DESCRIPTION
When the seat memory SET switch and a memory switch (M1 or M2) are pressed simultaneously, the main body ECU commands the position control ECU through CAN communication to record the value of each position sensor.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
The front power seat control system (w/ Memory) uses the CAN communication system.
First, confirm that there are no malfunctions in the communication system by checking
the communication function of the CAN communication system (See page
).
PROCEDURE
1. |
CHECK FRONT POWER SEAT CONTROL FUNCTION |
(a) Check that each function of the power seat operates normally by using the
front power seat switches (See page ).
OK:
Each function of power seat operates normally by using seat switches.
