MODE 6 REFERENCE TABLE
The engine powertrain control module (ECM) <M/T> or powertrain control module (PCM) <A/T> 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 <M/T> or PCM <A/T> monitors can be confirmed. The
value at the last monitoring is output by ECM <M/T> or PCM <A/T> as a test result.
