Diagnostic Aids

DTC U0401:68 indicates an brake pedal position, engine speed, transmission gear or vehicle speed 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. When this DTC is set, steering assist is reduced resulting in higher steering efforts during low speed maneuvers.
