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 FD-CAN. 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: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| 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. |
