"Malfunction Indicator Lamp (MIL) Method
The Malfunction Indicator Lamp (MIL) on the dashboard may also be used to retrieve the stored codes. This method displays only the stored codes and does not allow any system investigation. It should only be used in field conditions where a quick check of stored codes is needed.
Follow the directions given previously for performing the scan tool procedure. To activate the tests, use a jumper wire to connect the signal return pin on the diagnostic connector to the Self-Test Input (STO) connector. The self-test input line is the separate wire and connector with or near the diagnostic connector.
Codes are transmitted by place value with a pause between the digits; Code 32 would be sent as 3 flashes, a pause and 2 flashes. A slightly longer pause divides codes from each other. Be ready to count and record codes; the only way to repeat a code is to recycle the system. This method may be used to read either 2 or 3 digit codes. The Continuous Memory codes are separated from the other codes by 6 seconds, a single flash and another 6 second delay."
Ok, so what holes do I connect the jumper wire into? So that I can read the flashing light for the code.
