Front Power Seat does not Operate with Front Power Seat Switch

Signals are input into the position control ECU and switch assembly. The built-in ECU manages the signals received from the position control ECU and switch assembly, and operates each motor. If the position control ECU and switch assembly receives more than 2 motor operation signals, the motor is stopped. Manual operation is restarted after the position control ECU and switch assembly receives 1 signal only.

NOTICE:

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

1. CHECK FRONT POWER SEAT OPERATION

(a) Check that each function of the power seat operates normally by using the position control ECU and switch assembly (See page ).
