KOEO/KOER SELF-TEST [MZR-CD (RF Turbo)]

BME010200102T10
• The self-test function consists of the KOEO (Key On, Engine Off) self-test, performed when the engine 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 DTC 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 engine switch is at ON position and the engine is stopped. A KOEO self-test begins when the connected the 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 engine switch is at ON position and the engine is idling. A KOER self-test begins when the connected the 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.
