3. Use an OBD-II Scanner
The most reliable way to reset ESP and BAS lights is via an OBD-II scanner.
Steps include:

Pro tip: Always read the fault codes before clearing them to understand what caused the issue, especially if the lights come back soon after.
4. Manually Reset Using Drive Cycle (For Some Jeep Models)
In some cases, you can reset the warning lights via a drive cycle:
- Drive your vehicle at highway speeds (around 50 mph or more) for 10 minutes.
- Avoid sudden stops or braking intensely during this process.
- Once completed, turn off the engine for a few minutes.
- Restart your Jeep and check if the lights have cleared.
Note: This method doesn’t work for persistent faults but can help clear temporary glitches.
5. Inspect and Fix Underlying Issues
If warning lights persist, it’s essential to identify underlying faults:
