Normal Operations and Fault Conditions
With the ignition ON, the IPC sends messages to the TBM through the GWM over the HS-CAN3. If the TBM does not receive these messages within the specified time frame, the TBM sets a DTC. For information on the messages sent to the TBM by the IPC, REFER to: Auxiliary Brake System - Vehicles With: Trailer Brake Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U0155:00 | Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information | This DTC sets in continuous memory and on-demand if the TBM does not receive any network 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. |
