Initial Inspection and Diagnostic Overview
New Generation Star Tester UsageNOTE: Rotunda Service Bay Diagnostic System (SBDS�), may also be used to diagnose this system. Refer to the SBDS operator's manual for diagnostic procedures.
NOTE: Ford DOES NOT provide procedures to retrieve Power Lock System DTCs or perform diagnostics without the New Generation STAR (NGS) tester.
New Generation Star Tester Hookup and Vehicle Selection
NOTE: Before any diagnostics can be performed on the communication system, the following special service tool must be used:
1. Turn ignition switch to OFF position.
2. Select the appropriate program card for the vehicle.
3. With the New Generation Star Tester control unit facing away from you, insert the program card into the slot on the back. If you insert the card incorrectly, New Generation Star Tester will not work.
4. Plug the New Generation Star Tester data link connector (DLC) cable to the vehicle DLC port (OBD-II Connector).
5. Turn ignition switch to RUN position.
6. Plug the power cable into the cigar lighter or into the battery hookup adapter if using the alternative hookup. New Generation Star Tester will perform an initialization, which checks the New Generation Star Tester memory and verifies the vehicle interface module (VIM) matches the program card software. If the screen displays an error message, refer to Appendix C New Generation Star Tester Operator Handbook, System Messages.
7. Menu item "Vehicle and Engine Selection" is highlighted. Press trigger to select.
8. Rotate dial to menu item "Select New Vehicle Model and Year - press trigger.
9. Select year: 1996, Vehicle: Windstar and appropriate engine by rotating dial to highlight selection, then press trigger to select. (If the selected vehicle is not displayed on first row, then repeat steps 8 and 9. Otherwise, rotate dial to Selected Vehicle top row and press trigger.)
Multiplex Communication Network Data Link Diagnostic Test
NOTE: The ignition switch must be in RUN position or test will fail. This test is used to verify the proper operation of communication Circuits of each module on the multiplex communication network or diagnostic communication network.
1. Perform New Generation Star Tester Hookup and Vehicle Selection as outlined.
2. Rotate dial to menu item "Diagnostic Data Link" and press trigger.
3. If results of Circuit 914 (+) = 0000 and Circuit 915 (-) 0000, then the Multiplex Communication Network link test passed. If non-zeros returned, then go to Communication System Diagnostics to continue diagnosis.
4. If results of Circuit 70 (LB/W) 0, then the Diagnostic Communication Network Link Test passed. If non-zeros returned, then go to Communication System Diagnostics to continue diagnostics.
