Did I short out my SAFC

[wannaspoolRS]

one night the screen is lighting up just fine...go to bed, to school, then come home and the screen isnt turning on... The wiring was the same too. Checked everything to do with the power...nothing...b/c just for now until i learn more on tuning it to the RS i decided to just have it perform readings and not correct the fuel trims just yet. Confused about what sensor type it is also...but anyways anyone know what might have happened?????

This is normally an easy fix. Grab yourself a small screwdriver and take off the back of the SAFC-II. You will see where the wiring harness plugs into the unit. Normally from all of the vibration the harness will work itself loose. If that isn't the problem, take a look under the dash to make sure that the other end of the harness didn't come loose (I haven't seen this happen yet, but you never know ).

Let us know if that worked.
