How to Hook Up the Brake Controller on the 2006 Duramax

Duramax is the name of an 8-cylinder 6.6-liter diesel engine that General Motors has manufactured since 2001. The 2006 version carries the LLY designation and is an option for many full-size Chevrolet pickup trucks. The braking system on vehicles with a 2006 Duramax engine includes an electronic brake control module. The function of the EBCM is to keep the wheels from locking during an emergency stop by applying less braking force to a wheel that is rotating more slowly than the other wheels.

Instructions

    1

    Remove the negative battery cable with a socket wrench to prevent anyone from inadvertently starting the engine. Raise the vehicle with a floor jack and support it on jack stands. Clean the area around the EBCM under the vehicle with a shop cloth to prevent contamination of the disassembled braking components.

    2

    Disconnect the mounting screws for the EBCM with a socket wrench and discard the mounting screws. Pull the EBCM down slightly to detach it from the brake pressure modulator valve, or BPMV. Discard the EBCM.

    3

    Clean the mounting surfaces on the BPMV with a clean shop cloth to ensure a good electrical contact between the EBCM and BPMV. Install the new EBCM to the BPMV with new mounting screws and fasten the mounting screws with a socket wrench.

    4

    Lower the vehicle with the floor jack. Attach the negative battery cable with a socket wrench.

    5

    Turn the ignition on. Connect a scan tool to the data link connector under the dashboard on the left side of the steering column. Check and clear any error codes that the scan tool displays.
