EFI Diagnostic Mode
NOTE: The EFI diagnostic mode is intended to
quickly view fault codes stored in the EFI unit.
Polaris dealers are equipped with the proper
diagnostic tools to further diagnose the blink codes.
To recall blink codes (fail codes) from the ECU:
1. Verify the ATV key switch is off and the transmission
is in park.
2. Turn the key switch ON and OFF 3 times within 5
seconds and leave the key switch in the ON position
on the third turn.
3. The word “Wait” will appear, the ECU is now searching
for blink codes. READ AND RECORD THE NUMBER
OF FLASHES OF THE ‘MIL’ (Check Engine) LIGHT.
Codes ‘12’ and ‘61’ indicate the beginning and end of
the check sequence.
NOTE: The ‘check engine’ icon (mil) will flash the
codes during this mode. Record the flash
sequences.
4. The word “End” will display after all of the codes have
been displayed.
