I have gotten a tune on my 2004 G35 Coupe A/T, my anti-lag feature doesn't engage whilst im meeting all the requirements [above 30mph, above 3k rpm, engine up to temp] to do so, I have no dtc codes, and the ecm is reading the cruise control Cancel button is working when I press down, and my accelerator pedal meets the requirements for being fully depressed. Would there be any other reason this feature won't activate?

 

They didn't turn it on?

 

Ive contacted the tuner and they said they have turned it on, i forgot to add that my SET light blinks when I turn on cruise control and it won't engage, im not sure if those two things can be related. I've checked the stoppers for my brake and gas pedal and they're there and all of my steering wheel buttons work fine so I wouldn't presume the clockspring is bad.

 

Are you able to switch maps?

If your cruise control isn't working that could be an issue. I'd work with whoever did the tune to get it figured out

 

Yea i can change through my maps perfectly fine, I've checked with my scanner too that the ecm is reading and showing each button when I press them. My horn works too, all of my steering wheel functions work.

 

I wouldn't presume that. When the cruise failed on my 06 sedanX (RIP), everything else worked just fine and the issue was the clockspring. Not saying that's your issue, but I wouldn't discard it out of hand.

 

ahhh okok, is there anyway to diagnose if my clockspring is bad?
