Inspection 4: Vehicle Speed Signal

NGS0009S

1. 

CHECK VDC/TCS/ABS CONTROL UNIT

Perform self-diagnosis with VDC/TCS/ABS control unit. Refer to 

BRC-25, "DESCRIPTION"

 .

Is any malfunction detected by self-diagnosis?

YES

>> Check the malfunctioning system.

NO

>> GO TO 2.

2. 

CHECK RAS CONTROL UNIT CONNECTOR

1.

Turn ignition switch OFF, disconnect RAS control unit harness connector, and check terminal for deforma-
tion, disconnection, looseness, etc.

2.

Reconnect harness connector securely, and perform self-diagnosis.

With CONSULT-II

Without CONSULT-II

Is above displayed on self-diagnosis display?

YES

>> RAS control unit malfunction. Replace RAS control unit.

NO

>> Connector terminal connection is loose, damaged, open, or shorted. Repair or replace the termi-

nal.

Inspection 5: Steering Angle Signal Malfunction

NGS0009T

1. 

CHECK CONNECTOR

1.

Turn ignition switch OFF, disconnect RAS control unit harness connector and steering angle sensor har-
ness connector, and check terminal for deformation, disconnection, looseness, etc.

2.

Reconnect harness connector securely, and perform self-diagnosis.

With CONSULT-II

Without CONSULT-II

Is above displayed on self-diagnosis display?

YES

>> GO TO 2.

NO

>> Connector terminal connection is loose, damaged, open, or shorted. Repair or replace the termi-

nal.

2. 

ADJUST NEUTRAL POSITION OF STEERING ANGLE SENSOR

Adjust the steering angle sensor neutral position, and then perform self-diagnosis again. Refer to 

BRC-6,

"Adjustment of Steering Angle Sensor Neutral Position"

 .

Is the result of self-diagnosis normal?

OK

>> Inappropriate neutral position adjustment of steering angle sensor.

NG

>> GO TO 3.
