Normal Operation and Fault Conditions
With the ignition ON, the CCM sends 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.
PPT R ABS MODULE DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U0104:00 | Lost Communication With Cruise Control Module: No Sub Type Information | Sets when the ABS module detects any of the CCM messages are missing. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network. |
| U0405:41 | Invalid Data Received From Cruise Control Module: General Checksum Failure | This DTC sets if the collision mitigation by braking deceleration message checksum is invalid. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network. |
| U0405:82 | Invalid Data Received From Cruise Control Module: Alive/Sequence Counter Incorrect/Not Updated | This DTC sets if the collision mitigation by braking deceleration message count is out of range. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network. |
| U0405:86 | Invalid Data Received From Cruise Control Module: Signal Invalid | This DTC sets if the CCM is requesting an external apply of the electric parking brake and the vehicle is not in static mode. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network. |
| 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. |
