Diagnostic Aids

DTC U0126:00 indicates that the steering angle sensor module cannot communicate over the HS-CAN bus. This could be due to a DTC being set in the module or there is a circuit fault in the HS-CAN bus. Do not install a new PSCM as part of the repair for a PSCM U0126:00.

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

The presence of DTC U0126:00 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.
