KOEO/KOER SELF-TEST [13B-MSP]

• The self-test function consists of the KOEO (Key On, Engine Off) self-test, performed when the ignition switch is turned to the ON position and the engine is stopped, and the KOER (Key On, Engine Running) self-test, performed when idling. If an abnormality is detected when either self-test is executed, a DTC is displayed on the M-MDS. 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.

• The KOEO self-test is a powertrain control system self-diagnosis, performed when the ignition switch is turned to the ON position and the engine is stopped. A KOEO self-test begins when the connected M-MDS sends an execute command to the PCM.

• As the KOEO self-test is performed, the PCM performs the inspection for set DTCs and if a malfunction is detected the DTC is displayed on the M-MDS.

• The KOER self-test is a powertrain control system self-diagnosis, performed when the ignition switch is turned to the ON position and the engine is idling. A KOER self-test begins when the connected M-MDS sends an execute command to the PCM.

• As the KOER self-test is performed, the PCM performs the inspection for set DTCs and if a malfunction is detected the DTC is displayed on the M-MDS.
