Check Telescopic Sensor Circuit

1. CHECK FUNCTION 

   With CONSULT-III 

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

   TELESCO SEN	"V"	The telescoping position (voltage) judged from the telescoping sensor signal is displayed.

   Without CONSULT-III 

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

   Connector	Terminals (Wire color)		Condition	Voltage (V) (Approx.)
   	(+)	(-)
   M49	23 (Y/B)	Ground	Telescopic top position	1
   			Telescopic bottom position	4

   OK or NG 

   OK: Telescopic sensor circuit is OK.

   NG: GO TO 2.

2. CHECK HARNESS CONTINUITY 
   1. Disconnect automatic drive positioner control unit connector and tilt sensor and telescopic sensor connector.
   2. Check continuity harness between automatic drive positioner control unit connector M49 terminals 23 and tilt sensor and telescopic sensor connector M28 terminals 3.

      23 (Y/B) - 3 (Y/B) : Continuity should exist. 

   3. Check continuity harness between automatic drive positioner control unit connector M49 terminals 23 and ground.

      23 (Y/B) - Ground : Continuity should not exist.

OK or NG 

OK: Replace tilt sensor and telescopic sensor.

NG: Repair or replace harness between automatic drive positioner control unit and tilt sensor and telescopic sensor.
