CHECK PEDAL ADJUSTING SENSOR CIRCUIT HARNESS CONTINUITY
1. Disconnect automatic drive positioner control unit and pedal adjusting sensor.
2. Check continuity between automatic drive positioner connector M41, M42 terminals 8, 33, 41 and pedal adjusting sensor connector E110 terminals 1, 2, 3.
  8 - 2 : Continuity should exist.
  
  33 - 1 : Continuity should exist.
  
  41 - 3 : Continuity should exist.
3. Check continuity between automatic drive positioner control unit connector M41, M42 terminals 8, 33, 41 and ground.
  8 - Ground : Continuity should not exist.
  
  33 - Ground : Continuity should not exist.
  
  41 - Ground : Continuity should not exist.
OK or NG

OK: Replace pedal adjusting motor. Refer to "REMOVAL AND INSTALLATION ".

NG: Repair or replace harness.
