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 the PSCM sets this DTC power steering assist will be present, but active parking assist will be disabled.

The presence of DTC U0159:00 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.
