CHECK SLIDING MOTOR SENSOR CIRCUIT HARNESS CONTINUITY
1. Disconnect driver seat control unit connector and sliding motor LH.
2. Check continuity between driver seat control unit connector P2 terminals 16, 24, 31 and sliding motor P4 terminals 1,2,3.
  - 16 (W) - 3 (W): Continuity should exist.
  - 24 (Y/G) - 2 (Y/G): Continuity should exist.
  - 31 (L/Y) - 1 (L/Y): Continuity should exist.
3. Check continuity between driver seat control unit P2 terminals 16, 24, 31 and ground.
  - 16 (W) - Ground: Continuity should not exist.
  - 24 (Y/G) - Ground: Continuity should not exist.
