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

ECM sends the reverse signal to the main body ECU (multiplex network body ECU) via CAN communication. When receiving the reverse signal, the main body ECU (multiplex network body ECU) sends the reverse request signal to each outer mirror control ECU assembly. Each outer mirror control ECU assembly then performs control in response to the reverse signal.

INSPECTION PROCEDURE

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

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

(a) Check if a CAN communication DTC is output Diagnosis System.
