How to Prepare for the Self-Test
To check for codes without buying a code reader is simple. If your EEC is wired correctly, the engine light works, and there are not any electrical faults in the vehicle you can get the codes out of your EEC.
1. Turn key to OFF.
2. Get a length of wire that can connect the STI to the negative battery terminal or body ground.
3. Ground the Self-Test Input.
4. Get some paper and a pen.
5. Get comfortable in the drivers seat.
6. Try to keep your self from getting distracted from here on.
7. Turn key to RUN.
8. You will hear some relays engage and the fuel pumps prime the system. This is the EEC beginning the test.
9. When the fuel pumps stop be ready to count!

How To Count “Check Engine” Light Blinks
When the “Check Engine” light blinks during the test you will get several different blinks, the separation time between blinks is used to indicate what information is being displayed.
Turn key to RUN.
You will hear some relays engage and the fuel pumps prime the system. This is the EEC beginning the test.
The fuel pumps will stop and the EEC will now begin giving codes.
You may catch a brief flickering of the light. This is a rapid code read that is used by the code readers you can purchase. Do not worry all those rapid flashes you just say flicker buy will now be given at a slower pace of �, 2, & 4 second pauses.
First digit of first KOEO code (1/2 second between blinks)
2 second pause
Second digit of first KOEO code (1/2 second between blinks)
4 second pause
Next KOEO code
Once all KOEO codes are read the EEC will repeat them
6 second pause
Single Separator Blink (this indicates the change from KOEO codes to CM codes)
6 second pause
Codes from Continues Memory (uses same 1/2, 2, and 4 second timing as KOEO codes and also repeats them)
If nothing has been recorded by the EEC since last battery disconnect you will see:
Blink - 2 sec - blink - 4 sec - blink - 2 sec - blink - 6 sec - blink - 6 sec - blink - 2 sec - blink - 4 sec - blink - 2 sec � blink
This translates into 11-11 current condition (KOEO) and 11-11 in the continues memory (CM); or SYSTEMPASS
This may seem hard to count; recommendation is to record codes with slashes, and to lump them all together. Sort them out into numerical codes later. Here is an example of this:
This would give you codes; 41, 83, 14 & 18. If you miss some of the codes or feel you are counting wrong continue to count the remaining codes for practice and to compare to the next code test. When finished simply turn the key to OFF wait 15 seconds then back to RUN. The codes will be presented again.
Our OBD 1 system uses a 3 digit code system, here are all the codes and what they mean Ford Fuel Injection 3 Digit Self-test Codes 111-171 *all info above comes from that link*
This works and saves you from the cost of a scanner.
