OK or NG

OK: Pedal adjusting sensor circuit is OK.
NG: GO TO 2.

CHECK PEDAL ADJUSTING SENSOR CIRCUIT HARNESS CONTINUITY
1. Disconnect automatic drive positioner control unit and pedal adjusting sensor connector.
2. Check continuity between automatic drive positioner connector M19, M20 terminals 8 (P/B), 33 (W/L), 41 (Y) and pedal adjusting sensor connector E114 terminals 3 (Y), 4 (P/B), 5 (W/L).
  8 (P/B) - 4 (P/B): Continuity should exist.
  
  33 (W/L) - 5 (W/L): Continuity should exist.
  
  41 (Y) - 3 (Y): Continuity should exist.
3. Check continuity between automatic drive positioner control unit connector E114 terminals 8 (P/B), 33 (W/L), 41 (Y) and ground.
  8 (P/B) - Ground: Continuity should not exist.
  
  33 (W/L) - Ground: Continuity should not exist.
  
  41 (Y) - Ground: Continuity should not exist.
OK or NG
1. OK: Replace pedal adjusting motor.
2. NG: Repair or replace harness between automatic drive positioner and pedal adjusting sensor.
