Diagnostic Aids

DTC U0126:00 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 SASM concern.

Do not install a new PSCM as part of the repair for a PSCM DTC U0126:00.

When the PSCM sets this DTC power steering assist is present, but active park assist is disabled. Steering wheel returnability during slow speed maneuvering may be reduced.

The presence of DTC U0126:00 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.
