REPAIRING A 2001 TO 2005 HONDA CIVIC DAYTIME RUNNING LIGHT MODULE

Symptoms are: The daytime lights do not work,the DRL light is on. The high beam or low beam only works on one side and replacing the bulb does not fix it.The other symptom that can happen is a buzzing noise from the passenger side dash that does not go away unless the regular headlamps are switched on with the light switch.
What you need to do to repair this issue is remove the daytime module and resolder the solder joints on the relays mounted to the printed circuit board.
The module is located on the left side of the lower dash.Remove the lower cover below the bottom of the steering column.
If you look up about 8 inches and to the left you will see a grey module approx about 4x3 inches and an inch thick with a white connector mounted to an angle bracket with a 10mm bolt. .remove the bolt and lower the module.
Squeeze in the tab to release the electrical connector .
Once the module is out,using 2 screwdrivers carefully pry open the module by prying where the 4 lock tabs are.Once the end cover plate is removed,slide out the pc board that the connector is attached to.
If you take a close look at that board you will see that the solder joints that connect the black relays are all broken.
Resolder those bad solder joints and slide the board back in and the end cover just snaps back in.Re install in order of removal.

I have a 2006 civic SI. DRL indicator is on, driver side low and high beam ok. Passenger side low beam ok but DRL and hi beam not working. Any help is appreciated.


When either the high or low beam light is out in either side, DRL (daytime running lights) indicator will come on. When one bulb goes out, that's a clue the opposite bulb will burn out soon, so its best to replace both bulbs. If it was a fuse issue, both left and right side would be out. If driver side is OK but passenger side is not, then its a bulb issue. A 2006 Honda civic takes 9006 (HB4) low beam bulbs and 9005 (HB3) high beam bulbs. Cheapest is online from Walmart site-2-store. After procuring, wear latex, vinyl, or ANY gloves to keep your (corrosive) oil skin from coming in contact with headlight glass bulbs. Your skin oil will chemically react and cause shorter life span on glass bulbs. Instruction don't tell you this, so you handle with your hands, then need to replace bulbs 3 years later instead of 5 years (or more) in the future. With gloves on, pop the hood and look behind each headlight. Turn counter clockwise to unlock headlight bulb holders. Its a quarter to half turn to unlock bulb holder lock. Replace one bulb at a time so you don't confuse high beam from low beam. The wire has a tab you need to lift to pull out & disconnect wire connector. You might need a slim narrow-**** (NOT phillips) screwdriver to lift the tab; or use your house key. Snap the wire connector to the new bulb, then twist into headlight housing to secure bulb holders, then move on to the next bulb to repeat the procedure. Pict below, 9005 high beam is on the left, 9006 low beam is on the right. Handle by grasping the plastic base, not the glass bulbs. The raised potrusion on the bottom center is where the tab locks onto wire connector. Replace all 4 bulbs now, but in the future, its likely the low beam will wear out before the high beam. In the future, replace only the pair, not all 4. The factory installs inferior bulbs that go out sooner, hoping you'll take to dealership and they ******** you with higher parts-n-labor fees. As opposed to Walmart online site-2-store, it would cost you AT LEAST triple in parts & labor from dealership to replace all 4 headlight bulbs :-(

daytime running light module location 2001 impala


The daytime running lamps in your 2001 Chevrolet Impala are controlled by the Body Control Module (BCM) Here is a description of how the system works:

The ambient light sensor is a light-sensitive transistor that varies its voltage signal to the Body Control Module (BCM) in response to changes in the outside (ambient) light level. When the BCM receives this signal, the BCM turns ON either the DRL or the headlamp relay for auto headlamp operation. Any function or condition that turns ON the headlamps will cancel the DRL operation.
Thirty seconds after you start the ignition with the headlamp switch set in the OFF position, the DRL will perform one of two actions:

Illuminate the high beam headlights at a reduced intensity in daylight conditions
Illuminate the low beam headlights in low light conditions
The DRL/EXT lamps fuse in the top of the engine fuse block supplies battery positive voltage to both the DRL switch contacts and to the DRL relay coil. When the BCM energizes the DRL relay coil, current flows through the right high beam lamp, to the left hand high beam lamp, to the energized DRL relay switch contacts, to ground G101.
The high beam headlamps are now in series, and split the voltage so that the headlamps illuminate at halt intensity. The DRL operates when the ignition switch is in the RUN position, and the parking brake is not set or the transmission is not in park. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate.

HIGH BEAM LIGHT STAYS ON IN DASH ...SWITCH GOES HIGH AND LOW BUT ONLY WORKS ON HIGH (ONE LIGHT) AND NO LIGHTS ON LOW


I have the same problem and I've tried two fixes so far and neither has worked.
- I replaced the daytime running light module and that didn't work
- I replaced the trun signal/hazard/light switch and that didn's work

I've had one comment that it could be a ground issue.
hope this saves you spending money on "fixes" that don't solve the problem

What is the DRL warning light on the dashboard of my 2007 Honda CRV?


On my 2007 Honda CR-V The DRL code appeared on the dash board. Additionally I had only one high beam (on the passenger side); both low beams were fine, but I did not have a Daytime Running Light on the drivers side. The DRL code was really misleading because the real problem was that the high beam element in the headlight bulb was burned out. Note that the daytime running light is not a seperate bulb -- it is the high beam element which is powered at a low voltage. Once I replaced the head light bulb everything worked fine and the DRL code on the dash board was gone. So if the DRL message appears what you really need to do is replace the headlight bulb (there are YouTube videos which show how to do this - but search for headlight replacement, not for DRL fix). Be careful not to touch the new bulb with you hands since premature burnout can occur from the grease off your skin. I got my bulb from Wal-Mart for $8.88 (it's a 9003/HB2 for the 2007 CR-V) -- that's a pretty cheap fix.
