Diagnostic Aids

WARNING: This page is about a different car, the 2014 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

DTC U023A:00 indicates that the IPM-A cannot communicate over the HS-CAN bus. This could be due to a DTC being set in the IPMA or a circuit fault in the HS-CAN bus. Do not install a new PSCM as part of the repair for a PSCM DTC U023A:00. When DTC U023A:00 is present, the lane keeping assist function (if equipped) is disabled.
