DTC U2107: Collision Mitigation By Braking: Action
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets when the collision deceleration message from the CCM is sent too often or the duration of the message is too long. 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. This concern is most likely caused by a network communication concern, an internal failure of the CCM, or an internal failure of the IPMA. RETRIEVE and DIAGNOSE all DTCs in the CCM and IPMA. REFER to the appropriate Cruise Control article and REAR VIEW MIRRORS .
