dbw pedal help
so i've got a 2006 lm7 swap in my truck, harness and pcm have been flashed, motor runs smooth but i have NO pedal at all. I've got the #12590008 tac module and the 6 wire truck pedal and i get nothing. i can hear the throttle move when i first give it power but thats it.
where do i start? I've even tried an 2003-2005 tac/pedal and that didnt work either |

Re: dbw pedal help
Scan for codes (GOOD scanner or HPT). Do you see any codes (code U0107 for example is a clear indicator of dbw connection). A few things can cause it, code will help us aim.
The initial noise is the dbw check on the TB, its a sign the TB isn't mechanically broken, but it doesn't tell you much about the pedal, tac if applicable, or tune setup, etc).

Re: dbw pedal help
I'll get my odbII port hooked up tomorrow to see if i have any codes.
on my 12v source that powers the tac module. should it have power while cranking or just while the key is in the on position? |

Re: dbw pedal help
Do the pedal and tach module go together?

Re: dbw pedal help
from my research i've done.. yes. the motor is from a 06 silverado. so i matched the tac/pedal with my body 2006 silverado truck (module K and the 2pin plastic pedal)
I've also tried a module A tac and a pedal with the 10 pin on it. |

Re: dbw pedal help
Check for codes as Brew said this will give all of us the information needed to steer you the right direction. Who's harness are you using?

Re: dbw pedal help
Geek , This may be a long shot but I had the same thing happen . I could power the key and hear the throttle body test mode . It would crank and idle smooth but no throttle . I borrowed a throttle body and it worked great . So I took the electronics off another and put it on my existing throttle body and the same thing happened .
I took the electronics off and started looking . When I pushed on the blade I could feel a hint of a drag when fully closed but it would flip back with no problem . I took the blade out and cleaned up the alum housing where the shaft goes thru and also sanded on the blade slightly just to clean it up . I put it back together and felt much smoother . I was skeptical but I put back together and bolted it on and it worked . Apparently if the test mode feels any resistance it will lock the throttle body and keep it from working . |

Re: dbw pedal help
I had the same problem and it drove me crazy! I found the problem by finding the values online for the TAC module pins and checked the output with a voltage/ground tester you hook to the battery and found I was missing the ground on the rear of the right head. Tbrown
