apply battery voltage and check operation of the mirror face.
Standard:
NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY
OK -- REPLACE OUTER MIRROR CONTROL ECU
8. CHECK WIRE HARNESS (BATTERY POSITIVE VOLTAGE)
(a) Disconnect the E45 connector.
(b) Measure the voltage according to the value(s) in the table below.
Voltage:
NG -- REPAIR OR REPLACE LH-IG FUSE OR HARNESS AND CONNECTOR
OK -- Continue to next step.
9. CHECK WIRE HARNESS (PARK/NEUTRAL POSITION SWITCH - ECM)
(a) Disconnect the E45 and E4 connectors.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:
NG -- REPAIR OR REPLACE WIRE HARNESS
OK -- Continue to next step.
10. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Disconnect the E45 connector.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:
NG -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
OK -- Continue to next step.
11. REPLACE GATEWAY ECU
(a) Replace the gateway ECU.
NEXT -- Continue to next step.
12. CONFIRM MIRROR OPERATION
NG -- REPLACE ECM
OK -- END
