NOTE: This function reads off the real time data of
emission-related monitoring systems readiness status. Once the scan
tool has finished other operations, for example, clearing trouble
codes, the I/M Readiness Monitor Status program resets status of all
the monitors to “INC” condition. In order to set these monitors to a
Ready status, the vehicle must be driven through a complete drive
cycle. Times for reset vary depending on vehicle. Please refer to
vehicle service manual for drive cycle information.
NOTE: In this function, only ESC button is available. The other
buttons are disabled to prevent misoperation.
