Title: MIRROR (EXT): POWER MIRROR CONTROL SYSTEM (w/ Memory): SYSTEM DESCRIPTION (2008 Sequoia) |
|
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.
