Check for continuity between body ground (motor body) and the No. 3 terminal of the front up-down motor/position sensor, rear up-down motor/position sensor, and recline motor/position sensor.
Is there continuity?
YES
-
If the front or rear up-down motor/position sensor is faulty, replace the seat frame assembly. If the recline motor/position sensor is faulty, replace the recline motor/position sensor.■
