Understanding the CHECK DRL SYSTEM Warning

Modern vehicles come equipped with various warning indicators to alert drivers to potential issues. Unlike older models that relied solely on a CHECK ENGINE LIGHT, today’s cars feature multiple signals for different systems.

For Honda drivers, seeing the CHECK DRL SYSTEM warning is a call to action. This alert points to a malfunction in the Daytime Running Lamp system, which requires attention.

This warning is broad and doesn’t pinpoint a single issue. You or a professional mechanic will need to diagnose the specific problem with the DRL system.

Below are the typical issues affecting the DRL system.

Burned-Out DRL Bulbs – Light bulbs have a limited lifespan and typically need replacement every year or so. A 4-pack of DRL bulbs costs around $18. Replacing them can be challenging for some.

If you’re up for replacing the bulbs yourself, it’s doable with the right tools. Consult your vehicle’s manual for guidance on removing and installing new bulbs. You’ll need a flashlight, a flathead screwdriver, a regular screwdriver, replacement bulbs, and a small container for screws to avoid misplacing them.

Alternatively, a mechanic can handle the replacement. Expect to pay up to $100 for parts and labor.

A faulty bulb might also indicate an issue with the fuse.

Faulty Wiring or Circuitry – Damage from a collision, moisture exposure, or engine overheating can affect the DRL system’s wiring. Rewiring is complex, so it’s advisable to hire a professional mechanic for this task.

Defective Fuse – Fuses regulate electrical flow to protect systems like the DRL. A malfunctioning fuse fails to limit electricity, which can overload the bulb or system, causing premature burnout.

Replacing a fuse is straightforward and can usually be done yourself. A box of fuses typically costs less than $20.

Choosing the Right Bulbs

Not all DRL bulbs are universal. Depending on your vehicle’s make—such as Honda, Toyota, or Nissan—you may need specific bulbs. Check your owner’s manual to identify compatible bulbs. Local auto parts stores with knowledgeable staff can also guide you.

What Are Daytime Running Lamps (DRLs)?

All modern vehicles are equipped with a DRL system, though designs vary. DRL stands for Daytime Running Lamp, a key component of a vehicle’s lighting system.

The primary function of DRLs is to make your vehicle more visible to other drivers, signaling its presence and movements. Introduced in the 1970s, DRLs were designed to enhance road safety, particularly in low-light conditions.

DRLs are separate from low or high beams. In some vehicles, turn signals may integrate with the DRL system.

When you start your vehicle, the DRL system automatically activates the front and rear lights. These lights are subtle during the day but critical at night, helping other drivers notice your vehicle.

In some vehicles, DRLs activate when shifting gears or releasing the parking brake.

How to Diagnose the Honda DRL System

If your Honda’s DRL system is malfunctioning and the cause isn’t clear, follow these steps to troubleshoot.

• Ensure your vehicle is in park if it’s off. Start the engine.
• Shift into drive. The Check DRL System warning should appear. Then, turn off the vehicle.
• Find your owner’s manual in the glove compartment. If you don’t have one, search online for the manual specific to your vehicle’s make, model, and year.
• Look for the Fuses section in the manual. It will guide you to the DRL system’s fuse location.
• Identify the DRL fuse in the fuse box using the manual’s instructions.
• Remove the fuse using a fuse puller or a non-metal tool to avoid electrical shock.
• Inspect the fuse for signs of damage or burnout. If damaged, replace it with a spare fuse from your vehicle or purchase one from an auto parts store.
• If the fuse is intact, reinsert it into the fuse box.
• Restart the vehicle and check the DRL lights. If any light fails to illuminate, the bulb is likely the issue.

Final Thoughts

The DRL system enhances vehicle visibility, making it easier for other drivers to see you, especially at night. Without functioning DRLs, nighttime driving becomes riskier. When replacing bulbs, ensure they’re compatible with your vehicle. A blown fuse can also cause bulb failure, so check both components.
