MIRROR (EXT)  POWER MIRROR CONTROL SYSTEM(w/ Memory)  Power Mirror Surface Position is not Memorized  


DESCRIPTION

If the M1 or M2 seat memory switch is pressed, the outer mirror control ECU assembly (driver door) detects the switch operation and sends the seat memory switch signal to the main body ECU (multiplex network body ECU) via CAN communication. On receiving the seat memory switch signal, the main body ECU (multiplex network body ECU) sends the memory request signal to each outer mirror control ECU assembly via CAN communication. When receiving this signal, each outer mirror control ECU assembly stores the mirror surface position based on information from the mirror position sensor, which is built into the outer rear view mirror assembly.

CAUTION / NOTICE / HINT

NOTICE:
·

The power mirror control system (w/ Memory) uses the CAN communication system. Inspect the communication functions by following How to Proceed with Troubleshooting. Troubleshoot the power mirror control system (w/ Memory) after confirming that the communication systems are functioning properly.

·

Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.

·

The mirror surface position will not be memorized if the ignition switch is not ON.

·

The mirror surface position will not be stored if the seat memory SET switch and 2 or more seat memory switches are pressed simultaneously.

·

If the operation fails, the mirror surface position will not be memorized until the seat memory SET switch is released and the operation is attempted again.

·

The mirror surface position will not be memorized when the mirror is operated manually.



HINT:

Each outer rear view mirror assembly has a built-in mirror vertical position sensor and mirror horizontal position sensor.
