DTC C1963

This diagnostic trouble code (DTC) is stored if the stability assist warning indicator has been turned ON because the system could 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 will most likely occur 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. This DTC can be stored if:

• the PRNDL or REVERSE switch has failed (check the operation of the PRNDL display and the backup lights).
• Unauthorized chassis modifications have been made.

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

  • The steering wheel has been turned while the ignition 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 has been installed in the vehicle.
