Diagnostic Aids
DTC U0122:00 indicates that the VDM cannot communicate over the HS-CAN bus. This could be due to a DTC being set in the VDM or a circuit fault in the HS-CAN bus. 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.
