Hookup and Vehicle Selection
Before any diagnostics can be performed on the communication system, use Rotunda New Generation Star Tester 007-00500 or equivalent to perform
the following steps:
1. Turn ignition switch OFF.
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. Connect the New Generation Star Tester to the data link connector (DLC).
5. If using an alternate power hook up, plug the power cable into the cigar lighter socket or into the battery hookup adapter.
6. Turn ignition switch to RUN. New Generation Star Tester will perform an initialization, which checks the New Generation Star Tester memory
and verifies the vehicle interface module matches the program card software. If the screen displays an error message, Appendix C in the Rotunda
New Generation Star Tester Operator Handbook, System Messages.

displayed on first row, then repeat steps 8 and 9. Otherwise, rotate dial to Selected Vehicle top row and press trigger.)
