11-1-11 My guess is your allright the way it is I would look at the guage cluster connector for corrosion I believe your park lights and dash lights are on the same circuit if the park lights work then it is likely a wiring or guage cluster ussue. code 18 in my book says a timing/tach issue and in the tech library says you touched the brake after it sent the cylinder code. Did you try turning the headlight knob it could be the dimmer for the dash lights also
can't be 11-1-11 and then more codes, unless there was additional tests run (koer, cylinder cut out...) i assume the 2x 11's are from koeo,(they always repeat) and the 18 and 74 were continuous, but without the op confirming this, it's nothing more than speculation, UNLESS those spesific numbers only have koer, or koeo or cont codes
