How to Reset ABS Light on an International Truck

When your ABS light comes on, it’s easy to feel a mix of frustration and concern. This signal isn’t something you can ignore. Your truck’s braking system needs attention. However, resetting the ABS light on an international truck isn’t as complicated as it seems.

In this guide, you’ll learn how to troubleshoot and reset the ABS light yourself. You’ll understand the role of ABS clearly. Following simple steps will get your truck back in shape fast.

What Is Your ABS and How Does it Work?

Your ABS keeps your truck safe by maintaining control during hard braking and slippery conditions. You may wonder how this relates to repair costs; the factors that influence the cost of an ABS-related repair can vary widely. 

Corrosion on key parts like sensors can add to costs. Rust on the ABS module or ABS fuse also increases labor and part expenses. If the damage spreads to surrounding areas, such as the truck’s floor or roof, those repairs add even more to the bill.

Side panels or doors may need attention after collision. They can be affected by hits that cause damage. Repairing the ABS may reveal bigger problems. This is common if the trucker has been neglected for some time. Components like the ABS module and sensors are expensive. Labor costs rise when damage is more extensive.

Steps to Reset Your ABS Light

• Turn the Ignition Off

Before getting started, ensure the truck’s ignition is off. This prevents electrical damage and keeps the control system safe while working on the ABS.

• Disconnect the Battery

Head over to the battery and disconnect the negative terminal. Removing this connection helps reset the electrical system, giving the ECU/ECM and ABS module a fresh start. Be patient here; rushing could cause errors later.

• Wait and Reconnect the Battery

Wait for 15 minutes, and reconnect the negative terminal afterward, making sure it’s secured tightly. The power is back on, and the reset process is almost done.

• Start the Engine and Check the ABS Light

Turn the key in the ignition and start the engine. If the ABS light has turned off on the dashboard, the reset worked. If not, there might be more going on.

• Take a Test Drive

A test drive ensures the brakes feel right. Roll down the road slowly, press the brake pedal, and ensure the brakes aren’t locking up. Your ABS light should stay off and the system should work smoothly.

• Use a Scan Tool if the ABS Light Stays On

If the light stays on, the problem goes deeper than a simple reset. Grab a scan tool to check for fault codes in the ABS. These codes might point to faulty sensors, a bad ABS module, a dirty tone ring, or other issues. At this point, professional help might be the next best step. 

Common Causes of ABS Light Activation

Trailer ABS lights don’t come on randomly; they’re signals telling you something is wrong with your truck’s braking system. Here are the most common reasons:

• Faulty Sensors

ABS relies on sensors at each wheel to track speed. If one goes bad or gets dirty, it sends wrong signals to the ECU (electronic control unit), triggering the light. Sometimes, it’s just dirt or debris messing with the sensor’s connection.

• Low Brake Fluid Levels

Your brake system needs the right amount of fluid to maintain pressure. If the fluid runs low, the system can’t build up enough force, and your ABS light turns on. Check your brake fluid regularly; this issue is easily preventable.

• Worn Brake Pads

Worn-out pads don’t give enough friction for proper braking. If your pads get too thin, the ABS detects the imbalance and triggers the light. Not addressing this could lead to uneven braking.

• Electrical Issue

Sometimes, the wiring itself is the problem. Faulty wiring, broken connectors, or a dying ABS module might be behind your ABS light. This kind of issue is harder to spot, but more common than you think.

• Failed ABS Module

When the control module malfunctions, it struggles to manage the ABS. This could be the root cause of a consistently illuminated ABS light. If resetting the light doesn’t fix the problem, this is likely why. You may need to get an ABS code.

FAQs

Can you drive with the ABS light on?

You can, but it’s not recommended. The ABS light means your anti-lock braking system isn’t functioning properly. While you can still brake, your vehicle may skid during hard stops. It’s safer to get it checked immediately.

How do you check for ABS error codes?

You’ll need a diagnostic scan tool. Plug it into your truck’s OBD-II port, and it will read the fault codes from the ABS module. This can help pinpoint the exact issue causing the ABS light.

Can a bad wheel speed sensor cause other problems?

A faulty wheel speed sensor impacts traction control. It can also cause braking imbalances and stability control issues. It might also cause your vehicle to fail an inspection.

Does resetting the ABS light fix the problem?

Resetting the ABS light clears the error temporarily, but it doesn’t solve the root issue. If the problem persists, the light will come back on. You need to address the underlying cause, like a faulty sensor or low brake fluid.

How often should ABS light fix the problem?

There’s no fixed schedule for replacing ABS sensors. They should be checked during routine inspections or if the ABS light comes on. Replace them when they’re damaged or malfunctioning.

Can ABS issues affect my truck’s stability control?

ABS works with your truck’s stability control system. A malfunction in the ABS brake could affect traction. This increases the risk of sliding in wet or slippery conditions.

How much does it cost to repair the ABS?

The cost varies depending on the issue. Replacing an ABS sensor can cost $100 to $300. More complex repairs like replacing the ABS module can range from $500 to $1,200.
