DTC C1963 [DSC/RSC]

id0402b3811900

Note
•  The initial point of the combined sensor (yaw rate sensor part) is corrected based on the signals from each sensor while the vehicle is driven straight, however, the correction cannot be performed if the vehicle is continuously driven on a curve and DTC C1963 is detected.

DTC
C1963
Combined sensor (Yaw rate sensor part) initial point correction error
DETECTION CONDITION
•  When a difference occurs between the estimated yaw rate value which is calculated by each sensor and the yaw rate value which is detected by the combined sensor (yaw rate sensor part).
POSSIBLE CAUSE
•  It occurs since the initial point correction for the combined sensor (yaw rate sensor part) cannot be performed due to the vehicle being continuously driven on a curve, and does not indicate an DSC/RSC system malfunction
•  DSC/RSC HU/CM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
PERFORM INITIALIZATION PROCEDURE
•  Perform the initialization procedure for the combined sensor.
After the initialization procedure for the combined sensor has been completed, go to the next step.
2
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Clear the DTC from the memory.
•  Start the engine and drive the vehicle at 72 km/h {45 mph}or more.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
If the malfunction occurs again, replace the DSC/RSC HU/CM, then go to the next step.
(See DSC/RSC HU/CM REMOVAL/INSTALLATION [L.H.D.].)
(See DSC/RSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
No
Go to the next step.
3
VERIFY AFTER REPAIR PROCEDURE
•  Are any other DTCs present?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSIS [DSC/RSC].)
No
DTC troubleshooting completed.
