Pinpoint Test Bx: Abs Module Communication Concern With AWD (All-Wheel Drive) Module
WARNING: This page is about a different car, the 2022 Lincoln Corsair. 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 module sends messages to the ABS module through the GWM over the HS-CAN 2. If the ABS module does not receive these messages within the specified time frame, the ABS module sets a DTC. This can be due to a AWD 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 module, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
