Fast flashing turn signal light

[RamDiver]

So got a brand new set from the company and still doing same thing.

Since I had the light assembly out,

I tried the factory headlight assembly and it to is doing the same thing.

But it's funny how when my drl ( got it programed to have the signal lights on) the turn indicators and side mirrors blinking normally. It's when the headlights turn on i get the hyper flash indicators and on the side mirrors but everything else flash normally.

I was reviewing this thread and a few questions have come to mind.

In the post I've quoted, are you saying that you re-installed the factory light housings and now they're misbehaving in the exact same manner as the aftermarket lights?

Are there any tweaks, modifications, changes or upgrades that you completed along with this housing swap and not yet mentioned?

Did you add DRL recently or during this light housing upgrade?


If your factory lights are now behaving the same as the aftermarket lights and were working before, I have to wonder what has changed besides any tweaks using AlfaOBD.

I tested fitted the factory light housings and they were acting the exact way as aftermarket lights.
Just led lights but had the same ones in the originals
I just added the drl with the aftermarket
Just changed the drl setting and the corner voltage to right side to 12 instead of 13

So, just so I understand.

Everything worked great with the OEM housings.
You updated the OEM housings with aftermarket housings and used AlfaOBD to add DRLs.

The only AlfaOBD tweaks were for the DRL, besides test enabling HID while searching for a solution.


Have you tested the functionality with all of the following AlfaOBD settings?

ECUConfig 3-DRL Customer Setting Option Present - Yes
CBC Features-DRL Configuration - Optional DRL
CBC Features-DRL Lamp Location - Turn Signal DRL
CBC Features-DRL Dropout Enabled - Yes
CBC Features-LED Dedicated DRL Present - Yes

And, if you manually added these changes, were any of them already set to the above configuration?

Yes everything worked great with the oem housing. When I switched to the aftermarket ones. That's when the issues started. When I tried to go back to oem still same issues. Yes. Didn't do 1st option but next 2 I did. But last 2 I didn't. When I did the 2nd and 3rd option you posted. Whenever the signal lights come on for the drl option. Everything blinks right. But soon as I turn on the headlights the issues start. None was already set.

I would try the dropout enabled - yes, that works on my truck but mine came with Halogen bulbs and required no tweaks with the LED bulb upgrade.

Keep in mind that the DRL sometimes require several ignition cycles before they function. Mine took a few days to work properly.

2013-2016 Ram trucks have often been more picky with LED lights.

Image a 2104 2500 Laramie, and my passenger headlight went out after both low beams had been dim for 2-3
Weeks. I replaced the both low and high beams with sylvania LED and both sides are extremely dim still. I’m getting 14v out of the housing plug and 11.5v coming out of each light plug in the housing. Any ideas? Incidentally my mirror turns signals are blinking fast too.

A band-aid solution for your dim incandescent lights by adding LED bulbs will likely complicate the fault diagnosis. I would recommend you take a short gamble before replacing the halogen lights to aid with troubleshooting.

Given the vintage of your truck, with your description, I'd start investigating the condition of common ground points near the headlights.

11.5 VDC is plenty for an LED bulb but I would guess that the measured 11.5 VDC is not with the LED light connected.

The ground location is likely rusted and/or corroded, that's often what happens. Trace the ground wires from the housings back to a common ground point. Yank the bolt out, sand the rusty area, coat it with conductive grease and retorque the bolt.

Then retest the headlights.


Also, it would be helpful to include the truck mileage and to add your relative location into your profile.
With living in the salt belt, there's a much greater chance of rust and corrosion versus living in Florida.

I already have the drl option working properly. I got it set for my turn signal to come on. That's the only time the signal indicators a side mirror turn signals work normally

I was suggesting you set the DRL dropout to fix your issue when the headlights are on because that's what works on my truck.

This setting turns off the DRL when the headlights are on which is when your problem appears.

AFAIK, that is the usual method when running DRL and you have an issue with your current configuration.

Our rolling computers don't always make logical sense with some of the necessary tweaks.

You can choose to spend ages tweaking endless options with AlfaOBD, if that is your preference.

You know what I'm going to try that in a few minutes.

 

[RamDiver]

You know what I'm going to try that in a few minutes.

Keep in mind, several of the AlfaOBD tweaks take numerous ignition cycles to become active.

I've tried cycling the start button without starting the truck and occasionally still had to wait a few days before the feature appeared.

So the drl dropout enabled is set to yes already.

Try adding

Have you been reading my posts???

I've repeatedly stated that several AlfaOBD changes require multiple ignition cycles and take several days to become available.
I've witnessed a few days and more before I've noticed any change.

I'm suggesting you replicate the settings proven to work with many other users but only changing one setting at a time is the best approach.

If you are unable to correct your issue after you've added each of the previously mentioned tweaks, I would strongly recommend re-installing the OEM lights, removing all the AlfaOBD adjustments and confirming the fault is resolved.

Then start adding ONE AlfaOBD tweak at a time, wait 72 hours (3 days) and observe the results.
This is a tried and true method of analysis and will likely lead to a successful outcome or at the least an understanding of the limitations of your truck's electronics.

Swap the old headlights back in and see if the issue goes away.

Quick question which pin in the factory projector harness is the turn signal pin?

Quick question which pin in the factory projector harness is the turn signal pin?

It appears to be pin 12 on both sides.

Thanks for your help, it’s a babied 2014 with 75000 miles, no real trailering except occasional side by side and no off-roading or mud. It has been exposed to some road salt here in West Virginia. How many ground points are there any idea about the locations. I would assume it’s pretty uniform for each vehicle.

You're most welcome.

And, thanks for updating your profile & location. This will often help when members are trying to assist you or if you're providing information or assistance to another member.

How many grounds? More than a few.

You could use the search icon in the upper-right corner or, your favourite search engine with something like 2014 Ram 2500 common grounds or ground faults followed by ramforum.com .

You might also download the service manual on a PC and use a word search (control F) with your favourite PDF viewer.

The 2012 service manual can be found below and should be sufficient.

Has anyone found a 4th generation service manual in a PDF format? If so can you please share the link? I can't get the McFall one to work on my phone. Thanks!

There should be 2 grounds for the lights one on each fender,the drivers side one should be fairly close to the fusebox,the pass side one should be just in front of the airbox.
