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.

The most likely causes of severe detonation are outlined in the troubleshooting
table on page 154.
The PIDD alert indicates which cylinder is experiencing detonation
OIL PUMP FAILURE PROTECTION (IF EQUIPPED)
If the ECU determines there is a problem with the electronic oil pump control
circuit, the engine management system will limit engine speed to approximately
4000 RPM and illuminate the check engine indicator light on the instrument
cluster or PIDD.
