Pinpoint Test BV: Abs Module Communication Concern With SCCM
Normal Operation and Fault Conditions
With the ignition ON, the SCCM sends messages to the GWM over the HS-CAN2. The GWM relays these 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 SCCM 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 SCCM, refer to Network Message Chart , Description and Operation in the Service Articles.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U0429:00 | Invalid Data Received From Steering Column Control Module: No Sub Type Information | This DTC sets when the selectable drive mode switch message from the SCCM indicates "switch state 2". |
