OK or NG

OK : Sliding sensor circuit is OK.
NG : GO TO 2.

CHECK SLIDING SENSOR CIRCUIT HARNESS CONTINUITY
1. Disconnect driver seat control unit connector and sliding motor connector.
2. Check continuity between driver seat control unit connector B303 terminals 24 (G/B), 31 (R/W) and sliding motor B307 terminals 24 (G/B), 31A (R/W).
  1. 24 (G/B) - 24 (G/B): Continuity should exist.
  2. 31 (R/W) - 31A (R/W): Continuity should exist.
3. Check continuity between driver seat control unit B303 terminals 24 (G/B), 31 (R/W) and ground.
  1. 24 (G/B) - Ground: Continuity should not exist.
  2. 31 (R/W) - Ground: Continuity should not exist.
