Connecting STAR Tester:

The self-test connector and tester hook-up is identical on all models. A two piece self-test connector on the vehicle, plugs into a matching two-piece service connector at the end of the STAR/Self-Test adapter cable assembly, Fig. 13. To connect the STAR tester proceed as follows:
1. Turn ignition switch to OFF position.
2. Connect the color-coded adapter cable leads on to the STAR tester.
3. Connect the adapter cables two service connectors to the matching self-test connectors on the vehicle, Fig. 14.
To check the STAR tester, turn the power switch, located on the right side of the tester to the ON position. The tester will run a display check and the numerals 88 will begin to flash, Fig. 15. A steady 00 will then appear to signify that the tester is ready to start the self-test and receive service codes.
