If you set your tires to 35 and do this the light should come on around 28 psi but these parameters can be viewed using techstream and going to the tire pressure ecu data list you can see your low tire pressure threshold for when it will set the light. Techstream is the replacement for diagnostic tester. You set your tires to where you want them, then press and hold the tire pressure button below the steering wheel for several seconds, the tpms light will flash 3 times then turn off - this is reset. If anyone could be of assistance, I'd really appreciate it. So, I've used TechStream to set up a new key, changed the interior lighting timer ,changed my rear wiper swipe time, and turned off the stupid driver side seatbelt chime.īut I don't know how to change the parameters for the low pressure warning light (I have tire pressure monitors, and can see the real time pressure and ID's for the sensors), and I'm not sure how to change the settings to have the sunroof or windows go down using the keyfob buttons.
