Esp Bas Light On

The ESP BAS light on the dashboard indicates that there is an issue related to the Electronic Stability Program (ESP). The ESP is designed to help keep the vehicle stable under different driving conditions by controlling brake pressure and engine output depending on road conditions and driver input. When this light comes on it usually indicates an issue related to brake pressure or wheel speed sensors.


When diagnosing this light you should first check all brake lines to make sure there are no leaks or breaks in them as this can cause the ESP BAS light to come on due to decreased brake pressure reaching the wheels. Additionally you should check all wheel speed sensors to make sure they are working properly as these can also cause this light to come on due to incorrect wheel speed readings being sent to the ECU (engine control unit).


If you find any issues such as leaks or faulty wheel speed sensors then these should be repaired before attempting any further troubleshooting. Once any repairs have been made then you will need to reset the ESP BAS light using a code reader or similar device that can access your vehicles onboard diagnostic system (OBDII). If all repairs have been made correctly then this should resolve any further issues related to this light coming on again.

Maintenance Tips

To ensure your vehicle runs optimally it is important that regular maintenance is carried out at least every 6 months or 10 000km (whichever comes first). This includes checking fluids such as oil, coolant and transmission fluid levels as well as inspecting lights and electrical connections for corrosion or other damage which could cause electrical faults in your vehicles systems which could lead to further issues down the line if left unchecked.

Parts Replacement

If any parts need replacing due to wear or damage then these should be replaced with genuine OEM parts from a reputable dealer as these are specifically designed for use in your vehicles engine components and electrical systems which will ensure optimal performance when used correctly. Additionally care must be taken when replacing any exterior lighting components (i.e headlights/taillights) so as not to damage them during installation as incorrect installation could lead to poor lighting performance when driving at night time which could pose a hazard on dark roads without adequate lighting visibility provided by working headlights/taillights etc..

Safety Warnings

When working with engine components or electrical systems in your vehicle it is important that you take all necessary safety precautions such as wearing protective clothing/gloves etc., using proper tools designed specifically for automotive use only (i.e ratchets/wrenches etc.) and having proper training before attempting any repairs yourself instead of leaving such work up to professionals who know what they are doing when dealing with such components which can be very dangerous if handled incorrectly . Additionally always make sure you have all necessary safety gear nearby whenever performing potentially hazardous tasks such as working underneath your car so you can safely get out from underneath it when needed without risking injury from falling debris etc..

Professional Assistance

When it comes to repairing a Chrysler 300’s ESP BAS light, it is important to get the right professional help. General mechanics may be able to diagnose and repair some issues, but for specialized work, you should look for a Chrysler-trained mechanic. These technicians are trained in the intricacies of Chrysler vehicles and can ensure that your car is repaired correctly. Additionally, they may have access to specialized tools and information that can help diagnose and repair the issue quickly and efficiently.

Tools List Required for Job Completion

When attempting to diagnose or repair a Chrysler 300’s ESP BAS light, it is essential that the technician have the right tools on hand. This includes voltage meter devices to test electrical components, as well as socket wrenches and sets to access various parts of the vehicle. Having these tools available will help ensure that repairs are completed quickly and correctly.

Work Environment Considerations

Finally, any technician working on a Chrysler 300 should consider the work environment when attempting repairs. It is important that protective gear like safety glasses and gloves are worn at all times while working on any part of the vehicle. Additionally, having adequate lighting in the area where repairs are being done will help improve visibility while making sure all tools are properly stored away before beginning work.
