Cycle the ignition from OFF to ON to OFF to ON to OFF to ON. Watch the
odometer. It will display one or mode diagnostic codes (Pxxxx, with xxxx
being a 4-digit number). When finished, it will display Pdone.
If you don't see at least Pdone, you didn't cycle the ignition properly. So
we're clear, you're not turning the key all the way to start. ON is the
position where all the dash lights come on. OFF is one position back from
ON. Complete the cycle within 3 seconds.
When you get the codes, post them here, and we'll take it from there.
turns out, just when this happened i got a notice from the dealer for an
old recall i never knew i had. go figure. it was for the blower motor
harness. they told me i had a leak. changed the gas cap and its been off
ever since. (fingers crossed). i copied on what to do for future
refrence if that light goes on again.
