How to Replace an ABS Control Module
Replace an ABS module can be a difficult task; there are high pressures in the brake lines that must be respected if you find yourself having to remove them; and the ABS module may or may not be replaced with the solenoid block.
Part 1 of 6: Locate the ABS module
The ABS module is bolted to a solenoid block that is connected to numerous metal brake lines. To locate the ABS module, you may need to lift the vehicle and remove some plastic covers, panels, or other components. The ABS module can be removed as a whole or just the electrical module.
Part 3 of 6: Remove the module and solenoid block as a unit
If your vehicle has high pressure within the ABS unit, read the specific repair manual for your vehicle. Mark the lines before removing them to ensure that you can reconnect them in their original positions. This configuration will vary greatly depending on the make and model of car.
Part 5 of 6: Install the new ABS module
The instructions below are specific to your vehicle’s manufacturer and don’t always need to be pre-programmed, but they can help you troubleshoot any problems with the module’s operation.
Part 6 of 6: Install the ABS unit onto the car
When tightening the brake lines, make sure the flare end is firmly seated; this can be an issue if one of the lines leaks and needs to be removed. Most vehicles can bleed the brake lines at the wheels; however, some vehicles will have elaborate bleeding procedures that must be followed.
Does ABS module need to be programmed?
Once everything is in place, the ABS module will need to be programmed, which will vary greatly depending on the manufacturer.
How do I recode my ABS module?
Click the “03-ABS Brakes” button on the Select Control Module screen. Click the “Coding – 07” button on the Open Controller screen for the ABS Brakes. On the Recode Module screen, paste the coding value from your clipboard as the new code and then click “Do It!”

How do I know if my ABS control module is bad?
Signs That Your ABS Module Is Faulty
- The ABS Warning Light Glows. The ABS system is specifically designed to prevent any wheel from locking up during heavy braking.
- An Unresponsive Brake Pedal.
- Increased Pedal Effort.
- Speedometer Failure.
How do I fix my ABS control module?
If your ABS Warning Light comes on frequently, your mechanic can try to reset the ABS control module (much like a computer) to see if it fixes the problem by disconnecting the positive cable from the vehicle battery and holding the brake pedal down to drain the vehicle’s electrical system.
Can you bypass a ABS sensor?
No dice; tried removing and replacing the resistor; same result; light remains on. At this point, the resistor fools the car into believing that a sensor exists, but it does not provide the necessary output.
Can ABS module be repaired?
ABS issues such as sudden ABS power loss, faulty wheel sensor codes, missing signals from the wheel speed sensor, and more can be fixed by an appropriate repair authority; however, because these issues can have different types of repairs, it is important to seek out a car mechanic authority for a fix.
What is ECU code?
The following information provides an overview of what’s typically involved in reprogramming a car. ECU programming is the process of taking a ROM file and permanently storing it inside a vehicle’s engine management ECU.
What is an ABS module?
The ABS control module is a microprocessor that performs diagnostic checks on a vehicle’s antilock braking system and analyzes data from wheel-speed sensors and the hydraulic brake system to determine when to release braking pressure at a wheel that is about to lock up and skid.
Will disconnecting battery reset ABS light?
Step One: Disconnect the positive cable from your car battery, then press and hold the brake pedal to drain the vehicle’s electrical system, which will result in a reset of the car’s central computer, which should reset the light if there are no other issues with the system.
What causes ABS to fail?
