Car Won’t Start Says Check Brake System
Possible Causes
- Low brake fluid
- Faulty brake light switch
- Problem with the brake system itself
How to Fix
Check the Brake Fluid
- Open the hood of your car.
- Locate the brake fluid reservoir.
- Check the fluid level. It should be between the “MIN” and “MAX” marks on the reservoir.
- If the fluid level is low, add more brake fluid. Use the type of brake fluid that is specified in your car’s owner’s manual.
Check the Brake Light Switch
- Locate the brake light switch. It is usually located on the brake pedal arm.
- Unplug the electrical connector from the brake light switch.
- Press the brake pedal. The brake lights should not come on.
- If the brake lights do come on, the brake light switch is faulty and needs to be replaced.
Check the Brake System
- If the brake fluid is full and the brake light switch is working properly, the problem is likely with the brake system itself.
- You will need to take your car to a mechanic to have the brake system inspected and repaired.
Additional Tips
- If your car won’t start and the “check brake system” message is displayed, do not attempt to drive your car.
- If you are able to safely stop your car, turn off the engine and put the car in park.
- Call a tow truck to take your car to a mechanic.
