WARNING: This page is about a different car, the 2020 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets when the actual vehicle deceleration monitored by the ABS module exceeds the CCM deceleration maximum request limit by 1.0 meter per second squared. The CCM sends the message to the IPMA over a private CAN, the IPMA then sends the message to the ABS module over the HS-CAN2. RETRIEVE and DIAGNOSE all CCM and IPMA DTCs REFER to the appropriate Cruise Control article and the Rear View Mirrors article.
