KOEO/KOER SELF-TEST
• The self-test function consists of the KOEO (Key On, Engine Off) self-test, performed when the ignition switch
is at ON, and the KOER (Key On, Engine Running) self-test, performed when idling. If an abnormality is
detected as either self-test is eecuted, a is displayed on the WDS or equivalent. Using the self-test function,
the present malfunction or a successful repair is readily confirmed. Refer to the self-test function table for the
corresponding DTCs.
KOEO (Key ON, Engine Off) self-test
— The KOEO self-test is a powertrain control system self-diagnosis, performed when the ignition switch is at
ON and the engine is stopped. A KOEO self-test begins when the connected WDS or equivalent sends an
eecute command to the PCM.
— As the KOEO self-test is performed, the PCM performs inspection for the set DTCs and if a malfunction is
detected the DTC is displayed on the WDS or equivalent.
KOER (Key ON, Engine Running) self-test
— The KOER self-test is a powertrain control system self-diagnosis, performed when the ignition switch is at
ON and the engine is idling. A KOER self-test begins when the connected WDS or equivalent sends an
eecute command to the PCM.
— As the KOER self-test is performed, the PCM performs inspection for the set DTCs and if a malfunction is
detected the DTC is displayed on the WDS or equivalent.
