P2407 EVAP system leak detection pump sense circuit intermittent/erratic problem
•
The PCM monitors the pump load current (EVAP line pressure) when the evaporative leak monitor is operating.
If the change in pump load current is more than the specification while the PCM obtains the reference current
value 28 times, the PCM determines that there is an EVAP system leak detection pump sense circuit
intermittent/erratic problem.
•
The PCM monitors the pump load current (EVAP line pressure) when the evaporative leak monitor is operating.
If the pump load current is kept less than the maximum pump load current after the PCM obtains the reference
current value 28 times, the PCM determines that there is an EVAP system leak detection pump sense circuit
intermittent/erratic problem.
P2502 Charging system voltage problem
•
The PCM monitors the generator output voltage and the battery voltage when the engine is running. If the
generator output voltage is more than 16.9 V and the battery voltage is less than 10.9 V, the PCM determines
that there is a charging system voltage malfunction.
P2503 Charging system voltage low
•
The PCM monitors the generator output voltage when the engine is running. If the generator output voltage is
less than 8.5 V while the PCM needs more than 19.5 A from the generator, the PCM determines that the
charging system voltage is low.
P2504 Charging system voltage high
•
The PCM monitors the generator output voltage and the battery voltage when the engine is running. If the
generator output voltage is more than 18.4 V or the battery voltage is more than 15.9 V, the PCM determines
that the charging system voltage is high.

KOEO/KOER SELF-TEST
CHU010200102S04
•
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 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 turned
to the ON position 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 the inspection for 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 turned
to the ON position 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 the inspection for set DTCs and if a malfunction is
detected the DTC is displayed on the WDS or equivalent.
