Pinpoint Test Ar: Abs Module Communication Concern With IPC
Normal Operation and Fault Conditions
With the ignition ON, the IPC sends messages to the GWM over the HS-CAN3. The GWM relays these messages to the ABS module over the HS-CAN2. 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 .
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. |
