ADP Steering Telescopic Switch 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

With "TELESCO SW-FR, TELESCO SW-RR" on the DATA MONITOR, operate the ADP steering telescopic switch to check ON/OFF operation.

TELESCO SW MONITOR ITEM CHART

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

Without CONSULT-III

Turn ignition switch OFF.
Check voltage between automatic drive positioner control unit connector and ground.

AUTOMATIC DRIVE POSITIONER CONTROL UNIT CONNECTOR AND GROUND

Connector	Terminals		Condition	Voltage (V) (Approx.)
Connector	(+)	(-)	Condition	Voltage (V) (Approx.)
M41	11	Ground	Telescopic switch ON (FORWARD operation)	0
	11		Other than above	5
	27		Telescopic switch ON (BACKWARD operation)	0
	27		Other than above	5

OK or NG

OK: ADP steering telescopic switch circuit is OK.

NG: GO TO 2.

CHECK ADP STEERING TELESCOPIC SWITCH HARNESS CONTINUITY
1. Disconnect automatic drive positioner control unit and ADP steering switch.
2. Check continuity between automatic drive positioner control unit connector M41 terminals 11, 27 and ADP steering switch connector M16 terminals 4, 5.
  11 - 5: Continuity should exist.
  
  27 - 4: Continuity should exist.
3. Check continuity between automatic drive positioner control unit connector M41 terminals 11, 27 and ground.
  11 - Ground: Continuity should not exist.
  
  27 - Ground: Continuity should not exist.
