According to the 1994 F-Carline Service Manual, page 6E-6 states in part:

"Although it is recommended that a diagnostic scan tool be used to read diagnostic trouble code(s), it may be possible to flash trouble codes on certain vehicles equipped with a 12 pin DLC connector."

If your car does not have the 12 pin DLC connector, you may not be able to manually "flash" your trouble codes. The language "may be possible" appears to suggest that this method should work with most, if not all, 12 pin DLC equipped cars.

THE CONNECTOR
--------------------------
| 1 2 3 4 5 6 |
| 7 8 9 10 11 12 |
--------------------------

Pin 6 = Ground
5 = Diagnostic Terminal
2,12 = Serial data
1 = TCC (Torque Converter Clutch Solenoid)



DISPLAYING THE TROUBLE CODES



Some people with 94 models and on have had trouble using the following method, but it still won't hurt to try it. Ground Pin 5, the diagnostic terminal (into Pin 6), with the ignition off - then turn the ignition to the on position without starting the engine will flash the "Service Engine Soon" light in the following sequence. flash, pause, flash-flash, long pause flash, pause, flash-flash, long pause flash, pause, flash-flash, long pause Following this "12" code repeating three times will come

any trouble codes stored, flashing each of them three times. If you do not see the "12" flash three times, your diagnostic circuit could be defective. Otherwise you probably need a GM scan tool.

Some vehicles will display stored trouble codes, then "12" again, followed by energizing "most system controlled relays." The fuel pump relay will not energize. The idle air control valve will fully extend to enable checking minimum idle speed.

FIELD SERVICE MODE

Starting the engine with pin 5 grounded will place the system in "Field Service Mode" Open loop will result in the Service Engine Soon light flashing more than twice per second. Closed loop will result in (1) Light flashing once per second, (2) Light staying off when running lean, and (3) Light staying on if running rich.

CLEARING THE TROUBLE CODES

Turn the keyswitch to the off position. To clear any trouble codes, disconnect the power feed for 30 seconds. If this is done at the battery, and your car stereo is equipped and programmed with a four digit pin code, you may have to re-enter that as well to use your stereo again. A better place to remove power is at the fuse.
