Driver’s Guide: How to Reset ABS Light on Peterbilt Trucks

Peterbilt trucks are specially designed heavy-duty trucks that are widely used in commercial industries and business applications. These trucks are equipped with advanced Anti-lock Braking System (ABS) that enables safe driving and better braking performance. ABS is a safety mechanism integrated with the truck’s braking system that helps prevent wheel lock-up during extreme braking conditions, especially on slippery roads.

Sometimes, the ABS light on a Peterbilt truck may come on, indicating a fault or malfunction in the ABS system. This can be caused by various factors, including low brake fluid level, faulty wheel sensors, or damaged ABS module. The ABS light on a Peterbilt truck is usually an amber color and appears on the instrument cluster. The light can be annoying and distract the driver, and it can also indicate an underlying brake issue that needs to be resolved.

Resetting the ABS light on a Peterbilt truck is a straightforward process that can be done by the driver or a qualified mechanic. This guide will discuss how to reset the ABS light on a Peterbilt truck and provide some frequently asked questions.

Before resetting the ABS light on a Peterbilt truck, it’s essential to confirm that there’s no real issue with the braking system. Check the brake fluid level, the brake pads, and the rotors for proper operation. If there’s an underlying issue, it should be fixed before resetting the ABS light. If your truck is still under warranty, it’s recommended that you contact a certified technician to diagnose and repair the issue.

Here’s a step-by-step guide on how to reset the ABS light on a Peterbilt truck.

Step 1: Turn off the ignition

The first step is to turn off the ignition and ensure that all electrical accessories are off.

Step 2: Press and hold the ABS diagnostic switch

Locate the ABS diagnostic switch on your Peterbilt truck. It’s usually located on the dashboard or under the steering wheel. Press and hold the switch for about 10 seconds until you hear a beep sound.

Step 3: Release the ABS diagnostic switch

After the beep sound, release the diagnostic switch. The ABS light will start flashing quickly.

Step 4: Count the flashes

Count the number of flashes between the long pauses of the ABS light. For instance, if the light flashes four times and pauses for a long time, then flashes four times again, that indicates a code four fault. Note down the codes as they will help the technician diagnose the problem if the light comes on again.

Step 5: Turn off the ignition again

After counting the flashes and recording the codes, turn off the ignition again.

Step 6: Start the truck

Start the truck and observe if the ABS light is still on. If the light stays off, then you’ve successfully reset the ABS system. However, if the light comes on again, it’s an indication of an underlying problem with the ABS system that needs to be repaired.

In some situations, resetting the ABS light may not work, and the driver may need to take the truck to a certified technician for proper diagnosis and repair.
