Polaris 2003 800 RMK Vertical Escape - Manual (Page 2)

-- 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 deto-
nation 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 igni-
tion 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 Solution
Poor quality fuel Replace with higher quality fuel
Improper jetting Verify and adjust per jetting chart
Improper engine modifications Do not modify the engine
D.E.T. FLASH SIGNALS
Use this chart to determine the meaning and course of action for each D.E.T. flash signal.
Type of Flash Cause Action
3 flashes of 1 second each Detonation See DET Troubleshooting Chart
Solid 3-second flash, off 1 second,
repeats until engine is shut down
Faulty sensor See your Polaris dealer
Solid non-blinking light High water temperature See your Polaris dealer. NOTE: If temporary opera-
tion is unavoidable, drive slowly and stop the engine
frequently to allow the engine to cool.
