The parking brake warning light on your 2016 Honda HRV is designed to illuminate when the parking brake is engaged. However, if the light stays on even after you’ve disengaged the brake, or if it flickers intermittently, it indicates a potential issue that needs attention.
This article explores the common causes behind a 2016 Honda HRV parking brake warning light and provides practical solutions to help you address the problem effectively.
Understanding the Warning Signs
Before diving into the causes, it’s crucial to recognize the different ways the parking brake warning light might behave:
- Solid Light: This usually indicates the parking brake is engaged. Always double-check the brake lever to ensure it’s fully released.
- Flickering Light: A flickering light often suggests a low brake fluid level, a faulty parking brake switch, or an issue with the electrical system.
- Intermittent Light: This unpredictable behavior could point towards a loose connection, a failing sensor, or a wiring problem.

Common Causes and Troubleshooting Tips
Here are some of the most prevalent reasons why your 2016 Honda HRV’s parking brake warning light might be activated:
1. Low Brake Fluid Level
The most common culprit behind a persistent parking brake warning light is a low brake fluid level. Brake fluid is essential for your HRV’s braking system to function correctly. As brake pads wear down, the fluid level naturally decreases. However, a leak in the brake lines can also lead to a rapid drop in fluid, triggering the warning light.
Solution:
- Check the brake fluid level. Locate the brake fluid reservoir under the hood, usually a translucent container with a “MIN” and “MAX” marking. If the fluid level is below the “MIN” mark, it needs to be topped up.
- Add the correct type of brake fluid. Consult your owner’s manual for the recommended brake fluid type for your 2016 HRV.
- Inspect for leaks. If the fluid level is consistently low, it’s crucial to inspect the brake lines, calipers, and wheel cylinders for any signs of leaks.
Expert Insight: “Regularly checking your brake fluid level is a simple yet crucial part of car maintenance,” says John Miller, a certified automotive technician with over 15 years of experience. “Ignoring a low brake fluid warning can lead to reduced braking performance and potentially dangerous situations.”
2. Faulty Parking Brake Switch
The parking brake switch is responsible for sending a signal to the car’s computer when the parking brake is engaged or disengaged. A malfunctioning switch can send incorrect signals, causing the warning light to illuminate even when the brake is not applied.
Solution:
A faulty parking brake switch usually requires replacement. While a skilled DIYer can attempt this, it’s generally recommended to have a qualified mechanic diagnose and replace the switch to ensure proper installation and functionality.
3. Worn-out Brake Pads
While less common, worn-out brake pads can sometimes trigger the parking brake warning light. The sensor within the brake pad system, designed to alert you about worn pads, might malfunction and trigger the parking brake light as well.
Solution:
- Inspect the brake pads. Check the thickness of your brake pads. If they appear thin or worn down, it’s time for a replacement.
- Check the brake pad sensor. If the brake pads are in good condition, the sensor itself might be faulty and require replacement.
4. Electrical Issues
Electrical issues within the parking brake system can also be the root cause of a malfunctioning warning light. A short circuit, loose wiring, or a blown fuse can disrupt the signal flow, leading to an illuminated warning light.
Solution:
- Check the fuses. Refer to your owner’s manual to locate the fuse box and identify the fuse related to the parking brake system. Replace any blown fuses.
- Inspect the wiring. Carefully examine the wiring harness connected to the parking brake switch and related components for any signs of damage, loose connections, or corrosion.

When to Seek Professional Help
While some causes of a 2016 Honda HRV parking brake warning light can be addressed with basic troubleshooting, it’s essential to seek professional help if:
- You’re uncomfortable working on your car’s braking system.
- You’ve tried the troubleshooting steps and the issue persists.
- You suspect a complex electrical issue.
Expert Insight: “The braking system is critical to your safety,” emphasizes John Miller. “If you’re unsure about any aspect of diagnosis or repair, always err on the side of caution and consult a qualified mechanic.”
Conclusion
A 2016 Honda HRV parking brake warning light, while seemingly minor, should never be ignored. Addressing the underlying cause promptly ensures the optimal performance of your HRV’s braking system and, most importantly, keeps you safe on the road. If you’re facing this issue, use the information in this article to troubleshoot the problem. However, always remember that professional help is recommended for a thorough diagnosis and repair, ensuring your peace of mind and safe driving experience.
