    2007 Tahoe 5.3l AFM DOD delete thread

    Well after messing with this for weeks and basically going over the entire install, buying HP Tuners to play with the tuning, we couldn't get it to quit throwing the service brakes message, so we swapped cams to a TxSpeed stage 2 and retuned. Absolutely no issues with the brakes with the...

    If possible it would help since we are running the same cam setup.

    This is close to the same we were seeing in the snap on unit, and through the gauge. Under power and above idle the brakes work as normal, but the pedal shudders and brakes are softish backing up. Been talking withe the shop and they are going to go through the tune, and I am purchasing the...

    So we got into it a bit Sunday, replaced bad intake gaskets. The vacuum gauge reads 9-10 at idle of 670 rpm which jumps from 575-670 rpm, the gauge reads 10-14 at 800 rpm and 12 on the MAP sensor VIA snap on unit, seems vacuum is really low

    This is exactly whats happening when it triggers the message, and its very random. Otherwise it runs great and functions normally.

    I have a crew 06 5.3 thats running a TSP chop monster and all supporting mods, so what it feels like isnt the cam. I am looking at anything other than the cam now, just really strange timing for this. But we are gonna get into it further this weekend and see. The shop that tuned the Tahoe...

    We found a very small intake gasket leak, (the shop reused the factory ones) but not sure if thats enough to cause this. Put a Snap on unit on it and ran through everything, no codes and all sensors mentioned tested fine. The last time it threw the light on, i was backing down the drive way...

    Yeah, wasnt sure if being new would get a thread going. The service brakes light only came on after the cam, no issues with the vehicle before. DOD was tuned out for years before the swap, the light is random but usually comes on after tapping the brakes and then putting pressure on it to stop...

    So I just had my 2011 tahoe swapped with BTR stage 2 cam and now get service brakes soon light. It doesn’t store the code and only comes on randomly, and clears with key cycle. Anyone ever run into this? Everything normal before, swapped vacuum sensor at brake booster and no change.
