Diagnostic Aids

WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

DTC U0401:68 indicates an engine speed, vehicle speed or tire size message concern. The module reporting this DTC is not the problem module. Do not install a new PSCM as part of the repair for PSCM DTC U0401:68. If the vehicle speed signal is the cause of the concern the vehicle speed sets to a default value, if the wheel speed or tire size message is the cause of the concern the Active Nibble assistance is disabled.
