If you’re driving your Jeep Wrangler and notice the traction control light illuminating and staying on, it can be a cause for concern. Here’s what could be causing the issue and what you can do to fix it.
The traction control system relies on ABS sensors located at each wheel to detect wheel speed and prevent slippage. When one of these sensors malfunctions, the traction control light may stay on.
Overheating Brakes or Burnt Clutch
In certain Jeep Wrangler models, overheating brake pads or a burnt clutch can trigger the traction control light. The brake lock differential (BLD) can overheat the brakes when the traction control system malfunctions.
Electrical System Issues
A faulty Electrical System Saver (ESS) battery or charging system can cause various electrical issues, including the traction control light illuminating.
What to Do When Traction Control Light Stays On
Diagnose the Issue
To determine the specific cause of the traction control light staying on, it’s recommended to have your vehicle scanned for diagnostic trouble codes (DTCs) using an OBD II scanner. The DTC will provide information about which ABS sensor or other component is malfunctioning.
Replace the Faulty ABS Sensor
If the DTC indicates a faulty ABS sensor, it’s important to replace it promptly. This will resolve the traction control issue and restore proper vehicle stability.
Inspect Brake Pads and Rotors
If you suspect overheating brakes, inspect the brake pads and rotors for signs of wear or scorching. Use a laser thermometer to measure the temperature of each rotor during an incident. Replace any worn or damaged components as needed.
If replacing the ABS sensor doesn’t resolve the issue, consider checking for faulty wheel sensors. These sensors are responsible for detecting wheel speed and can also affect traction control functionality.
Address Electrical System Issues
If the DTC indicates an electrical system issue, inspect the ESS battery and charging system for any damage or malfunctions. Repair or replace any faulty components to restore proper electrical function.
If your Jeep Wrangler’s traction control light stays on while driving, it’s important to diagnose and address the underlying issue promptly. By following the steps outlined in this article, you can resolve the problem and ensure the safety and stability of your vehicle. Ignoring the traction control light can compromise vehicle stability, especially in slippery or hazardous driving conditions.
