Vent moves during tune

[clayt171]

Whenever I write a tune into the truck with the Diablo I hear a sound from the P/S under the dash that sounds like a vent is closing. This happen with all tuners? I always have the Climate Control turned off when loading.

Ya it would happen from time to time on mine. And then i would actually get a code from it. B0229

I think that when you flash the ECM it pulls all the power from the thing and thats why you here it close??? Not sure to be exact

Cool. It has never caused a code. Never had a failed load either. Was just curious as to what was causing it. Thanks

I have heard some trucks do it and some dont??? Ive flashed my truck well over a 1000 times and my heater still works

Mine does it everytime about 30 seconds into the flash. No codes no issues. Must be an LBZ thing. I can't explain Sweetdiesel's LLY issue though but like he said, nothing to worry about.

I get it too only once during each reflash at the end during reset:nana:
