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

SYSTEM DESCRIPTION

When the reverse signal is sent from the ECM through the CAN communication line to the outer mirror control ECU, the outer mirror control ECU activates the outer rear view mirror LH and RH reverse shift-linked function.

HINT
The reverse shift-linked function will not occur when the mirror master switch is in the neutral position (off).

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC

(a) Use the Techstream to check if the CAN communication system is functioning normally Diagnosis System.

Result





B -- GO TO CAN COMMUNICATION SYSTEM Diagnosis System
A -- Continue to next step.

2. CHECK OPERATION OF SHIFT INDICATOR

(a) Check that the shift indicator of the combination meter operates normally.

OK:

Shift indicator of combination meter operates normally.

OK -- Continue to next step.

3. READ VALUE USING TECHSTREAM (MIRROR POSITION SENSOR)

(a) Check the Data List for proper functioning of the mirror position sensor Scan Tool Testing and Procedures.

Mirror





OK:

When mirror control switch is operated to turn mirror upward or downward, voltage changes within range shown in above chart.

Result





C -- REPLACE OUTER MIRROR CONTROL ECU Removal

B -- CHECK OUTER MIRROR CONTROL ECU (POWER SOURCE FOR MIRROR POSITION SENSOR)
A -- Continue to next step.

4. CHECK OUTER MIRROR CONTROL ECU (POWER SOURCE FOR MIRROR POSITION SENSOR)





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

Standard Voltage:





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

Standard Resistance:





NG -- REPLACE OUTER MIRROR CONTROL ECU Removal
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (OUTER REAR VIEW MIRROR LH - OUTER MIRROR CONTROL ECU)

(a) Disconnect the I18 ECU connector.





(b) Disconnect the I15 mirror connector.

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

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY LH Removal

6. CHECK OUTER MIRROR CONTROL ECU (POWER SOURCE FOR MIRROR POSITION SENSOR)





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

Standard Voltage:





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

Standard Resistance:





NG -- REPLACE OUTER MIRROR CONTROL ECU Removal
OK -- Continue to next step.

7. CHECK HARNESS AND CONNECTOR (OUTER REAR VIEW MIRROR RH - OUTER MIRROR CONTROL ECU)

(a) Disconnect the I18 ECU connector.





(b) Disconnect the I7 mirror connector.

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

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY RH Removal
