The Installation of a 1997 Chevrolet Brake Controller

Modern vehicles, such as a 1997 Chevrolet, may have an anti-lock braking system (ABS) that prevents the wheels from locking in an emergency stop. The brake controller is also known as an Electronic Brake Control Module (EBCM). It monitors the rotational speed of each wheel and decreases the braking force to a wheel that is rotating significantly slower than the other wheels. The procedure for installing an EBCM is generally the same for most Chevrolets made between 1997 and 2000.

Instructions

1

Locate the EBCM. Its under the dashboard to the left of the steering column.

2

Squeeze the pressure tabs on the bracket for the EBCM to release it from its bracket.

3

Detach the electrical wiring harness from the EBCM, and remove the EBCM from the vehicle.

4

Plug the electrical wiring harness into the new EBCM. The harness will make an audible click when the connection is secure.

5

Install the new EBCM to its mounting bracket and secure it in place with the pressure tabs on the bracket.

6

Connect a bi-directional scan tool to terminal 9 of the data link connector (DLC). The DLC is in the instrument panel to the left of the steering column. Read and correct any diagnostic trouble codes related to the braking system. Disconnect the bi-directional scan tool from the data link connector once youve read and addressed the codes.
