Headrest Motor and Position Sensor Circuit (RH)

HEADREST MOTOR AND POSITION SENSOR CIRCUIT (RH)

CIRCUIT DESCRIPTION

The position sensor detects seat movement and sends pulse signals to the rear RH seat ECU for use with the memory function.

The position sensor sends pulses to the ECU in proportion to the amount of seat movement. The ECU records the number of pulses relative to a previously recorded seat position and uses this data to return the seat to that position.

If a malfunction occurs in a position sensor and seat movement does not result in pulse signals being input into the ECU, the ECU deactivates the memory function.
