Pinpoint Test BQ: Abs Module Communication Concern With The IPMA
Normal Operation and Fault Conditions
The IPMA is an internal component of the Advanced Driver Assistance Systems (ADAS) module.
With the ignition ON, 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 IPMA 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 U023A:00 | Lost Communication With Image Processing Module A: No Sub Type Information | This DTC sets when the ABS module does not receive any messages from the IPMA within the allowed time. |
| ABS U053B:00 | Invalid Data Received From Image Processing Module A: No Sub Type Information | This DTC sets when the ABS module receives messages from the IPMA, but the messages contain invalid data. |
