WARNING: This page is about a different car, the 1997 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
All Diagnostic Trouble Code (DTC) tests are for use with New Generation Star (NGS) scan tool. If a generic scan tool is used, ensure scan tool is certified OBD-II standard.
CAUTION:
Some Diagnostic Trouble Codes (DTCs) are related to more than one symptom test. To avoid replacing unnecessary components, do not retrieve Diagnostic Trouble Codes (DTCs) until instructed to do so. Start diagnosis by identifying symptom and then perform appropriate symptom test prior to retrieving any DTC's.
To verify module communication circuits and Generic Electronic Module (GEM) operation, perform DATA LINK DIAGNOSTIC TEST and ON-DEMAND SELF-TEST before retrieving DTC's. See MODULE COMMUNICATIONS NETWORK article.
- To retrieve Diagnostic Trouble Codes (DTCs), connect New Generation Star (NGS) scan tool to 16-pin Data Link Connector (DLC). DLC is located in center dash area. Turn ignition on.
- Rotate dial on scan tool to DIAGNOSTIC DATA LINK menu, and press trigger to select. Advance to next screen and select GENERIC ELECTRONIC MODULE. Advance to next screen and select DIAGNOSTIC TEST MODES. Advance to next screen and select RETRIEVE/CLEAR CONTINUOUS DTC. Advance to next screen and press start (3 button).
- At this screen, DTC's will be displayed. Record DTC's. To clear individual codes, rotate knob to highlight DTC then press 8 button. To clear all codes from selected module, press 7 button.
- If diagnostic system cannot communicate with GEM, see MODULE COMMUNICATIONS NETWORK article. After DTC's are retrieved, return to symptom test step that sent you to this procedure.
