Using a voltmeter
Each code is usually two digits, sometimes three. Look for 2 second pause between digits.
example swing swing Pause swing swing swing = 23
Open the hood and look for Self Test Ouput (STO) and Self Test Input (STI) connectors under driver's side hood, near cowl by the strut tower.
The STO connector is hexagon with six connections on it. Two connections on top and four on the bottom.
The STI is little square with one connection.
You must connect a piece of wire from the STI to the STO top row second connector of the STO
Attach the Volt meter possitive to the STO second connector on the bottom row. Run volt meter negative to the Vehicle Batterys positive
Turn on key.
The first set of codes tells you that your car is a V8. Then you will start to see a patern
Then starts the the swing swing two second pause swing swing swing. Or what ever code you are getting.
This these are KOEO codes.
To get KOER codes you must erase KAM, which you pull the negative battery cable off the cars battery for 10 minutes
I personally bough a 22 dollar code reader from Walmart that you just have to follow there directions. It is much easier.
