Reading Codes, Self-Test Automatic Readout (STAR) Rotunda 007-00004, or STAR Rotunda 007-000717, or Equivalent
After hooking up the STAR tester and turning on its power switch, the tester will run a display check and the numerals 88 will flash in the display window, Fig. 15. A steady 00 will then appear to signify that the STAR tester is ready to start the Self-Test and receive the tests service codes. To receive the service codes, press the push button at the front of the STAR tester. The button will latch down, and a colon will appear in the display window in the front of the 00 numerals. The colon must be displayed to receive the service codes. If for any reason the technician wishes to clear the display window during the Self-Test, he must turn off the vehicle's engine, press the tester`s push button once to unlatch it (colon will disappear), then press the button again to latch down the button (colon will appear again). Every time the STAR tester is turned off, the low battery indicator (LO BAT) should show briefly at the upper left corner to the tester's display window. If the LO BAT indicator shows steadily at any other time during the operation of the STAR tester with any service code, turn its power switch to OFF and replace the 9-volt battery in the tester. The STAR tester will display the last service code received, even after it has been disconnected from the vehicle. It will hold the service code on the display until the power is turned off or the push button is unlatched and latched.
