CHECK LIFTING MOTOR (FRONT) SENSOR CIRCUIT HARNESS CONTINUITY
1. Disconnect driver seat control unit and lifting motor (front).
2. Check continuity between driver seat control unit connector P2 terminals 16, 25, 31 and lifting motor (front) connector P6 terminals 1, 2, 3.
  16 (W) - 3 (W) : Continuity should exist .
  
  25 (LG) - 2 (LG) : Continuity should exist .
  
  31 (L/Y) - 1 (L/Y) : Continuity should exist .
3. Check continuity between driver seat control unit connector P2 terminals 16, 25, 31 and ground.
  16 (W) - Ground : Continuity should not exist .
  
  25 (LG) - Ground : Continuity should not exist .
