2003 Polaris 800 RMK Vertical Escape Owners Manual - Page 2

DETONATION ELIMINATION TECHNOLOGY (D.E.T.) Your 2003 800 RMK Vertical Escape is equipped with a detonation sensor that monitors the engine and responds to detonation by automatically reducing the engine timing. When activated, the "DETONATION FLASH" indicator (A) will flash in the lower right-hand area of the tachometer. The activated sensor reduces engine detonation by retarding the ignition timing. This results in decreased engine RPM and performance. The detonation system is not always effective at sensing engine damaging detonation and protecting the engine under hot ambient conditions or conditions where the CDI box temperature is elevated. Under these types of conditions it is especially important to follow the jetting charts for temperature and altitude that are recommended for your engine. D.E.T. TROUBLESHOOTING Use this chart to determine causes and solutions for detonation. If none of these conditions exists and the sensor remains activated, see your Polaris dealer. Possible Cause Poor quality fuel Improper jetting Improper engine modifications Solution Replace with higher quality fuel Verify and adjust per jetting chart Do not modify the engine A D.E.T. FLASH SIGNALS Type of Flash 3 flashes of 1 second each Use this chart to determine the meaning and course of action for each D.E.T. flash signal.

NOTE: If temporary operation is unavoidable, drive slowly and stop the engine frequently to allow the engine to cool.
