Diagnostic Aids

DTC U0140:00 indicates a possible failure of the HS-CAN which can be due to a circuit fault in the HS-CAN, the PSCM wiring harness or a BCM concern.

Do not install a new PSCM as part of the repair for a PSCM DTC U0140:00.

The presence of DTC U140:00 prevents the active park assist system (if equipped) and the lane keep assist function (if equipped) from activating. If set during an active park assist event, the event is terminated and the active park assist system is deactivated.
