Tip

ACURA LOW BEAM HEADLIGHT ISSUE


Acura's with daytime running light faults are draining their owners wallets. This feature, introduced in 1999, utilizes a low beam bulb containing an igniter/inverter circuit. The technology, although state of the art, has a serious flaw; Cost. Not just the cost of the bulb, but the tremendously inflated labor fee tacked on by dealers and repair shops.

There is a label on the back cover of the headlight assembly that warns of the presence of 24,000 volts which can kill you. This label is an attention getter. A safety statement; However it's a little over the top. The real message is clear; Take it to the dealer.

Others who experience loss of low beam lights, having not read the fright phrase, are shocked anyway when told; "This will cost you $600...it's the inverters". It's time to shine the high beams on the low beam issue.

The low beam bulb, roughly the same size as a regular bulb, has an electrode at it's base. Inside is a filament, igniter, and inverter circuit. This little bulb is what some mechanics refer to as "The Inverter". Some want to change the entire headlight assembly for $250 a side. In one reported instance, the customer was told they needed an entire front bumper and both headlight assemblies. Remarks like these boarder on the criminal. If you know it's only a bulb, why would you call it an inverter?

The price range of the low beam bulb is as wide as a canyon. Highs of $250 have been quoted. The bulb is manufactured by; Sylvania, Raytheon, and Heliolite, just to name a few. The best price I found is $61, although several were on E Bay for $45.

How do you change the bulb? I'll use a 2002 Acura TL as an example. The drivers side is the more difficult of the two.

Remove the positive battery cable...Remove the baffle that is in front of the air filter housing (2 plastic clips)...Pull the over flow container up and out...You will see a gray 2- wire connector under the light cover...Push down on the tab until it clicks...Pull back to release it...Now you can remove the cover over the bulb. It requires the use of a #20 Torx with a security tip. This tool is worth the $20 cost and can be purchased at major tool stores. You can find it quickly at; www.wihatools.com. Part #70142...When handling the new bulb it is EXTREMELY IMPORTANT to wear a pair of latex gloves...Skin oil transferred to the surface of the bulb will ruin it...Pull the old bulb and note the position of the electrode...Make sure the new one goes in straight; No twisting...Hold the bulb backing and install the locking clip.

If both bulbs work intermittently there is a wiring problem...Check for a solid ground (zero ohms on the X10 scale) on the black wire of the connector that was removed to replace the bulb; Measure with connector removed....Also, visually inspect the connector that plugs into the Daytime Running Lights Control Module located behind the left side of the dash; Pins have been known to back out of the connector housing.

The secret is out; It's only a bulb. Don't throw your hard earned cash into "The Money Pit".

2003 acura tl type s passenger headlight not working high or low


After studying the wiring diagrams for your vehicle, this is what I can tell you:

First, the possibilities for your problem depend a LOT on if your vehicle is equipped with daytime running lamps (DRL) or if it is equipped with standard head lamps.

Then, the passenger high beam circuit and low beam circuit are separate circuits as well as separate bulbs. One circuit has little or nothing to do with the other. About the only thing they have in common is the Passenger Multiplex Control Unit, or if equipped, the DRL Control Unit.

I do not see any single "wire" that could fail and take out both of these circuits at the same time. The power, as well as the ground circuits for these two bulbs come from entirely different places.

With all that said, I would say that you either have a failure at the passenger multiplex control unit or you have two separate problems. - PROPER DIAGNOSIS REQUIRED.

Acura 2003 3.2TL driver side headlight low beam is out...is not the bulb ..how can this be? any idea?


most newer vehicles have individual fuses and or relays that controls each headlight separately, check the fuse panel under the hood, inside the lid there is usually a listing of what the fuses and relays do. look for drivers side low beam and take a look at the fuse, if it blown, try to replace the fuse, but there is usually a reason why it blew in the first place.
How did you test to see if the bulb was still good? ive seen dead bulbs that still look ok, try and plug the bulb from the non working side into the working side and double check.

Trying to replace a front headlight bulb on 2001 acura 3.2 TL


Look for the end of the wire retainer clip. Unhook it and lift it up. Remember not to touch the bulb. But if you do, just clean it with a bit of alcohol.

btw - Here's a bit of info from a previous post of mine...
The low beams consist of three parts. The bulb, inverter/ballast and the ignitor. The bulbs usually start to loose their color long before they burn out. The inverters/ballasts either go out after a while or take a while to start up.

Before you spend money on a new bulb, try swapping it with the one on the other side. You'll need a security torx screwdriver to get the covers off of the back of the lights. Don't touch the glass bulbs. If you do, just clean them with a bit of alcohol.

If the problem stays on that side, try swapping the ignitors. They're mounted inside the black covers.

If the problem is still on that side you've got a bad inverter. They're mounted on the bottom of the headlight assembly. You'll need to remove the front bumper and remove the headlight assembly to get to it. (I recommend you take pictures as you remove things so can put them back together correctly.)
