Pinpoint Test CI: Abs Module Communication Concern With GWM
Normal Operation and Fault Conditions
With the ignition ON, the GWM sends 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 GWM 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 GWM, refer to Network Message Chart , Description and Operation in the Service Articles.

| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U0146:00 | Lost Communication With Serial Data Gateway 'A': No Sub Type Information | This DTC sets when the ABS module does not receive any messages from the GWM within the allowed time. |
