Key-On Engine-Running Tests
Standard Test
NOTE: The KOER Standard test can only be
done with the EST; MasterDiagnostics® software
is required.
During the KOER Standard test, the ECM commands
the IPR through a step test to determine if the ICP
system is performing as expected. The ECM monitors
signal values from the ICP sensor and compares
those values to the expected values.
Standard test is done, the ECM returns the engine to
normal operation and transmits DTCs set during the
test.
NOTE: Before doing this test, confirm the following
conditions:
•
Problems causing active DTCs were corrected,
and active DTCs were cleared.
•
Engine coolant temperature must be at least 70
°C (158 °F).
•
Battery voltage must be higher than 10.5 volts.
•
No signal from Vehicle Speed Sensor (VSS)
•
Transmission in park or neutral
