Understanding the Warning Lights
Decoding the Brake System Warning Light
The brake system warning light can indicate several issues, including low brake fluid, a problem with the anti-lock braking system (ABS), or a fault in the electronic parking brake. It’s crucial to address this promptly as it directly affects your safety.
Decoding the Check Engine Light
The check engine light, on the other hand, can signal a vast range of problems, from a loose gas cap to more serious issues like engine misfires or transmission problems. Its ambiguity can be frustrating, but a proper diagnosis is essential.

Common Causes of Both Lights Illuminating
Several underlying issues can trigger both the mazda brake system warning light check engine light. Here are some of the most common culprits:
- Low Brake Fluid: Low brake fluid can activate both warning lights, especially in some Mazda models. The system might interpret low brake fluid as a critical system failure, triggering the check engine light as well.
- Faulty ABS System: A malfunctioning ABS module can cause erratic behavior in the brake system, potentially triggering the brake warning light and prompting the check engine light due to communication errors.

- Vacuum Leak: A vacuum leak can affect braking performance, illuminating the brake warning light, and simultaneously impact engine performance, turning on the check engine light.
- Electrical Issues: Wiring problems or a faulty sensor can send incorrect signals to the car’s computer, triggering both warning lights.
“A thorough diagnostic scan is crucial when both lights are on,” advises John Smith, Senior Automotive Diagnostic Technician at Smith Automotive. “Guesswork can lead to unnecessary repairs and wasted time.”
Troubleshooting Steps
- Check Brake Fluid Level: Inspect your brake fluid reservoir. If it’s low, top it off with the correct fluid type specified in your owner’s manual. This is a simple check and could resolve the issue. For issues with the brake warning light on a Mazda Tribute, see: mazda tribute brake warning light on.
- Inspect Brake Lines and Hoses: Look for any leaks, cracks, or damage.
- Check for Vacuum Leaks: Listen for hissing sounds or inspect vacuum hoses for damage.
- Get a Diagnostic Scan: If the problem persists, use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs). These codes pinpoint the specific areas requiring attention.
“Never ignore these warning lights,” cautions Maria Garcia, Certified Master Technician at Garcia Auto Repair. “Addressing the issue promptly can prevent further damage and ensure your safety.”
