NGS Hook Up and Vehicle Selection

NOTE: The Rotunda Service Bay Diagnostic System (SBDS), may also be used to diagnose this system.

Hookup and Vehicle Selection
Before any diagnostics can be performed on the communication system, use Rotunda New Generation Star Tester (NGS) or equivalent to perform the following steps:

1. Turn ignition switch OFF.
2. Select the appropriate program card for the vehicle.
3. With the NGS Tester control unit facing away from you. Insert the program card into the slot on the back. If you insert the card incorrectly, NGS Tester will not work.
4. Connect the NGS Tester to the Data Link Connector (DLC).
5. If using an alternative power hookup, plug the power cable into the vehicle's cigar lighter or into the battery hookup adapter.
6. Turn ignition switch to RUN. NGS Tester will perform an initialization, which checks that the New Generation Star Tester memory and verifies the vehicle interface module matches the program card software. If the screen displays an error message, refer to Appendix C in the Rotunda 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" and press trigger.
9. Select year, vehicle and 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.)
