DTC U053B:00 indicates a concern with the lane information sent from the IPM-A. The module reporting this DTC is not the problem module. Do not install a new PSCM as part of the repair for PSCM DTC U053B:00. The presence of DTC U053B:00 prevents the lane keep assist system (if equipped) from activating. If set during a lane keep event, the event is terminated and the lane keep assist system is deactivated.
