DTC C0051:54 [DYNAMIC STABILITY CONTROL (DSC)]

id0402b2882000

Note

• The steering angle initialization value of the BCM is stored using the battery power supply. Therefore, the battery power supply of the BCM is cut and the stored steering angle initialization value is cleared when any of the following items are performed.

― Negative battery cable disconnection

― BCM connector disconnection

― Fuse (ROOM) removal

― Wiring harness disconnection between battery, BCM connector, steering angle sensor connector

DTC

C0051:54

Steering angle sensor (abnormal initialization) system

DETECTION CONDITION

•  The steering angle sensor detects that the initialization procedure has not been performed.

POSSIBLE CAUSE

•  The initialization procedure for the steering angle sensor has not been performed.

•  Steering angle sensor malfunction

•  BCM malfunction

•  The negative battery cable connector was disconnected previously.

•  The steering angle sensor connector was disconnected previously.

•  The BCM connector was disconnected previously.

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY INITIALIZATION PROCEDURE. • Has the steering angle sensor initialization procedure been performed?	Yes	Go to the next step.
1		No	Perform the steering angle sensor initialization procedure, then go to Step 3. (See STEERING ANGLE SENSOR INITIALIZATION PROCEDURE.)
2	INSPECT FOR BCM MALFUNCTION • Switch the ignition to off. • Using the M-MDS, perform the DTC inspection for the BCM. (See DTC INSPECTION [BCM].) • Are any DTCs detected?	Yes	Go to applicable DTC inspection. (See DTC TABLE [BCM].)
2		No	Go to the next step.
3	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction occurs again, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION.)
3		No	Go to the next step.
4	VERIFY AFTER REPAIR PROCEDURE • Are any other DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
4		No	DTC troubleshooting completed.
