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 steering wheel position for more than 30 seconds above 18 km/h (11 mph) or if driving aggressively immediately after turning the ignition on. This condition will most likely occur if there is some other DTC or if the vehicle reaches 75 km/h (47 mph) before confirming the straight-ahead position. 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 operation of PRNDL display and back-up lights).
• chassis modifications have been made that were not authorized by Ford.
• the vehicle is driven aggressively immediately after start-up.

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.
• A new stability assist module can have been installed in the vehicle and was not calibrated.
