Selecting PCM Diagnostic Trouble Codes Display

Information Center Buttons:

NOTE: All PCM codes, whether current or not, will show as history codes.

To display PCM codes, enter diagnostic mode by grounding terminal 12 of the DLC connector, then select PCM as the appropriate module by pressing "TRIP RESET" until "4.0" is displayed in the trip monitor area of the instrument cluster.

Select "Display Codes" mode by pressing the "TRIP/ODO" button until "4.1" appears, then press the "ENG/MET" button to display the first code. Continue pressing the "ENG/MET" button to display any additional PCM codes. When all stored codes have been displayed, or if there are no codes, the indicator "---" will be displayed on the speedometer. If it is necessary to step backwards through the list, use the "FUEL INFO" button. The top of the code list will be indicated by the "---" display on the speedometer.
