You can still perform the KOEO AND THE KOER Tests.
Getting the obd1 codes need a couple of tools: a 4 inch long gage 16 jumper wire and a 12 volt test light. Both tools are hooked up to the diagnostic connector and when the ignition key is turned on (without starting engine) the codes will begin to flash in the test light, not in the dash panel. If there is no code, you will normally get code 11 or 111. On Fords, there are 2 test modes, the KOEO (key on engine off) and the KOER (key on engine running). Both test modes should be used to get the accurate evaluation of the stored fault codes.
