WARNING: This page is about a different car, the 2010 GMC Terrain and 2010 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module (EBCM) must be configured with the security code, CAN configuration data and vehicle options. If not properly configured after installation, the EBCM may set a DTC.
The internal fault detection is handled inside the control module. No external circuits are involved.
