MODE 6 REFERENCE TABLE

The engine control module (ECM) monitors the condition of emission control system.
By selecting MODE 6 using scan tool, Test Result and Limit Value (minimum) *1 or (maximum) *2 about the
main items of emission control system which ECM monitors can be confirmed. The value at the last monitor-
ing is output by ECM as a test result.

by the pressure difference
of intake manifold between
before and after
introduction of EGR using
the manifold absolute
pressure sensor.

× 0.0117 kPa

VVT Monitor Bank 1 (L4-IN)
Cam Phase Angle Deviation
(between target and actual
position)

ECM monitors the deviation
between the intake
camshaft target phase
angle and the intake
camshaft actual phase
angle.

× 0.01°

VVT Monitor Bank 2
(L4-EX)
Cam Phase Angle Deviation
(between target and actual
position)

ECM monitors the deviation
between the exhaust
camshaft target phase
angle and the exhaust
camshaft actual phase
angle.

× 0.01°

EVAP Monitor (Cap off)
Pressure drop during
de-pressurizing

ECM monitors the leak of
fuel evaporation gas by
checking whether the
pressure can be reduced
(the amount of pressure
reduction) using the fuel
tank differential pressure
sensor after sealing the fuel
tank and the fuel line.

× 0.0117 kPa

EVAP Monitor (0.040")
Pressure rise during airtight
condition

After ECM vacuumizes the
fuel tank and the fuel line
and then the specified time
is passed, ECM monitors
the leak of fuel evaporation
gas through the fuel tank
differential pressure sensor
to check the reduction of
vacuum in the fuel tank.

EVAP Monitor (0.020")
Pressure rise during airtight

gas through the fuel tank
differential pressure sensor
to check the reduction of
vacuum in the fuel tank.

NOTE: *1: Minimum value: The test fails if test value is less than this value.
NOTE: *2: Maximum value: The test fails if test value is greater than this value.
NOTE: When not finishing the monitor of the driving cycle for the request of On-Board Monitoring Test
Request, the ECM outputs the stored latest monitor test result.
NOTE: When the monitored test results are erased by the battery disconnection and so on, the ECM outputs
the values in hexadecimal of "0000" or "FFFF", otherwise it outputs abnormal values and so on. In case of
this, the ECU outputs are handled as invalid-values. When the first monitor (Readiness Status) is completed
after this, the ECM outputs the valid-values.
NOTE: "Test Limit Type & Component ID byte" output from the ECM is given in hexadecimal of "00" or "80".
"00" means the maximum value and "80" means the minimum value.
