Diagnostic Aids

DTC U0159:00 indicates that the parking assist control module cannot communicate over the HS-CAN bus, which could be due to a DTC being set in the module or a circuit fault in the HS-CAN bus. Do not install a new PSCM as part of the repair for a PSCM U0159:00.

When this DTC is set steering assist is unaffected and active park assist is disabled (if equipped).

The presence of DTC will prevent the active park assist system (if equipped) from activating. If set during an active park assist event, the event will be terminated and the active park assist system will deactivate.
