Hi to everybody, I need help, I installed Quadzilla XZT module with Commamnder in my truck and when I started engine first time I get the check engine light and engine run very poorly. I find out that problem was bad connection on fuel pressure sensor, my fault I don't pushed OEM connector all the way to the Quadzilla harness. I fix it and engine run great,
but I can't get ride off the check engine light. When I scanned, on my scanner I get error message and if I try to erased anyway I get same error message on scanner screen. My scanner is a OBD II.
Any idea how to get check engine light ? Truck is a 2007 5.9 L CTD.
My scanner is probably 6 years old, not sure if any changes was done in new scanners. Please any idea will help, I don't like to go back to dealer doing that. I will need to take all out.

First the CEL should go off after 4 or 5 start and run sequences if actual problem is no longer present.

DC switched from OBDII to ScanBUS interfaces in 2006 I think, that is probablly why you older OBDII scanner won't work.

I don't think you have any thing to really worry about, codes from improper connections happen often. Maybe you can find a parts supply with a ScanBUS diagnostic tool to read and clear the code(s).

 

You local autozone should scan and clear codes for free.

 

Is this scan Bus interfaces you are talking about ?

Uh, yes CanBUS not ScanBUS, must be too early in the morning to have fingers and alcohol fogged brain working together.

DC ScanBus tool and CanBUS interfaces all ran together, need coffee
