The *definitive* BCM programming for adding OEM LED DRL/Turns to your Halogen JT as long as it has "Rubicon" flares ( Mojave etc )

Spent most of the weekend debugging this install. Seemed straightforward at first until I got into programming them in. Can't help with Sports, they need more stuff I believe such as the flares. Much or all of this info can be culled from various threads, but nothing definitive. Long winded post but maybe it will help someone some day. Dealer adding the DRL code will probably cause hyperflash unless your truck somehow has 2 extra wires mine does not have.

After install I set some options:

LED Dedicated DRL Present: Yes

LED Front Park/Marker Lamps Present: Yes

LED Front Turn Lamps Present: Yes

Signature Lamps or Mirror Repeater Present - Pin A5 & Pin A7: Signature Lamp

I looked at a compare file from a factory full LED Package equipped Rubicon and noticed some additional things.

There were some diagnostics settings the Rubicon had set "Yes" that mine were "No" for, so I flipped those to Yes:

Left Front Lamp Diagnostics Present - Pin F25: Yes

Right Front Lamp Diagnostics Present - Pin F28: Yes

Front Turn Lamps Diagnostics: Yes

All 3 of the above were "No" in my factory config. What's interesting is, the factory halogen front end has LED side markers. They were not bulbs on my factory Mojave I bought new. In, fact when I installed the OEM DRL/Turn assembly which came with new side markers and harness, the side markers were the exact same part #. So - even though "Front Park/Marker Lamps Present" was set to "No", they worked fine for over a year. You need to leave them NO, will get to that in a bit.

Then there are these settings the Rubicon had, but so did mine from the factory so no change needed:

DRL Customer Setting Option Present: Yes

DRL Configuration: Optional DRL

DRL Lamp Location: Dedicated

DRL Dropout Enabled: Yes

Right Dedicated DRL Lamp/Right Signature LED Present/Right Front Turn Signal #2/Headlamp Leveling Output Present: Yes

Left Dedicated DRL Lamps/ Left Front Turn Signal #2/Left Signature LED Present : Yes

Daytime running lights CSM Present: Yes

Connector A Pin 10 /Connector D Pin 5 : Side Repeaters/Front Side Markers Output Present: Yes


The first issue I had, was hyperflashing / turn signal out messages in the dash even though the turn signals were working fine. The turn signal in the OEM assembly is the lower bar, amber colored. The upper bar is the white DRL. The side markers turn on with the headlights.

REASON FOR HYPERFLASH:

I turned the Diagnostics settings to Yes, same as the factory LED Rubicon. Why doesn't it work? My halogen truck is missing the Diagnostics sense wire on both sides. While I do have the sense wire in the DRL assembly harness which plugs in the same vehicle side connector the halogen harness did, there is no wire from that connector to the BCM. Can you run it? Sure. Am I going to? No. So - LEAVE THESE turned off ( Set to "No" )

Left Front Lamp Diagnostics Present - Pin F25: No

Right Front Lamp Diagnostics Present - Pin F28: No

Front Turn Lamps Diagnostics: No

My halogen truck had the halo wire in the harness for the headlights, I guess I figured it'd have these wires too but it DOES NOT. If you get the factory code added to your build from a dealer, it will probably turn those 3 on ( unless they somehow figured this out and changed the code ) and you will hyperflash/have turn signal out errors in the dash.

Ok, no more hyperflash, everything working fine. No dash errors. I check codes though, have two:

What is this? The side markers work fine.

REASON FOR THE SIDEMARKER CODES:

I set the LED Front Park/Marker Lamps Present: Yes. Shouldn't it be Yes? They're LED right? As stated before, they are the SAME PART as the truck came with NO LED OPTIONS up front. That was set to No when stock. When you set to Yes, they also become part of the Diagnostic sensing circuit and the BCM thinks they're screwed up as it is getting no input due to the lack of the sensing wires. However, there is no option to turn that diagnostic off the way you can the front turn lamps diagnostics. I then set it to No, clear codes, and after 5 sleep cycles the codes have not returned. They don't flash or flicker, they aren't the same as the other LED lights which require the "LED" setting.

Everything is working fine now with no codes. If I did this again, this is all I needed to set:

LED Dedicated DRL Present: Yes

LED Front Turn Lamps Present: Yes

Signature Lamps or Mirror Repeater Present - Pin A5 & Pin A7: Signature Lamp

Nothing else.

If you went all in and added the Sense wires to the BCM, you'd set these additional 4 options:

LED Front Park/Marker Lamps Present: Yes

Left Front Lamp Diagnostics Present - Pin F25: Yes

Right Front Lamp Diagnostics Present - Pin F28: Yes

Front Turn Lamps Diagnostics: Yes

To clarify again, these settings are needed but were already set the same as an OEM LED truck for me:

DRL Customer Setting Option Present: Yes

DRL Configuration: Optional DRL

DRL Lamp Location: Dedicated

DRL Dropout Enabled: Yes

Right Dedicated DRL Lamp/Right Signature LED Present/Right Front Turn Signal #2/Headlamp Leveling Output Present: Yes

Left Dedicated DRL Lamps/ Left Front Turn Signal #2/Left Signature LED Present : Yes

Daytime running lights CSM Present: Yes

Connector A Pin 10 /Connector D Pin 5 : Side Repeaters/Front Side Markers Output Present: Yes




Good grief....

I wonder if it's because the LED corner lights are voltage regulated differently and so are handled differently than the other LED lights like tail or head lights?

Signature Light Present: Yes
Dual Filament Headlamp: No
Front Turn Lamps Diagnostics: Yes
Auto Headlamp On Threshold (0-5 V): 3.314 V
Auto Headlamp Off Threshold (0-5 V): 2.549 V
Left Side DRL Voltage Target: 11.0 V
Right Side DRL Voltage Target: 11.0 V
Left Low Beam Voltage Regulation: 13.4 V
Left High Beam Voltage Regulation: 13.4 V
Right Low Beam Voltage Regulation: 13.2 V
Right High Beam Voltage Regulation: 13.2 V
Left Front Corner Voltage: 13.4 V
Right Front Corner Voltage: 13.4 V
Left Rear Corner Voltage: 13.6 V
Right Rear Corner Voltage: 13.6 V

I'll update 1st post later, watch this if doing OEM LED DRLs on a factory halogen truck:

Thanks for the detailed explanation. Very helpful when I recently upgraded my Halogen DRL to the Mopar LEDs. I can confirm that depinning PIN 1 will resolve the marker code. For the fun of it it removed pin 1 on the passenger side and left it pinned on the driver side. Cleared the codes with JSCAN. After driving around for a while, the driver side code was thrown again. Now both sides are depinned and no codes thrown.

Thank you for making this comprehensive guide.

Been searching for information for some time and this is exactly what I have been looking for!
