Diagnostic Aids

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

DTC U0121:00 indicates that the ABS module cannot communicate over the HS-CAN bus. This could be due to a DTC being set in the ABS or a circuit fault in the HS-CAN bus. Do not install a new PSCM as part of the repair for a PSCM DTC U0121:00.
