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

After the transmission control ECU receives a reverse signal from the park/neutral position switch, transmission control ECU the sends a reverse signal to the outer mirror control ECU via the CAN communication systems. 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:





B -- GO TO CAN COMMUNICATION SYSTEM How to Proceed With Troubleshooting
A -- Continue to next step.

2. READ VALUE USING TECHSTREAM

(a) Check the DATA LIST for proper function of the reverse signal.

ECT:





OK -- INSPECT OUTER MIRROR ACTUATOR ASSEMBLY
NG -- Continue to next step.

3. CHECK WIRE HARNESS (BATTERY POSITIVE VOLTAGE)

(a) Disconnect the B36 connector.





(b) Measure the voltage according to the value(s) in the table below.

Standard voltage:





NG -- REPAIR OR REPLACE GAUGE NO. 1 FUSE OR HARNESS AND CONNECTOR
OK -- Continue to next step.

4. CHECK WIRE HARNESS (TRANSMISSION CONTROL ECU - PARK/NEUTRAL POSITION SWITCH)

(a) Disconnect the B36 and B40 connectors.





(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPAIR OR REPLACE WIRE HARNESS
OK -- Continue to next step.

5. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

(a) Disconnect the B36 connector.





(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
OK -- Continue to next step.

6. CONFIRM MIRROR OPERATION

Turn the engine switch on (IG), and check the mirror operation.

NG -- REPLACE OUTER MIRROR CONTROL ECU

OK -- END

7. INSPECT OUTER MIRROR ACTUATOR ASSEMBLY

(a) Outer rear view mirror LH:

Disconnect the I3 connector.





(c) Apply battery voltage and check operation of the mirror face.

Standard:





(d) Outer rear view mirror RH:

Disconnect the H4 connector.





(f) Apply battery voltage and check operation of the mirror face.

Standard:





NG -- REPLACE OUTER MIRROR ACTUATOR ASSEMBLY Removal

OK -- REPLACE OUTER MIRROR CONTROL ECU
