2006 Trailblazer Brake Controller Installation
The Chevrolet TrailBlazer is a sport utility vehicle that was a trim level of the Blazer from 1999 to 2001. General Motors made the Trailblazer a separate model in 2002 until the end of its production in the United States during 2008. All 2006 Trailblazers have an anti-lock braking system controlled by a microprocessor known as a brake controller, or Electronic Brake Control Module (EBCM). This device adjusts the braking force to each wheel during emergencies to prevent the wheels from locking.
Instructions
- 1
Remove the cable from the negative terminal of the battery with a socket wrench to prevent the discharge of electricity when you remove the EBCM. Clean the area around the EBCM in the engine compartment on the driver side of the engine. This will keep the braking components from becoming contaminated.
2Detach the connectors for the electrical wiring on the EBCM. Disconnect the four mounting screws on the EBCM with a T 25-Torx tool, and discard the screws. Pull the EBCM gently to remove it from the Brake Pressure Modulator Valve (BPMV).
3Clean the mounting surfaces on the BPMV with a clean shop towel to avoid contaminating the new EBCM. Fasten the new EBCM to the BPMV with a T-25 Torx tool, using new mounting screws. Tighten the mounting screws to 39 inch-pounds, working in an X-pattern. Attach the electrical connectors to the EBCM.
4Connect a scan tool to the vehicles data link connector which is under the instrument panel to the left of the steering wheel. Perform the tire size calibration function according to the scan tools instructions, and disconnect the scan tool. Connect the cable to the negative terminal on the battery using a socket wrench.
