Telescopic Sensor Circuit Inspection

WARNING: This page is about a different car, the 2008 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FUNCTION

With CONSULT-III

Operate the ADP steering switch with "TELESCO SEN" on the DATA MONITOR to make sure the voltage changes.

TELESCO SEN MONITOR ITEM CHART

Monitor item [OPERATION or UNIT]		Contents
TELESCO SEN	"V"	The telescopic position (voltage) judged from the telescopic sensor signal is displayed.

Without CONSULT-III

Turn ignition switch OFF.

Check voltage between automatic drive positioner connector and ground.

AUTOMATIC DRIVE POSITIONER CONNECTOR AND GROUND

Connector	Terminals		Condition	Voltage (V) (Approx.)
Connector	(+)	(-)	Condition	Voltage (V) (Approx.)
M41	23	Ground	Telescopic front end position	2
M41	23	Ground	Telescopic back end position	4

OK or NG

OK: Telescopic sensor circuit is OK.

NG: GO TO 2.

CHECK HARNESS CONTINUITY
1. Disconnect automatic drive positioner control unit and steering wheel telescopic sensor.
2. Check continuity between automatic drive positioner connector M41, M42 terminals 23, 33, 41 and telescopic sensor connector M67 terminals 1,2, 3.
  23 - 2: Continuity should exist.
  
  33 - 1: Continuity should exist.
  
  41 - 3: Continuity should exist.
3. Check continuity between automatic drive positioner control unit connectors M41, M42 terminals 23, 33, 41 and ground.
  23 - Ground: Continuity should not exist.
  
  33 - Ground: Continuity should not exist.
  
  41 - Ground: Continuity should not exist.
