The Chevrolet S-10 is a compact pickup that General Motors manufactured from 1982 to 2004. An anti-lock braking system, or ABS, has been a standard feature of of the S-10 since 1989. The ABS in an S-10 requires an electronic brake control module, or EBCM, to calculate the amount of braking force to apply during an emergency stop. The EBCM applies less braking force to a wheel that is moving more slowly than the others, improving the vehicle's braking ability when a wheel loses traction.
Things You'll Need
- Socket wrench set
- Clean cloth
- T-25 Torx tool
- Torque wrench
- Scan tool
Remove the cable on the battery's negative terminal with a socket wrench. This reduces the possibility of an electrical discharge damaging the EBCM when you replace it.
Wash the area around the EBCM with water and a clean shop cloth to prevent contamination of the EBCM. The EBCM is a flat rectangular box under the vehicle near the driver's side door. It sits atop the brake pressure modulator valve, or BPMV, which has the brake lines connected to it.
Detach the electrical connectors from the EBCM. Remove the T-25 Torx mounting screws from the EBCM with a T-25 Torx tool. Detach the EBCM from the BPMV by pulling the EBCM gently.
Clean the mounting surface of the BPMV with a clean cloth. Place the new EBCM on to the BPMV, and fasten new T-25 Torx screws to the EBCM. Tighten the screws to 39 inch-pounds with a T-25 Torx tool.
Attach the electrical connector to the EBCM. Connect the cable to the battery's negative terminal with a socket wrench.
Connect a scan tool to the data link connector in the instrument panel to the left of the steering wheel. Perform the tire size calibration function to program the new EBCM. A qualified mechanic typically performs this step.
