TILT SWITCH
DescriptionINFOID:0000000003775569
ADP steering switch is equipped to the steering column. The operation signal is input to the automatic drive
positioner control unit when the ADP steering switch is operated.
Component Function CheckINFOID:0000000003775570
1. CHECK FUNCTION
1. Select “TILT SW-UP”, “TILT SW-DN” in “Data monitor” mode with CONSULT-III.
2. Check tilt switch signal under the following conditions.
Is the indication normal?
YES >> Inspection End.
NO >> Perform diagnosis procedure. Refer to ADP-57, "Diagnosis Procedure"
.
Diagnosis ProcedureINFOID:0000000003775571
1. CHECK ADP STEERING SWITCH SIGNAL
1. Turn ignition switch OFF.
2. Check voltage between automatic drive positioner control unit
connector and ground.
Is the inspection result normal?
YES >> GO TO 4
NO >> GO TO 2
2. CHECK ADP STEERING SWITCH HARNESS CONTINUITY
1. Disconnect automatic drive positioner control unit and ADP steering switch.
2. Check continuity between automat ic drive positioner control unit
connector M33 terminals 1, 17 and ADP steering switch connec-
tor M16 terminals 2, 3.
3. Check continuity between automat ic drive positioner control unit
connector M33 terminals 1, 17 and ground.

TILT SENSOR
TILT SENSOR
DescriptionINFOID:0000000003775609
 The tilt sensor is installed to the steering column assembly.
 The resistance of tilt sensor is changed according to the up/down position of steering column.
 The terminal voltage of automatic drive positioner c ontrol unit will be changed according to a change of tilt
sensor resistance. Automatic drive positioner contro l unit calculates the tilt position from the voltage.
Component Function CheckINFOID:0000000003775610
1. CHECK FUNCTION
1. Select “TILT SEN” in “Data monitor” mode with CONSULT-III.
2. Check the tilt sensor signal under the following condition.
Is the indication normal?
YES >> Inspection End.
NO >> Perform diagnosis procedure. Refer to ADP-82, "Diagnosis Procedure"
.
Diagnosis ProcedureINFOID:0000000003775611
1. CHECK TILT SENSOR SIGNAL
1. Turn ignition switch OFF.
2. Check voltage between automatic drive positioner connector and ground.
Is the inspection result normal?

TILT MOTOR
TILT MOTOR
DescriptionINFOID:0000000003775633
 The tilt motor is installed to the steering column assembly.
 The tilt motor is activated with the automatic drive positioner control unit.
 The steering column is tilted upward/downward by changing the rotation direction of tilt motor.
Component Function CheckINFOID:0000000003775634
1. CHECK FUNCTION
1. Select “TILT MOTOR” in “Act ive test” mode with CONSULT-III.
2. Check the tilt motor operation.
Is the operation of relevant parts normal?
YES >> Inspection End.
NO >> Perform diagnosis procedure. Refer to ADP-98, "Diagnosis Procedure"
.
Diagnosis ProcedureINFOID:0000000003775635
1. CHECK TILT MOTOR HARNESS CONTINUITY
