KOEO/KOER SELF-TEST

A6E397018881T07

• 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 executed, 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

execute 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

execute 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.
