Diagnostic Aids

DTC U0001:88 indicates a failure of the HS-CAN which can be due to a circuit failure in the HS-CAN or the PSCM wiring harness.

When this DTC is set, steering assist is reduced but not removed.

The presence of DTC U0001:88 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.
