Diagnostic Trouble Code (DTC) C1963

This Diagnostic Trouble Code DTC C1963 is stored if the stability assist warning indicator has been turned ON because the system can not confirm the straight-ahead position for more than 30 seconds above 18 km/h (11 mph) or if the vehicle reaches 75 km/h (47 mph) before confirming the straight-ahead position. This condition most likely occurs if there is some other DTC or from driving aggressively immediately after turning the ignition on. If there is another DTC logged, the repair procedure is to follow the procedure for the first DTC. DTC C1963 can be stored if:

• the PRNDL or REVERSE switch has failed (check the operation of the PRNDL display and the back-up lights).
• unauthorized chassis modifications are made.

In very rare circumstances this DTC C1963 can be stored by itself without the occurrence of any actual component failure. The following conditions can cause DTC C1963 to set with no other DTC:

• The steering wheel is turned while the ignition switch is off and then the vehicle is started, and either the vehicle is driven continuously in a circle or the vehicle is driven with continuous swerving, sliding or tire spinning.
• An uncalibrated stability assist module is installed in the vehicle.
