ABS Light on After Tire Change: Reasons and Remedies
We will have a quick look at the reasons and remedies first.
| No. | Reasons | Remedies |
|---|---|---|
| 1. | Incorrect tire size | Change the tire |
| 2. | Wheel speed sensor malfunction | Replace the sensor |
| 3. | ABS module failure | Replace the ABS module |
| 4. | Incorrect Installation | Re-install the tire |
These are the key reasons for the ABS light on after a tire change in your car. Now, will have an in-depth discussion of each of the problems. So, let’s get started!
Reason 1: Incorrect tire size
Each vehicle is designed to work with a specific set of tires that meet certain specifications, such as size, load rating, speed rating, and other factors.
If the new tires that were installed on your vehicle do not meet these specifications, it can cause the ABS to detect a problem. The pro with the wheel speed, which can trigger the ABS light to come on.
Potential Fix:
To solve this issue, you need to make sure that the new tires are the correct size and type for your vehicle. Here are some points to be noted for the solution to this problem:
- Identify incorrect tire size: Check the size of the new tires against the old ones. The tire size is printed on the sidewall and includes numbers and letters representing the width, aspect ratio, and diameter of the tire.
- Check manufacturer’s specifications: Consult the owner’s manual or a qualified mechanic to ensure that the new tires are the correct size and type for your vehicle, including the width, aspect ratio, and diameter.
- Address the issue: Replace the new tires with the correct size and type for your vehicle, as specified in the owner’s manual or by a qualified mechanic.
- Check tire pressure and balance: Even small differences in tire size can affect the operation of the ABS. Make sure that the new tires are properly inflated and balanced to avoid triggering the ABS light again.
Reason 2: Wheel speed sensor
The ABS relies on sensors that detect wheel speed. The ABS light might illuminate if one or more of these sensors are broken or acting improperly. Roadside debris and weather exposure might harm the wheel speed sensors. They can also malfunction due to wiring problems or sensor calibration issues.
In addition to the ABS light coming on, you may notice other symptoms if the wheel speed sensors are damaged or malfunctioning. These can include uneven braking, a pulsing sensation when braking, or the traction control system not working correctly.
Potential Fix:
For this problem, the solution is to have the sensors checked and replaced if necessary.
A qualified mechanic can diagnose the issue by testing the wheel speed sensors with a multimeter or oscilloscope. They can also perform a visual inspection to check for any visible damage to the sensors or their wiring.
To place it, you can follow these steps:
- Step 1: Remove the wheel.
- Step 2: Check the sensor for any signs of physical damage.
- Step 3: Ensure that the sensor’s wiring is not harmed or unplugged.
- Step 4: Now, you have to reinstall or replace the sensor. If the damage is minor, you can reinstall it. Otherwise, you have to replace it.
- Step 5: After you fix the sensor, reinstall the wheel.
Reason 3: ABS module failure
The ABS module controls the braking force applied to each wheel based on input from sensors. If it malfunctions, the ABS light turns on as a result of a breakdown in communication and operation.
The ABS module can fail due to various reasons, including electrical issues, internal component failure, water damage, or general wear and tear over time. Electrical problems, such as corroded connectors or damaged wiring, can disrupt the communication between the ABS module and other components. And this can lead to module failure.
The ABS light will typically illuminate the instrument cluster when the ABS module fails. You may also experience other related symptoms, such as
- Loss of ABS functionality
- Increased braking distances
- Unusual brake pedal behavior
Potential Fix:
- Diagnostic process: Specialized diagnostic equipment is used to retrieve error codes from the ABS module, aiding in the diagnostic process.
- Addressing the issue: Solutions include repairing or replacing faulty electrical connections or damaged wiring. If the ABS module itself is faulty, it needs to be replaced and reprogrammed for proper functionality.
To replace the ABS module, you can follow these steps:
- Step 1: Gather all the necessary tools and disconnect the battery.
- Step 2: Locate the ABS module. It is located near the master cylinder or in the engine compartment.
- Step 3: By using a wrench or socket set, remove the old ABS module.
- Step 4: Install the new module as per the instruction.
- Step 5: Bleed the brake system to ensure that there are no air bubbles in the module.
Reason 4: Incorrect Installation
Incorrect tire installation can indeed lead to ABS malfunctions. When tires are not installed correctly, it can affect their alignment, balance, and overall performance. It, in turn, can trigger the ABS light to come on.
There are several potential causes for incorrect tire installation. These are including
- Inexperienced or untrained technicians,
- Negligence during the installation process,
- Using improper tools or techniques,
- Failure to follow the manufacturer’s guidelines for tire installation.
The ABS light coming on after a tire installation is a common symptom of incorrect installation. Additionally, you may experience unusual vibrations or noise while driving, uneven tire wear, or a pulling sensation to one side.
Potential Fix:
- Step 1: Diagnosing the issue: A visual inspection of the tires and wheels can help identify incorrect tire installation. A qualified technician will check for misalignment, improper seating of the tires on the rims, or any visible issues that could affect the ABS’s proper functioning.
- Step 2: Addressing the issue: The solution for incorrect tire installation is to have the tires properly reinstalled. This involves ensuring correct alignment, proper seating of the tires on the rims, and appropriate torquing of the wheel nuts or bolts.
Contact a mechanic is recommended to fix this problem. Only a mechanic can surely re-install the tire according to the right alignment and measurement.
