Pinpoint Test R: Abs Module Communication Concern With CCM
Normal Operation and Fault Conditions
The CCM communicates with the IPMA over a private CAN. The IPMA sends the CCM messages to the ABS module over the HS-CAN2. If the ABS module does not receive these messages within the allotted time frame or if the messages contain invalid data, the module sets a DTC. This can be due to a CCM failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the CCM and IPMA, refer to the Network Message Chart .

| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U2107:00 | Collision Mitigation By Braking: No Sub Type Information | This DTC sets when the collision deceleration message from the is sent too often or the duration of the message is too long. |
