fault codes?

[Tweaker_G]

I tried posting this question in the newbie forum, but nobody answered. In my 84 dodge daytona I was able to get fault codes by turning the key on-off-on-off-on and watching the check engine light to blink out codes. Would this work on a 94 laser? If not is there a similair method to get codes in a laser?

I know with the 2g non-turbo models you can turn the key on and off 4 times (i think) and the check engine light will blink out the fault code, not sure if it'll work on 1gs, but its worth a shot

Here is the procedure for retrieving diag codes on a 1G (taken from myzero.com which no longer works) After you get the code, tell me what it is and ill look it up (I have all the codes printed out and I dont know what website its from) BTW the method blackGSX described only works on 2G non-turbos, not 1Gs.

There will be a diagnostic code inside the ECU (Electronic Control Unit) if and only if the 'Check Engine' light on the lower left portion of the dash is illuminated. To get the code that the ECU is reporting follow these steps:

1. Locate the engine diagnostic test terminal located at the top of the drivers side kick panel (next to the fuse box).
2. You will want to count the pulses that are produced from the MPI terminal. The easiest way I found was to buy a 12v electric buzzer (Radio Shack #273-055 $2.49) and attach its leads to the terminal connector, then just listen for the pulses. You can also use an analog voltmeter and count the pulses displayed.
3. There are two types of pulses we are looking for "long" and "short". We are looking for a pattern where we have a series of long pulses (1 or more) and a series of short pulses (1 or more), then more long pulses. The codes always start with a long pulse and will finish with a short pulse. So start counting with the first long pulse after a short one. Count until you hear a long pulse after a short one again. NOTE: If you hear a constant "buzz", then your ECU is reporting that there is a problem with the ECU itself, if you hear only short pulses, there is no error code to report (i.e. normal state).
4. Lets say we write down: S-S-L-L-S-S-S-L-L. We know that we start and stop with a long pulse after a short one. So that happens at two places in our example. At the 2nd/3rd pulse set, and at the 7th/8th pulse set. The pulses between those two are what we want: L-L-S-S-S.
5. Now that you have the code, we need a code number. For every long pulse count it as a 10, and every short pulse counts as 1. So in our example, it is 10-10-1-1-1. Add them up and that is your code number, in our example 23.
