Pinpoint Test BV: Abs (Anti-Lock Brake System) Module Communication Concern With SCCM (Steering Column Control Module): Notes
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Refer to MODULE COMMUNICATIONS NETWORK for schematic and connector information.
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 specified time frame, the ABS module sets Diagnostic Trouble Codes (DTCs). This can be due to a SCCM failure, a circuit failure on the CAN or an excessive load on the network. For information on the messages sent to the ABS module by the SCCM, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
