Pinpoint Test S: Abs Module Communication Concern With TBM
WARNING: This page is about a different car, the 2023 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation and Fault Conditions
The TBM module may also be known as the TRM.
With the ignition ON, the TBM sends messages to the GWM over the HS-CAN3. The GWM relays these 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 TBM 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 TRMTBM, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U0137:00 | Lost Communication With Trailer Brake Control Module: No Sub Type Information | This DTC sets when the ABS module does not receive any messages from the TBMTRM within the allowed time. |
