In the name of science and the greater good,
here's a diy:
1. open your hood
2. locate main disa
3. unplug main disa
4. turn on car, go around the block.... (is there a code?)
-yes... no worries, turn off car plug disa back in, disconnect negative on battery (wait 10 seconds)
-no... right on, turn off car plug disa back in...
your contribution will be greatly appreciated
