FEATURES

Detonation Elimination Technology (DET)
The DET system prevents damage to the engine from detonation by
going into an engine protection mode whenever the DET system is
active. When excessive detonation is detected, the check engine light
will illuminate, flicker or flash momentarily..
Check Engine Light Status
Solid or Flickering
Flashing
You may notice decreased engine RPM and performance when DET is
activated, but in most cases DET activation is temporary, and the timing
will return to normal automatically.
If severe detonation occurs, the check engine light will begin to flash.
The engine will enter a limp home mode (and RPM will be limited to
6500 RPM) and stay in this mode until the engine is shut down and
restarted.
The most likely causes of severe detonation are shown in the table
below. Refer to the table for troubleshooting information.
