Detonation Elimination Technology (DET)
The DET system prevents damage to the engine from
detonation by entering an engine protection mode
whenever the DET system is active.
When excessive detonation is detected, the check
engine light will illuminate. You may notice decreased
engine performance and RPM when the DET system is
activated. In most cases this is temporary and no action
is required. The engine will return to its normal
performance automatically.
If severe detonation occurs:
• The check engine light begins to flash steadily.
• The IDD displays “Detonation Detected - MAG (or
PTO)”.
• The engine enters DET latching (limp home) mode.
• On 2015 800 AXYS models, the ECU closes
exhaust valves to limit engine power in DET latching
mode. On all other 2015 AXYS and PRO-RIDE
models, the ECU will shut down the engine during
DET latching mode. In either event, restart the
engine to reset the mode.
• For all 2015 AXYS and PRO-RIDE models, the ECU
will shut down the engine during a critical overheat
condition.
