OK or NG

OK: Sliding sensor circuit is OK.

NG: GO TO 2.

CHECK SLIDING SENSOR HARNESS CONTINUITY 1
1. Disconnect driver seat control unit and sliding motor LH.
2. Check continuity between driver seat control unit connector B401 (A) terminals 16, 31 and sliding motor LH connector B404 (B) terminals 4, 6.
  16 - 6: Continuity should exist.
  
  31 - 4: Continuity should exist.
3. Check continuity between driver seat control unit connector B401 (A) terminals 16, 31 and ground.
  16 - Ground: Continuity should not exist.
  
  31 - Ground: Continuity should not exist.
