DTC C0051:62/C0051:64/C0051:67/C0051:85 [DSC HU/CM]

DTC

C0051:62

EPS control module

C0051:64

C0051:67

C0051:85

DETECTION CONDITION

•  C0051:62

―  The difference between the steering angle calculated by each sensor and the steering angle from the steering angle sensor is the specification or more when the vehicle is driven in a straight line

•  C0051:64

―  The difference between the steering angle calculated by each sensor and the steering angle from the steering angle sensor exceeds the specification

•  C0051:67

―  The neutral position of the steering angle cannot be estimated from the signals from the ABS wheel-speed sensors and the SAS control module

Note

•  Each time the ignition is switched ON, the DSC HU/CM calculates the steering angle neutral position based on the signals from each sensor and each module.

•  If the vehicle is driven as follows just after the engine is started, DTC C0051:67 may be output.

―  Vehicle is accelerated rapidly while being steered right or left

―  Vehicle is driven on abnormal road surface such as banked road

―  Vehicle is driven on continuously curved road such as mountain road

•  If the DTC is a past malfunction during DTC inspection, it does not indicate a vehicle malfunction.

•  C0051:85

―  The steering angle sensor detects signal modulation or steering angle that exceeds specification

FAIL-SAFE FUNCTION

Refer to DTC TABLE. (See DTC TABLE [DSC HU/CM].)

POSSIBLE CAUSE

•  C0051:62, C0051:64, C0051:85

―  Improper installation or positioning of the steering angle sensor

―  Steering angle sensor malfunction

―  Poor connection at each connector

•  C0051:67

―  Vehicle is accelerated rapidly while being steered right or left

―  Vehicle is driven on abnormal road surface such as banked road

―  Vehicle is driven on continuously curved road such as mountain road

Diagnostic Procedure

Step

Inspection

Action

1

VERIFY WHETHER MALFUNCTION IS PAST OR PRESENT

•  Switch the ignition ON (engine off or on).

•  Is the TCS/DSC indicator light illuminated?

Yes

Go to applicable DTC inspection.

(See DTC INSPECTION [DSC HU/CM].)

DTC troubleshooting completed, then go to the next step

No

Clear the DTC from the memory and go to the Step3.

(See CLEARING DTC [DSC HU/CM].)

2

VERIFY EPS CONTROL MODULE DTC

•  Using the M-MDS, perform the EPS control module DTC inspection.
(See DTC INSPECTION [EPS CONTROL MODULE].)

•  Are any DTCs present?

Yes

Go to applicable DTC inspection.

(See DTC TABLE [EPS CONTROL MODULE].)

DTC troubleshooting completed, then go to the next step.

No

Go to the next step.

3

VERIFY DTC TROUBLESHOOTING COMPLETED

•  Using the M-MDS, clear the DTC from the DSC HU/CM.
(See CLEARING DTC [DSC HU/CM].)

•  Start the engine and drive the vehicle at 20 km/h {12 mph} or more.

•  Using the M-MDS, perform the DSC HU/CM DTC inspection.
(See DTC INSPECTION [DSC HU/CM].)

•  Is the same DTC present?

Yes

Repeat the inspection from Step1

If the malfunction recurs, replace the DSC HU/CM, then go to the next step.

(See DSC HU/CM REMOVAL/INSTALLATION [L.H.D.].)

(See DSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)

No

Go to the next step.

4

VERIFY NO DTC IS PRESENT

•  Are any DTCs present?

Yes

Go to applicable DTC inspection.

(See DTC TABLE [DSC HU/CM].)

No

DTC troubleshooting completed.
