DRL Light on Honda: Meaning and How to Respond

Curious about the DRL light on your Honda? 

In this guide, I’ll explain the meaning of the DRL light and provide you with insights on how to respond when it illuminates.

What Does the DRL Light Mean on Honda?

DRL stands for Daytime Running Lights, which are designed to improve visibility during daylight hours. In Honda vehicles, the DRL system uses high-beam headlights at a reduced intensity.

The system automatically activates when the ignition switch is ON (position II) and the parking brake is released.

If you see the DRL light illuminated on your dashboard or receive the “Check DRL System” message on the display, it indicates that there may be a problem with the DRL system.

The specific cause can vary but is usually related to a malfunction in one of the DRL components, such as a bulb, relay, or wiring.

Is It OK to Drive With the DRL Light?

Yes, it is generally safe to drive with the DRL light on; however, you should address the issue causing the DRL light to illuminate as soon as possible.

Driving with a malfunctioning DRL system may affect your visibility to other drivers during the day, potentially compromising safety.

While the DRL light is not an emergency, it’s advisable to have the issue diagnosed and repaired promptly to ensure the proper function of your DRLs.

What Causes the DRL Light to Come on?

Burned-out Bulb (Most Common Cause)

The bulbs can burn out over time and need replacement. The DRL indicator may come on to alert you to this issue.

Electrical Problems

Electrical issues within the DRL circuit, such as blown fuses, malfunctioning relays, faulty connectors, or damaged wiring, can disrupt the proper functioning of the DRL system. Such problems may cause the DRL indicator to activate.

Faulty Multiplex Integrated Control Unit (MICU)

The MICU modulates the high beam headlight control circuit on and off (duty cycle), providing reduced voltage (approximately 6-8 volts) to the high beam headlights. This results in the high-beam headlights operating with reduced brightness.

A problem with this module can lead to the DRL indicator coming on, though this cause is less common. 

How to Turn off the DRL Light on Honda

Step 1: Check the condition of the bulbs

If you find a burned-out bulb, replace it with the appropriate type:

• Turn off the engine.
• Open the hood and locate the headlight assembly.
• Remove the connector.
• Grab the old bulb and replace the new one.
• Reconnect the connector.
• Test the new bulb.

Step 2: Inspect the DRL electrical problems

If replacing the DRL bulb does not resolve the problem, proceed to inspect the DRL electrical system including fuses, relays, connectors, or wiring.

Refer to your user manual to locate these components. Typically, you’ll find the DRL fuse and relay in the fuse and relay box under the dashboard. You can use the user manual or check the labels on the fuse box cover to identify the correct fuse and relay for the DRL system.

Carefully examine the DRL circuit for any signs of damage, loose connections, or corrosion, and repair as necessary. Pay close attention to the wiring harness and connectors associated with the DRL system.

For more complex electrical issues like the MICU, I recommend having a professional mechanic or visiting a Honda dealership to diagnose and repair any problems with the DRL system.

By following these steps, you can troubleshoot and potentially turn off the DRL light on your Honda.
