CAT
In this test all five gases HC, CO, CO2, NOx and O2 are analyzed to gauge the
performance of a Catalytic convertor. The test will report that the Catalytic convertor
is good, suspect or if the gas readings suggest there may be another fault which may
not be related to the Catalytic convertor (only available for 5-gas option).
Selecting petrol will start a sequence of screens, remaining memory, oil and coolant
levels, hand brake and engine running and up to temperature. HC Hangup sequence
will be started ending with a Zero Calibration and a prompt to insert probe into the
exhaust pipe. The process will continue with fast idle.
Open the throttle to increase engine speed to within the indicated RPM range.
