### Circuit/System Description

The electronic brake module (EBCM) receives a GMLAN message from the instrument panel cluster (IPC) indicating the the level of vehicle that the EBCM is installed to. This DTC will set if there is a mismatch between the information originally programmed to the EBCM (at the time of original installation) and the RPO data supplied by the IPC.

### 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

One or more of the following actions may occur:

• | The EBCM disables the Antilock Brake System (ABS)/Traction Control System (TCS)/Electronic Stability Control (ESP)/Electronic Brake Distribution (EBD) for the duration of the ignition cycle.

• | The multi function display (MFD) displays the ABS Fault message.

• | The multi function display (MFD) displays the Traction Ctrl Off message.

• | The multi function display (MFD) displays the Stability Ctrl Off message.

### Conditions for Clearing the DTC
