How to Install an EBCM in an Isuzu Impulse

The Isuzu Impulse was a three-door lift-back coupe that Isuzu made from 1981 to 1992. The models made from 1981 to 1990 had rear-wheel drive, while the 1991 to 1992 Isuzus had front-wheel drive. All versions of the Impulse used the same anti-lock braking system (ABS). The ABS requires a brake controller, also known as an electric brake control module (EBCM), to determine the amount of force the brakes apply during an emergency stop. The procedure for installing the EBCM is the same for all versions of the Isuzu Impulse.

Instructions

1

Remove the cable from the negative battery terminal with a socket wrench. This will avoid an electrical discharge during the EBCM removal procedure.

2

Disconnect the bolts that attach the passenger seat to the floor with a socket wrench. Move the passenger seat to gain access to the EBCM under the passenger seat.

3

Remove the attaching bolts for the EBCM with a socket wrench, and detach the electrical wiring harness from the EBCM. Disconnect the EBCM from the bottom of the passenger seat.

4

Install the new EBCM to the bottom of the passenger seat, and attach the wiring harness for the EBCM. Tighten the attaching bolts for the EBCM to 62 inch-pounds with a torque wrench.

5

Install the passenger seat, and fasten its attaching bolts with a socket wrench. Connect the cable for the negative battery terminal.
