Converting from Halogen to OEM HID

[omar302]

Great that it worked. So now we know what it takes for an OEM Halogen to HID conversion. Direct swap plus As Built Data modifications using ForScan:

 

726-45-01 xxxx XXxx xxxx change value at XX to 7F

 

726-50-01 XXxx change XX value to 10

One more q. Does anyone have experience with 726-26-02, one place lists it as frequency and another lists it as change to linear power. Im trying to turn off the PWM to my OEM HID headlights and just use straight dc, I currently use a relay and capacitor and it works, or if I didnt, the HIDs would flicker. Thanks

Additional info, 726-02-02. Is xxxx-xxxX-xxxx, the capital X is 0 or 1.

Does anyone know which parameters to change so that DTCs wont come up and tell me my high beam and low beam headlights are out? Ive looked at several options but I dont see what appears to correspond. Thanks in advance.

Don't remeber reading any similar issue. Did you try this?

726-25-02 xxx* xxxx xxxx Headlamp Style Cfg: 0=BI_FUNC Halogen, 1=BI_FUNC HID, 2=Dual, 3=Quad

Yes, it is configured that way. 726-25-02 0001-xxxx-xxxx. I had to set this parameter to HID already. Because if you dont set it, flash to pass (high beams on OEM HIDs) wont work either. I found this out by accident when trying to use flash to pass while DRLs were on. So the car already is set and thinks its got HIDs...at least in one place, but I think there are other parameters where HID should be set also.

Found this in the F150 sheet:

726-27-01 0000 xxxx xxxx "Front Light Outage Detection Disable when adding aftermarket LEDs/HIDs in Halogen Bucket"

Though, on my Edge Sport with factory HID it is set as follows:

726-27-01 0100 0001 0057

Edit:

Also found this in the sheet:

726-26-02 xxxx xxxx x*xx Outage Headlamps Cfg: 0=none, 1=both, 2=high, 3=low

Mine is set as follows:

726-26-02 0001 0000 0056

I would try this one first since it seems to match, for my Edge at least.

Thanks omar302. I tried both and neither worked to prevent the dtcs from coming up.

I got the DTCs issue figured out, so that I no longer get DTCs on low and high beams. The parameters to set are 726-46-01 and 726-46-02. They are described as high beam open DTC and low beam open DTC. 0=unused, 1=used.

 

726-46-01 was 0001-0100-0076 on my car and I changed to 0000-0100-0075. 726-46-02 was 0100-0101-0078 on my car and I changed to 0000-0101-0077. This set the DTCs to unused.

 

How I figured it out was I printed the as built data from a new Edge on the dealers lot that had HID and then compared page by page to my Edge build data. I found the differing parameters and checked their definitions.

 

This is one more piece of the puzzle. ?
