Diagnostic Aids

WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.

DTC U0122:00 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 VDM concern.

Do not install a new PSCM as part of the repair for a PSCM DTC U0122:00.

The vehicle dynamic suspension has 3 settings; normal, comfort and sport. The PSCM uses the suspension status message from the VDM to adjust the steering feel to match the suspension feel. When DTC U0122:00 is present, the steering feel defaults to the normal setting.
