Normal Operation and Fault Conditions

With the ignition ON, the CCM sends messages to the IPMA over a private CAN. The IPMA then sends these messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the CCM, refer to the Network Message Chart in Description and Operation of the Anti-Lock Brake System (ABS) and Stability Control article.

DTC	Description	Fault Trigger Conditions
U2107:00	Collision Mitigation By Braking: No Sub Type Information	This DTC sets when the collision deceleration message from the CCM is sent too often or the duration of the message is too long. This is most likely caused by a network communication concern or an internal failure of the CCM.
