Your vehicle’s anti-lock brake system (ABS) prevents the wheels from locking up in emergencies and restores traction to the tires. It’s an important safety feature that you shouldn’t overlook. The ABS module monitors the system’s various parts to ensure that it’s functioning properly. The question is, what options do you have if your vehicle’s ABS module is inoperative?
An ABS module, also known as an ABS control unit or ABS controller, serves as the ABS system’s central computer. It receives information from the wheel speed sensors, runs diagnostic tests on the hydraulic modulator valves, and controls those valves accordingly. Upon detecting a possible wheel lockup occurring, the ABS module controls the hydraulic valve assembly to prevent the wheels from locking up.
Some people refer to EBCMs as ABS control modules, but not all ABS control modules are EBCMs. EBCMs control the electronic braking system. In addition to the anti-lock braking system, EBCMs also operate the primary brakes and related systems such as traction control.
Replacing or repairing your vehicle’s ABS module is no small expense. It can be pricey, which is why it’s important to be sure your ABS module is damaged or inoperative before committing to replacing or repairing it.
The biggest indicator that something is amiss is an illuminated ABS light on your vehicle’s dash. Once you rule out issues with your vehicle’s brake system, try turning the ignition key off and on again to reboot the system. If the light goes away, there likely wasn’t anything wrong with the ABS module. If the light stays on, take your vehicle to a repair shop so they can use their scan tool to retrieve any codes and check the ABS datastream to determine why the code was set. ABS systems aren’t as complex as engine controls, but they still require an understanding of how the system works.
You can also try accessing the diagnostic trouble codes without an ABS code reader, but this process can be much more difficult. Some vehicles will cause their ABS light to blink on and off in a specific pattern that points to the correct trouble code. This will require you to pull one of the ABS module’s connectors and bridge two of its pins with a wire or a piece of metal. You’d then need to decode the blinks using a shop manual. It’s a complicated process overall.
It should be easier to identify what’s causing the trouble with your ABS system. Once you know the illuminated light isn’t caused by the system’s fuses, wires, or speed sensors, it’s time to look at replacing or repairing your vehicle’s ABS module, but be aware that the ABS module is almost never the problem, so double check everything else first.
Replacement ABS control modules are expensive because their inner hydraulics and electronics are difficult for the average DIYer to service. Some ABS modules are separated from the Hydraulic Control Unit, but many of them will come as a unit. Many people consider buying a used ABS control module instead. Secondhand ABS control module sellers pull the modules from older scrapyard vehicles and refurbish them for new users. But are these used parts worth what you’re paying?
The main benefit of used ABS modules is that they’re much cheaper than new modules. Also, if the module is from a reputable source, it provides similar output to a brand-new one. It also helps the environment by reducing the waste in junkyards and keeping materials out of the landfill. Using an OEM component, even if it’s secondhand, also helps increase your vehicle’s lifespan thanks to its custom fit.
There are also a few drawbacks to buying a secondhand ABS control module. You need to do ample research before buying a module. First, it must fit your vehicle, and finding the perfect fit can be difficult depending on how common your vehicle is. Reputable used ABS module sellers can check their stock for you if you give them your vehicle’s year, make, and model. Take care to avoid scammers.
Next, you’ll need to have the shop reset the ABS module’s VIN. A used ABS module does need to be programmed. Because it’s secondhand, a used ABS module carries the VIN of its original vehicle. You, the seller, or a reputable automotive shop will need to clear the VIN from the used ABS module before plugging it into your vehicle’s ABS system. Failing to do this will cause issues down the line.
If you take your vehicle’s ABS module to an auto repair shop, they might have a rebuilding service available. They’ll take your vehicle’s ABS module, repair it, and return it to you.
Like secondhand ABS modules, rebuilt ABS modules are much cheaper than brand new ones. Because it’s your vehicle’s original ABS module, you also don’t need to worry about resetting and encoding the module’s VIN.
Unfortunately, if the shop can’t fix your vehicle’s ABS module, this option isn’t available. If you had to ship the ABS module to the shop, those shipping fees would be non-refundable as well. In addition, you’ll probably have to pay for the shop’s diagnostic fee. If you end up buying a whole new ABS module in the end, paying the diagnostic fee can feel like a waste.
While used and rebuilt ABS modules are both good options, it’s also good to consider buying a brand new ABS module instead. While it’ll be much pricier than the other options, it’s also the safest and most thorough one. It’ll resolve all the ABS module issues, and you don’t need to worry about dealing with VINs. Choosing between a new, used, or rebuilt ABS module depends entirely on your budget and preferences. But at least now you know the benefits and drawbacks of each one.
You can find several used ABS modules for sale online, but you’ll have to consider your options carefully to make sure you’re getting your money’s worth. Here are helpful tips and tricks to keep in mind when browsing through used ABS modules for sale:
Check online how much a used ABS module for your vehicle’s year, make, and model typically costs. That way, you can avoid scammers trying to overcharge you.
Before you spend money on an ABS module replacement, make sure it’s what your vehicle actually needs. Carefully diagnose the source of the problem and rule out other possible causes, such as a faulty ABS pump or sensor.
Check the used ABS module for any cracks, dents, or other signs of damage. If you’re buying online, try asking for more photos or a video before sealing the deal.
If you’re meeting up with the seller in person, consider hiring a mechanic to go with you. A mechanic can check the condition of the used ABS module to make sure you’re getting your money’s worth.
It’s best to buy a used ABS module that comes with a standard warranty that protects you from faulty products.
The exact cost of a new ABS module can vary greatly depending on several factors, such as your vehicle’s year, make, and model. In general, however, you can expect to spend anywhere from $40 to $2,290 for an ABS module replacement.
In contrast, a used ABS module is usually much cheaper, with most selling for around $90 to $200.
Your vehicle’s anti-lock brake system is essential for keeping its wheels from locking up in dire situations, and the ABS module is an integral part of the system.
