Circuit/System Description

The electronic brake module (EBCM) receives a SERIAL DATA message from each of the network modules. Each module contains its own unique identification (ID) code that must be learned into the EBCM memory. Once all the IDs have been learned and vehicle speed is 25 mph, or greater, the EBCM will continuously compare IDs in the SERIAL DATA message to its learned IDs to determine if all the network modules are present.


Conditions for Running the DTC

The ignition is ON.


Conditions for Setting the DTC

The EBCM has not undergone the programming procedure.


Action Taken When the DTC Sets

The driver information center (DIC) displays the SERVICE ABS warning message.


Conditions for Clearing the DTC

A current DTC will clear when the EBCM has undergone the setup procedure.


Diagnostic Aids

A newly replaced EBCM will set DTC C0569 on its initial ignition ON cycle.
