DTC C0051:62/C0051:64/C0051:67/C0051:85 [DYNAMIC STABILITY CONTROL (DSC)]

id0402b2906200

DTC
C0051:62, C0051:64, C0051:67, C0051:85
Steering angle sensor
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” and “Fail-safe function table”. (See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)].)
POSSIBLE CAUSE
•  C0051:62, C0051:64, C0051:67, C0051:85
―  Improper installation or positioning of the steering angle sensor
―  Steering angle sensor malfunction
―  DSC HU/CM malfunction
―  Connector or terminal malfunction
•  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 master warning light* illuminated?
Yes
Perform DTC inspection and go to the applicable DTC troubleshooting procedure.
(See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)].)
After completing the applicable DTC troubleshooting, go to the next step.
No
Clear the DTC from the memory and go to Step 3.
(See CLEARING DTC [DYNAMIC STABILITY CONTROL (DSC)].)
2
PERFORM EPS CM DTC INSPECTION
•  Perform the EPS CM DTC inspection.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS [ELECTRIC POWER STEERING (EPS)].)
No
Go to the next step.
3
VERIFY THAT THE SAME DTC IS NOT PRESENT
•  Clear the DTCs from the memory.
•  Start the engine and drive the vehicle at 20 km/h {12 mph} or more.
•  Are the same DTCs present?
Yes
Repeat the inspection from Step 1.
If the malfunction recurs, replace the DSC HU/CM, then go to the next step.
(See DSC HU/CM REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
(See DSC HU/CM REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
(See DSC HU/CM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
(See DSC HU/CM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
4
VERIFY THAT NO OTHER DTCS ARE PRESENT
•  Are any other DTCs output?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)].)
No
DTC troubleshooting completed.
