If you own a Jeep Liberty, you may have encountered the ESP BAS (Electronic Stability Program and Brake Assist System) light coming on while driving. This can be a cause for concern, as it indicates that there is a problem with the system that helps you maintain control of the vehicle. In this blog post, we’ll look at some possible causes of the ESP BAS light coming on and how to fix it.
- Check the ABS sensors
The ABS (anti-lock brake system) sensors on each wheel of your Jeep Liberty are responsible for detecting the speed of each wheel and sending this information to the ESP BAS system. If one of these sensors is malfunctioning or has a damaged wire, it can trigger the ESP BAS light. You can check the sensors by removing the wheel and inspecting the sensor and its wires for any signs of damage or corrosion. If you find any issues, you may need to replace the sensor.
- Check the brake fluid level
Low brake fluid level can also trigger the ESP BAS light, as it indicates a problem with the brake system. Check the brake fluid level in the reservoir under the hood of your Jeep Liberty. If the level is low, add some brake fluid until it reaches the “full” mark. If the brake fluid is consistently low, you may have a leak in the brake system that needs to be fixed.
- Check the brake light switch
The brake light switch on your Jeep Liberty is located on the brake pedal and is responsible for turning on the brake lights when you press the brake pedal. If this switch is malfunctioning or has a damaged wire, it can trigger the ESP BAS light. Check the switch by pressing the brake pedal and observing whether the brake lights turn on. If they don’t, the switch may need to be replaced.
- Check the wheel bearings
Worn or damaged wheel bearings can cause the ESP BAS light to come on, as they can affect the speed readings of the ABS sensors. You can check the wheel bearings by jacking up the Jeep Liberty and wiggling each wheel to check for any play. If you feel any looseness or hear any unusual noises, you may need to replace the wheel bearings.
- Check the battery voltage
Low battery voltage can cause various warning lights to come on, including the ESP BAS light. Check the voltage of your Jeep Liberty’s battery with a multimeter. If the voltage is low, you may need to charge or replace the battery.
In conclusion, the ESP BAS light on your Jeep Liberty can come on for various reasons, but the most common ones are related to the ABS sensors, brake fluid level, brake light switch, wheel bearings, and battery voltage. By checking these components and fixing any issues, you can restore the functionality of your ESP BAS system and ensure your safety while driving. If you’re unsure about how to perform any of these checks or repairs, consult a qualified mechanic.
How do I turn off the ESP BAS light in my Jeep
Once you’ve fixed the issue that caused the ESP BAS light to come on, the light should turn off on its own. However, if the light is still on after you’ve fixed the problem, you may need to reset it manually. Here are the steps to follow:
- Turn off the ignition and remove the key from the ignition switch.
- Wait for a few minutes to allow the system to reset.
- Reinsert the key into the ignition switch and turn it to the “on” position without starting the engine.
- Look at the dashboard and observe whether the ESP BAS light is still on.
- If the light is still on, turn off the ignition again and repeat steps 2 to 4.
- If the light is still on after several attempts, you may need to take your Jeep Liberty to a qualified mechanic to have the system diagnosed and reset.
It’s important to note that while resetting the ESP BAS light manually may turn off the light temporarily, it won’t fix the underlying issue that caused it to come on in the first place. So, if the light comes back on, you should check the system again and address any remaining problems.
