What Does Check DRL System Mean on Acura?

Daytime running lights (DRL) has been mandated worldwide to increase motorists’ safety.

These lights indicate that the vehicle’s engine is on and increases the vehicle’s visibility in low-light conditions. Knowing the symptoms of a failing system, such as the daytime running lights, can save your life.

What the DRL Light Means

Please consult your vehicle’s owner’s manual for any manufacturer-specific details. If the DRL is on, the computer has probably recognized a problem. The DRL will turn on for several seconds after you start the car or until you disengage the parking brake, whichever comes first.

Once the system confirms that everything is functioning, this light will automatically switch off.

In most cases, a burned-out bulb will be to blame, but blown fuses and malfunctioning relays are also possible sources of electrical disturbances. Note that some setups will continue to flash this warning until the driver turns them off.

What Can Cause the Light to Come Up?

The daytime-running light feature can be implemented in a variety of ways; this includes the following:

  • It could be the steady-burning process of the front turn signals; or
  • The functional turning on of specific lamps; or
  • The operation of low-beam headlights or fog lamps at full or lower intensity; and
  • It could be dependent on the regulations in effect and the vehicle’s equipment; finally
  • The operation of high-beam headlights at a reduced intensity, and so on.

Functionally dedicated DRLs optimize possible improvements in safety performance, brightness, bike masking, and other downsides by separating the daytime running light from the headlamp’s other modes of operation.

How to Diagnose and Fix the Problem

  • The brightness detector is integrated into the dashboard. It is compatible with the vehicle’s automatic lighting system, so it can assess the ambient light and determine if the DRL lights or the headlights are required.
  • The DRL will activate in any gear so long as the transmission is in Drive, Neutral, or Reverse. It’s preferable to have a helper keep an eye on the headlights simultaneously. Chock the wheels to prevent the car from rolling away if you don’t have helpers.
  • If only one of your daytime running lights is out, the problem is either a burned-out bulb or a malfunctioning switch. Take the light bulb out of its socket to see if the filament has burned out and the bulb has to be replaced.
  • If only one of your daytime running lights is lit, you may need to check the fuse. If the fuse is blasted, the electrical circuit probably has another problem, such as faulty sockets or wiring. There’s also a chance the environment sensor is broken or unconnected.

Cost of Repair

A high-quality replacement daytime running light can be purchased for $20-$80. Brand preference and other factors can affect the final price.

The labor price will vary according to your car’s make and model and the rates in effect in your region.


Please remember to perform routine maintenance once you have changed your DRLs. When driving, it’s crucial to have all of your car’s lights working properly.

So, it’s not just the DRLs you should be keeping an eye on, but all of your car’s necessary lights. Have a good time looking for car lights, and drive safely!
