How to Replace an ABS Controller in a Toyota Tacoma

The Toyota Tacoma has an anti-lock braking system (ABS) controller that reduces the braking force to any wheel that is rotating significantly more slowly than the others. This prevents the brakes from locking during an emergency stop. You may need to replace the ABS controller if the ABS warning light comes on, although this does not necessarily make your vehicle unsafe to drive.

Instructions

1

Determine which ABS controller your Toyota Tacoma will need. You'll want to be sure the new controller is compatible with your make and model of Tacoma. ABS is offered on all versions of the Toyota Tacoma.

2

Detach the wiring harness connector for the ABS controller by pulling the release bar.

3

Loosen the fittings for the brake lines from the ABS controller with a suitable brake line tool such as a flare nut wrench. Disconnect the brake lines and plug the open ends to prevent brake fluid from leaking out.

4

Remove the bolts and nuts that mount the ABS controller bracket with a socket wrench and remove the ABS assembly from the vehicle. Unbolt the ABS controller from its bracket with a socket wrench.

5

Install the new ABS controller by reversing the removal procedure. Attach the ABS controller to the bracket and use a torque wrench to tighten the mounting nuts to 48 inch pounds and the bolts that mount the ABS controller bracket to 14 foot pounds. Use a torque wrench and brake line tool to tighten the fittings for the brake lines to 11 foot pounds.
