Driving Position Memory Switch Circuit (w/ Memory)
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 tu ...
