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.

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.

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.

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.
