Detonation Elimination Technology (DET)

When DET senses and takes action to reduce detonation, the driver may notice a drop in engine RPM and/or reduced performance.

The ECU will illuminate the check engine LED and display “DETONATION” on the LCD screen whenever the DET system is active.

If the ECU determines the detonation cannot be controlled by normal means, and further operation may cause engine damage, the check engine LED will flash, the instrument clusters will display “DETONATION” and the ECU will either limit the maximum engine speed or turn off the engine.

If the ECU limits RPM, the limit will remain active until the driver stops and restarts the engine.
