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

id040262906200

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).
•  Are the TCS/DSC indicator light and the Smart Brake Support/Smart City Brake Support (SBS/SCBS) indicator light (amber)* 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.
•  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.
•  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.
•  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.
