Pedal Adjusting Switch Circuit Inspection

WARNING: This page is about a different car, the 2006 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FUNCTION

With CONSULT-II

With "PEDAL SW-FR, PEDAL SW-RR" on the DATA MONITOR, operate the pedal adjusting switch to check ON/OFF operation.

CONSULT-II FUNCTION

Monitor item [OPERATION or UNIT]		Contents
PEDAL SW-FR	"ON/OFF"	Operation (ON)/open (OFF) status judged from the pedal adjusting switch (FR) signal is displayed.
PEDAL SW-RR	"ON/OFF"	Operation (ON)/open (OFF) status judged from the pedal adjusting switch (RR) signal is displayed.

Fig 1: CONSULT-II Display - DATA MONITOR

Without CONSULT-II

Turn ignition switch OFF.

Check voltage between driver seat control unit connector and ground.

OK or NG

OK : Pedal adjusting switch circuit is OK.

NG : GO TO 2.

CHECK PEDAL ADJUSTING SWITCH CIRCUIT HARNESS CONTINUITY
1. Disconnect driver seat control unit and pedal adjusting switch.
2. Check continuity between driver seat control unit connector P2 terminals 15, 30 and pedal adjusting switch connector M96 terminals 2, 3.
  15 - 2 : Continuity should exist.
  
  30 - 3 : Continuity should exist.
3. Check continuity between driver seat control unit connector P2 terminals 15, 30 and ground.
  15 - Ground : Continuity should not exist.
  
  30 - Ground : Continuity should not exist.
