### DTC Descriptor

DTC C0569: System Configuration Error

### 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 continuously compares Ids in the serial data message to its learned Ids to determine if all the network modules are present.

### Conditions for Running the DTC

Ignition ON.

### Conditions for Setting the DTC

The EBCM has not undergone the programming procedure.

### Action Taken When the DTC Sets

A DIC message and/or a warning indicator may be displayed.

### Conditions for Clearing the DTC
