Check Tilt Sensor Circuit

CHECK TILT STEERING MECHANISM
Check the operation malfunction caused by steering wheel tilt mechanism deformation or parts are loose.

OK or NG
- OK : GO TO 2.
- NG : Repair the malfunctioning part and check again.

CHECK FUNCTION

With CONSULT-II

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

MONITOR ITEM AND CONTENTS REFERENCE

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

Without CONSULT-II

Turn ignition switch OFF.

Check voltage between BCM connector and ground.

CONNECTORS VOLTAGE REFERENCE

Connector	Terminals (Wire color)		Condition	Voltage (V) (Approx.)
Connector	(+)	(-)	Condition	Voltage (V) (Approx.)
M4	46 (L/R)	Ground	Tilt top position	2
M4	46 (L/R)	Ground	Tilt bottom position	4

OK or NG

OK : System is OK.
NG : GO TO 3.

CHECK HARNESS
1. Disconnect BCM connector and tilt sensor connector.
2. Check continuity harness between BCM connector M4 terminals 46, 53, 54 and tilt sensor connector M57 terminals 1, 2, 3.
  46 (L/R) - 2 (L/R) : Continuity should exist.
  
  53 (L/W) - 3 (L/W) : Continuity should exist.
  
  54 (B/Y) - 1 (B/Y) : Continuity should exist.
3. BCM connector M4 terminals 46, 53, 54 and ground.
  46 (L/R) - Ground : Continuity should not exist.
  
  53 (L/W) - Ground : Continuity should not exist.
  
  54 (B/Y) - Ground : Continuity should not exist.
OK or NG
- OK : Replace tilt sensor.
- NG : Repair or replace harness between BCM and tilt sensor.
