Pinpoint Test BP: Abs Module Communication Concern With GWM
WARNING: This page is about a different car, the 2022 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation and Fault Conditions
With the ignition ON, the GWM sends 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 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 the Network Message Chart .
DTC Fault Trigger Conditions
| 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. |
