Pinpoint Test Bx: Abs Module Communication Concern With AWD Module
Normal Operation and Fault Conditions
With the ignition ON, the AWD module sends messages to the GWM over the HS-CAN1. The GWM relays these message 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 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 the 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 module within the allowed time. |
| ABS U041E:00 | Invalid Data Received From All Wheel Drive Control Module: No Sub Type Information | This DTC sets when the ABS module receives messages but the messages contain invalid data. |
