TROUBLESHOOTING
DISPLAY PROBLEMS
If the display does not illuminate
•
Check connection to the battery.
•
Battery may be too low to power the analyzer (below 1 volt). Fully
charge the battery and retest.
•
Internal 9-volt battery may need to be replaced. Replace the 9-volt
battery and retest.
•
If the analyzer detects computer or ignition noise, a SYSTEM NOISE
message will appear on the display. Verify that all vehicle accessory
loads are off and the ignition switch is in the off position. The ana-
lyzer will automatically retest when the system noise is no longer
detected. If the SYSTEM NOISE message continues after several
retest attempts, disconnect the battery cables and retest.
•
If the analyzer does not power up when the PRINT/VIEW button is
pressed, replace the 9-volt battery.
