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
* for AT:
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 assembly via the CAN and BEAN communication system. The outer mirror control ECU assembly activates the response to the reverse signal.
* for MT:
The main body ECU LH (cowl side junction block LH) detects the condition of the back up light switch. The main body ECU LH (cowl side junction block LH) also sends a back up light switch signal to the outer mirror control ECU assembly via the BEAN communication system. The outer mirror control ECU assembly controls the reverse shift-linked function based on the back up light switch signal.
HINT
The reverse shift-linked function will not activate when the mirror select switch is in the neutral position (off).

INSPECTION PROCEDURE
PROCEDURE
1. CHECK MULTIPLEX COMMUNICATION SYSTEM
(a) Use the Techstream to check if the multiplex communication system is functioning normally How To Proceed With Troubleshooting.
OK:
Multiplex communication DTC is not output.
NG -- GO TO MULTIPLEX COMMUNICATION SYSTEM Multiplex Communication System
OK -- Continue to next step.
2. CHECK REVERSE SHIFT-LINKED FUNCTION
(a) Turn the engine switch on (IG).
(b) Set the mirror select switch to L or R.
(c) Check that the mirror surface turns downward when the shift lever is moved to R.
Result:
B -- CHECK BACK UP LIGHT FUNCTION
C -- CHECK MEMORY AND REACTIVATION FUNCTION
A -- Continue to next step.
3. CHECK CAN COMMUNICATION SYSTEM
(a) Use the Techstream to check if the CAN communication system is functioning normally How to Proceed With Troubleshooting.
OK:
CAN communication DTC is not output.
NG -- GO TO CAN COMMUNICATION SYSTEM How to Proceed With Troubleshooting
OK -- Continue to next step.
4. CHECK FOR DTC (P0705)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / DTC.
(e) Check if DTC P0705 is output.
Result:
B -- GO TO AUTOMATIC TRANSMISSION SYSTEM (for A760E) P0705
C -- GO TO AUTOMATIC TRANSMISSION SYSTEM (for A960E)
A -- Continue to next step.
5. READ VALUE USING TECHSTREAM
(a) Enter the following menus: Chassis / ABS/VSC / Data List.
(b) Read the Data List according to the display on the Techstream.
ABS/VSC/TRAC
Result:
B -- REPLACE ECM (for 2GR-FSE) Removal
C -- REPLACE ECM (for 4GR-FSE) Removal
A -- REPLACE NETWORK GATEWAY ECU Removal
6. CHECK BACK UP LIGHT FUNCTION
(a) Move the shift lever to R and check if the back up lights come on.
OK:
The back up lights come on.
NG -- GO TO LIGHTING SYSTEM Exterior Lighting System
OK -- Continue to next step.
7. READ VALUE USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Body No. 3 / Data List.
(e) Read the Data List according to the display on the Techstream.
Body No. 3
NG -- CHECK HARNESS AND CONNECTOR
OK -- REPLACE MAIN BODY ECU LH (COWL SIDE JUNCTION BLOCK LH)
8. CHECK HARNESS AND CONNECTOR
(a) Disconnect the E55 and LJ connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Text in Illustration
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE MAIN BODY ECU LH (COWL SIDE JUNCTION BLOCK LH)
9. CHECK MEMORY AND REACTIVATION FUNCTION
(a) Turn the engine switch on (IG).
(b) Using the outer mirror switch assembly, turn the mirror surface to the fully left position.
(c) Press the M1 switch while the SET switch is being pressed.
(d) Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized.
(e) Using the outer mirror switch assembly, turn the mirror surface to the fully right position.
(f) Press the M1 switch.
(g) Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully left position.
OK:
Memory and reactivation function is normal.

NG -- GO TO OTHER FLOW CHART (Power Mirrors do not Return to Memorized Position) Power Mirrors Do Not Return To Memorized Position
OK -- REPLACE OUTER MIRROR CONTROL ECU ASSEMBLY Removal
