Diagnostic Code Interpretation
Diagnostic codes are displayed through a series of light flashes and pauses. Count number of flashes and
pauses to interpret code.
Example: “Flash, flash, flash, pause, flash, flash, longer pause” represents code 32.
Tips for interpreting codes:
• In View All Codes mode, the green control cycle light will come on the first time the red diagnostic light
flashes a code. The green control cycle light will then go off and the red diagnostic light will flash the
code two more times.
• Codes are displayed from lower to higher numbers.
• Code 11 is not used.
• Code 12 signals successful entry into and exit from review mode.
IMPORTANT: Do not turn off ignition. Diagnostic codes are cleared each time ignition is turned off.
