POWER MIRROR CONTROL SYSTEM (w/ Memory) 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 assembly, the outer mirror control ECU assembly activates the reverse shift-linked function of the outer rear view mirrors assembly LH and RH.

Tech Tips

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