DESCRIPTION
The seat memory switch sends signals to the outer mirror control ECU LH via the multiplex communication system to memorize a given seat position. This memory system does not use a position sensor. The seat position is detected by counting pulses that are output when the motor turns. If there is no pulse output from the motor, the motor will stop operating. The seat memory switch is later used to send signals to the front power seat switch to return the seat to one of the memorized positions.
The power seat memory operation can be performed only when the ignition switch is on and the shift lever is in the P position.
