Data Link Diagnostic Test
WARNING: This page is about a different car, the 2000 Ford Windstar and 1999 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
- Connect New Generation Star (NGS) tester to Data Link Connector (DLC), if not already connected. Select vehicle to be tested from NGS tester menu.
- Turn ignition switch to ON position. Rotate dial on NGS tester to menu item DIAGNOSTIC DATA LINK and press trigger. A test will be performed on the bus (circuits No. 914 and 915) for the module communications network and the ISO 9141 communication link (circuit No. 70). If NGS tester displays, SYSTEM PASSED, module communications network is operating properly. Return to article that directed you here and continue diagnosis. If NGS tester does not display SYSTEM PASSED, perform appropriate test. See DATA LINK DIAGNOSTICS NETWORK TEST table.
