Check Tilt Sensor Circuit

1. CHECK TILT SENSOR 

   With CONSULT-III 

   With "TILT SEN" on the DATA MONITOR, operate the tilt switch to make sure voltage changes.

   TILT SEN	"V"	The tilt position (voltage) judged from the tilt 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	7 (Y/R)	Ground	Tilt top position	2
   			Tilt bottom position	4

   OK or NG 

   OK: Tilt sensor circuit is OK.

   NG: GO TO 2.

2. CHECK HARNESS 
   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 7 and tilt sensor and telescopic sensor connector M28 terminals 2.

      7 (Y/R) - 2 (Y/R) : Continuity should exist. 

   3. Check continuity harness between automatic drive positioner control unit connector M49 terminals 7 and ground.

      7 (Y/R) - 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.
