Important: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
The electronic brake module (EBCM) receives a GMLAN message from each of the network modules. Each module contains its own unique identification (Id) code that must be learned into the EBCMs memory. Once all the IDs have been learned and vehicle speed is 25 mph, or greater, the EBCM continuously compares Ids in the GMLAN message to its learned Ids to determine if all the network modules are present.
The ignition is ON.
The EBCM has not undergone the programming procedure.
The driver information center (DIC) displays the SERVICE ABS warning message.
A current DTC will clear when the EBCM has undergone the setup procedure.
A newly replaced EBCM will set DTC C0569 on its initial ignition ON cycle.
