SYSTEM DESCRIPTION
On receiving a reverse signal from the park/neutral position switch assembly, the ECM sends the reverse signal to the main body ECU (driver side junction block assembly) via CAN communication. When receiving the reverse signal, the main body ECU (driver side junction block assembly) sends the reverse request signal to each outer mirror control ECU. Each outer mirror control ECU then performs control in response to the reverse signal.
HINT:
The reverse shift-linked function will not activate when the mirror select switch is in the neutral position (off).

PROCEDURE
1. |
CHECK MEMORY AND REACTIVATION FUNCTION |
(a) Turn the ignition switch ON. |
|
(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.

CHECK FOR DTC |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / DTC.
(e) Check if SFI system DTCs are output.
OK:
SFI system DTCs are not output.

4. |
CHECK COMBINATION METER ASSEMBLY |
(a) Check if the shift position indicator light in the combination meter assembly operates normally.
OK:
The shift position indicator light indicates the actual shift position correctly.

5. |
CHECK REVERSE SHIFT-LINKED FUNCTION |
(a) Turn the ignition switch ON. |
|
(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 |
