Pinpoint Test Bx: Abs Module Communication Concern With The All-Wheel Drive (AWD) Control Module
WARNING: This page is about a different car, the 2023 Ford Bronco Sport. 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 AWD control module sends messages to the GWM over the HS-CAN1. The GWM relays the 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 AWD control module 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 AWD control module, refer to the Network Message Chart in NETWORK MESSAGE CHART .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U011D:00 | Lost Communication With All Wheel Drive Control Module: No Sub Type Information | This DTC sets when the ABS module does not receive any messages from the AWD control module within the allowed time. |
