OBD-I is pre 96 vintage truck coding use OBD-II for trucks of 96 & later years & requires a scan tool to read them. The Data Link connector is located below the steering wheel lower left rim of the dash just about knee cap height. Use a jumper (paperclip, etc) to connect these terminals. The connection/removal of the jumper between terminals (A&B) should be done with the ignition switch OFF. Also to prevent potential volt spike to PCM remove clip with Key OFF also.Once jumper is installed then turn key to on/run (not full start) to begin the flashing sequence The Service Engine Soon light will flash Code 12 three times to indicate that the diagnostics are working. Trouble codes will then follow, one at a time, three times each. DTC 12 will only appear if there are no other codes. 2 The codes appear in numerical order, and each code repeats itself three times before the next begins. This is different from some other ECM's. 3. It is helpful to the diagnostic process to know when codes are setting, particularly if there is more than one. Hence, clearing the codes is something you may wish to do. Clearing the codes may be accomplished by simultaneously depressing the brake and accelerator pedals fully while the PCM is in diagnostic mode (terminals A and B connected). It will not appear that you have cleared the codes until the next time you power up in diagnostic mode, however.
