CHECK SLIDING SWITCH CIRCUIT HARNESS CONTINUITY
1. Disconnect driver seat control unit connector and power seat switch LH connector.
2. Check continuity between driver seat control unit connector B401 terminals 11, 26 and power seat switch LH connector B407 terminals 1, 7.
  11 - 7 : Continuity should exist.
  
  26 - 1 : Continuity should exist.
3. Check continuity between driver seat control unit connector B401 terminals 11, 26 and ground.
  11 - Ground : Continuity should not exist.
  
  26 - Ground : Continuity should not exist.
