Pinpoint Test Ar: Abs Module Communication Concern With IPC
WARNING: This page is about a different car, the 2023 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation and Fault Conditions
With the ignition ON, the IPC sends messages to the ABS module over the HS-CAN3 through the GWM. 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 IPC 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 IPC, refer to the Network Message Chart in NETWORK MESSAGE CHART .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | This DTC sets when the ABS module does not receive any messages from the IPC within the allowed time. |
| ABS U0423:00 | Invalid Data Received from Instrument Panel Cluster Control Module: No Sub Type Information | This DTC sets when the ABS module receives messages from the IPC, but the messages contain invalid data. |
