I posted this on Tech, but figured I'd try here as well.
I'm tuning on an 04 4x4 with 315/75/16's and a 3.73 rear. The stock setting on the tire was 29.something, I changed it to 35 to correct the speedo, but now it's throwing the Service Brake System message. I checked Nitto's site and they said the tire's actually 34.5, so I changed it to that hoping that's what it was, no luck.
Anyone else had this problem? What was it and what fixed it?
It's kinda wierd cause it will do it when you turn the key on, you turn the ignition back off and back on and everything's OK. Run the truck a little more, kill it, next startup, the Service Brake message is back.
