Power Seat Position Is Not Memorized

Power Seat Position is not Memorized

DESCRIPTION
The driver side seat memory switch sends signals to the position control ECU LH to memorize given seat position via the multiplex network master switch assembly. The passenger side seat memory switch signals the position control ECU RH to memorize a given seat position via the front multiplex network door ECU RH. This memory system does not use a seat 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 sends signals to the position control ECU to return to one of the memorized positions.
