Pinpoint Test R: Abs Module Communication Concern With CCM
Normal Operation and Fault Conditions
The CCM is an internal component of the Advanced Driver Assistance Systems (ADAS) module.
The Advanced Driver Assistance Systems (ADAS) module receives information from the forward looking radar module along a private CAN. The Advanced Driver Assistance Systems (ADAS) module sends 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 Advanced Driver Assistance Systems (ADAS) module 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 Advanced Driver Assistance Systems (ADAS) module, refer to Network Message Chart in the service information.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U0405:00 | Invalid Data Received From Cruise Control Module: No Sub Type Information | This DTC sets when the ABS module receives invalid data in the collision mitigation by braking brake system precharge message. |
| 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. |
