Yesterday, Thursday, November 3, 2005, is V-DRL Day :usa: for LX owners - the day the mystery as to why very few cars were able to have DRLs (Daytime Running Lights) enabled was finally solved.

Ever since DESIREE posted his success with having his DRLs enabled I've been trying to get mine to activate as well. Two visits to my very accomodating dealer, involving a total of 3 StarSCAN units and a couple dozen attempts were fruitless - DRLs showed enabled in starscan but would not function in real life.

Why would a few cars enable and others not was the mystery.

Last evening, as I was reviewing the list of changes to the latest CD update to starscan, version 6.03, the mystery was solved - the latest CD update to starscan, released 9/19/05 contained, among many other improvements, a fix to the DRL enablement option. Mystery solved: Those who had been successful had been enabled with an updated starscan unit, those of us for whom DRL enabling was a frustrating failure were using starscan units that were lacking the 6.03 update.

Today, at 7:15 AM Arizona time, with a starscan unit that proudly touted its 6.03 update in the upper RH corner, my tech & I successfully activated DRLs on my 300C. The process is simple: Enable, Disable, with accompanying tones & warnings lights, Enable. Done deal. Works good, lasts long time.

So head to your dealer with a dozen Krispy Kremes, a smile and "version 6.03 CD-only update" stenciled on your eyelid. You should come away a happy camper. :)

EDIT: DRL function details added:

With engine running, the DRLs will be illuminated anytime that the car's headlights are not on regardless of the position of the light switch, whether day or night. They cannot, in fact, be commanded off via the light switch, only replaced by head lamps.

Temporary disabling of DRLs:

Some owners have indicated a need to briefly disable DRLS, such as slow cruising through holiday light displays where the city requires parking lights only be illuminated.

A slight amount of parking brake pedal movement will extinguish the DRLs. On my car that occurs at about an inch of travel, to the first notch that will hold the parking brake pedal down. On my car there is no brake drag at that position, BTW, verified by rolling the car.

You'll know for sure your DRLs are off when the red "Brake" warning light, lower RH section of instrument panel, illuminates. It's instantaneous - as the Brake warning light illuminates, the DRLs extinguish, so no external "checking" to verify is required.

Caution: While no drag was apparent at the point in parking brake pedal travel where the Brake warning light came on and DRLs went off when I tested my 300C, one should only temporarily disable the DRLs via the parking brake when parked or in a low-speed parade, etc. Having the parking brake pedal depressed, even slightly, at speed could potentially result in significant friction-induced heat.

2d Edit: For those of you who may have missed it over on the FAW/Tech Forum, here's the checklist to print and present to your tech, hopefully with you at his side verifying the steps, one by one, if required:

Here, for easy reference by any Mopar service writer or technician with access to the StarSCAN tool, is the Technician's Checklist. Suggest you print a copy for presentation to your service writer.

Technician's Checklist - Daytime Running Light (DRL) enabling:

1. Verify your StarSCAN unit has been updated via update CD to version 6.03 or higher and displays "6.03" (or higher) in the upper RH corner of the display screen.

2. Enter Vehicle Preparation menu.

3. Select DRLs.

4. Select Enable (Note: some vehicles may already show Enabled, if so select Disable, then re-Enable.)

5. Select Disable. You will hear an alert chime and see various warning lights appear on the instrument panel.

6. Select Enable.

7. Start engine. Manually select headlamps to Off with light switch*.

8. Visually confirm DRLs on (High beam lamps partially illuminated). Note: DRL will extinguish with turn signal blinking, selected side. This is normal.


*Note for forum users: The instruction to manually de-select headlights (switch not in Auto or Headlight) is included to insure that the headlights won't be on during the attempt to visually verify that the DRLs are enabled. With the headlight switch in Auto and the car inside a service bay the headlights will frequently be on. Headlights always over-ride DRLs, and would thus keep the DRLs from showing - not good if one is attempting to visually verify that DRLs were, in fact, enabled. ;)

Reminder: With engine running, the DRLs will be illuminated anytime that the car's headlights are not on regardless of the position of the light switch, whether day or night. They cannot, in fact, be commanded off via the light switch, only replaced by head lamps.

You guys & gals are all in the wrong business, You should all be in Law Inforcement Cold Cases as you don't quit until you have an answer. Crime Rate would be ZERO. Thanks for your plugging away at this issue.

So are you saying that there are no parts involved, just software update? What did the dealer charge to do this? Can this be done if you have the HIDS?
It's possible that a minimum equipment list is required, jeepgrady. We need someone with a very basic 300 or 300C to attempt the enabling. If a no-frills car can be enabled, then all can.

So far the only cars I'm aware of that have successfully activated DRLs, all 300Cs, have these 3 items in common: NAV, HIDs, & backup warning.

No charge, other than I what I earlier suggested as the minimum equipment list to hit the dealer with. ;)

Thanks meister and DESIREE, you guys are a real asset to the forum. I am off to the dealer next week. The guys at my dealership are really nice, small town America. I am scheduled Monday morning. I did not ask about price since other s/w updates have been free. A box of KKs are a good tool, also a couple of Egg McMuffins for the SM and writer go a long way too.

Thanks to all

I went to the closest dealer to enable DRL's they wanted $40.00, can you believe that.
I then called my dealer(30 min. away), no charge, so I'll have to enjoy another drive in my 300C!
Thanks again for all the leg work you did. :banana:

No parts! No charge (except by the more ruthless dealerships, a.k.a "stealerships").
They just plug into the OBDII port with the StarSCAN tool (equipped with Rel. 6.03 software), and a few taps of the touchscreen, and it's done.
HIDS are not a problem because the DRL system uses the high beam lamps.
Talk to your service manager first about the status of the software in his StarSCAN tool, then ask HIM/HER to do it personally (he/she is not "on the clock" like a technician is), then GO GET'EM!

Good luck, jaydee - you'll be expanding the envelope.

Moral of the story: Never give up.

Can anyone attach some pics of what the car looks like with the DRLs on?
I have a picture, but don't know how to put it up on the forum. PM me with your e-mail address and I'll put it in a reply.
They look like 12-volt incandescent headlights with a bad ground connection. Half-bright, yellowish. When using the turnsignal the DRL on the side of the signal turns off to eliminate glare so that the turnsignal is more visible. A bit of overkill really. Use of technology for the sake of using it.

Oh geeeez

Does that mean I have to remove my Jet Chip first before going in to the dealer to ask him to do this?

This is a pain in the ass.

Desiree and Meister,
Thanks for all the investigating and troubleshooting regarding DRL's. I didn't enjoy having to use my regular headlights just to be more visible in the daytime. This forum is the BEST!

Hmmm

Were the DRL's an option or supposed to be standard equipment? I don't remember ever seeing them as an option item when I was in the market. :confused:

No worries, Chas. They're not looking for it and won't see it in the brief journey into the starscan to activate your DRLs. So leave it, and everything else, in place and enjoy the update.

I always roll in with everything I have, BTW, and no one notices.

I just called the dealership where I purchased my 300c and spoke with the service manager. At first, he thought I should be able to enable the DRL until I told him no one in the U.S. has been driving around with DRL on their 300's. He checked with his service techs and informed me that if the DRL's were enabled, it would change certain computer aspects of the vehicle such as going to the km (Candian) instead of the mph. (what we have always known here)

At this point, I told him about the latest StarScan version update that would allow the DRL to be enabled. He was not aware of this update but would speak to the manager above him who orders the latest tech. stuff. I laughed when he said that this would then allow the dealership to make a few more bucks by turning on all those 300 DRL. When I informed him he could simply do it without involving a service tech, he said that service managers are not allowed to touch OBD because they have not been trained/certified! He was a little perturbed that people on this forum knew things that only Chrysler-related people should know! So much for the freebie......(hope I didn't ruin this for others)
