Check engine light/codes
#2
#4
It can't be done through the climate head on the Brougham. You have to jump the last two terminals (toward the passenger side) on upper row of the ALDL. You can use a paper clip.
When you jump the terminals, turn the ignition to the run position, but DO NOT start the engine. The check engine light will begin to flash a two digit code. The first code will be 12 and will be presented as 1flash/pause/2flashes. Each code will flash 3 times.
Go to http://www.extreme-check-engine-ligh...%20Decoder.htm for a complete list of the codes.
