TROUBLESHOOTING
Beeper Codes
Beeper codes are used to inform you on the DESS system operation or any en-
gine management system malfunctions as a complement of the pilot lamps to
catch your attention if an anomaly occurs or to inform you of a particular condi-
tion.
For more details on DESS system beeper codes, refer to DESS PILOT LAMP
CODES in TETHER CUT-OUT SWITCH .
For more details on gauge pilot lamps, refer to GAUGE PILOT LAMPS .
For any beep code not listed in this Operator's Guide, refer to an authorized
SKI-DOO dealer.
