Reverse Shift-Linked Function Of Power Mirrors Does Not Operate
MIRROR (EXT): 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
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 outer mirror reverse gear link switch is not ON.

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 CAN Communication System
A -- Continue to next step.
2. READ VALUE USING TECHSTREAM (PARK/NEUTRAL POSITION SWITCH)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream ON.
(d) Enter the following menus: Powertrain / ECT / Data List.
(e) According to the display on the Techstream, read the Data List.
ECT
OK:
On the Techstream screen, each item changes between ON and OFF according to above chart.
Result
E -- GO TO AUTOMATIC TRANSMISSION SYSTEM (PNP SWITCH CIRCUIT)
D -- GO TO AUTOMATIC TRANSMISSION SYSTEM (PNP SWITCH CIRCUIT)
C -- GO TO AUTOMATIC TRANSMISSION SYSTEM (PNP SWITCH CIRCUIT) P0705
B -- GO TO AUTOMATIC TRANSMISSION SYSTEM (PNP SWITCH CIRCUIT)
A -- Continue to next step.
3. READ VALUE USING TECHSTREAM (MIRROR POSITION SENSOR)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream ON.
(d) Enter the following menus: Body Electrical / Mirror / Data List.
(e) According to the display on the Techstream, read the Data List.
Mirror
OK:
When mirror control switch is operated to turn mirror upward or downward, voltage changes within range shown in above chart.
Result
D -- REPLACE OUTER MIRROR CONTROL ECU Disassembly
C -- CHECK OUTER MIRROR CONTROL ECU
B -- CHECK OUTER MIRROR CONTROL ECU
A -- Continue to next step.
4. INSPECT OUTER MIRROR REVERSE GEAR LINK SWITCH
(a) Remove the switch.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPLACE OUTER MIRROR REVERSE GEAR LINK SWITCH
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (OUTER MIRROR SWITCH - OUTER MIRROR CONTROL ECU)
(a) Disconnect the M8 ECU connector.
(b) Disconnect the H76 switch 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 MIRROR CONTROL ECU Disassembly
6. CHECK OUTER MIRROR CONTROL ECU
(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 Disassembly
OK -- Continue to next step.
7. CHECK HARNESS AND CONNECTOR (OUTER REAR VIEW MIRROR LH - OUTER MIRROR CONTROL ECU)
(a) Disconnect the M8 ECU connector.
(b) Disconnect the M5 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
8. CHECK OUTER MIRROR CONTROL ECU
(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 Disassembly
OK -- Continue to next step.
9. CHECK HARNESS AND CONNECTOR (OUTER REAR VIEW MIRROR RH - OUTER MIRROR CONTROL ECU)
(a) Disconnect the M8 ECU connector.
(b) Disconnect the L6 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
