Pinpoint Test Ar: Abs (Anti-Lock Brake System) Module Communication Concern With IPC (Instrument Panel Cluster): Notes
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Refer to VEHICLE DYNAMIC SYSTEMS for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
With the ignition ON, the IPC sends messages to the ABS module through the GWM over the HS-CAN3. If the ABS module does not receive these messages within a certain time frame, the module sets Diagnostic Trouble Codes (DTCs).
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 messages from the IPC. This can be due to a IPC failure, a circuit failure on the HS-CAN or an excessive load on the network. |
| ABS U0423:00 | Invalid Data Received from Instrument Panel Cluster Control Module: No Sub Type Information | This DTC sets when the ABS module receives invalid odometer information from the IPC. |
