Drive Cycle Monitor
The Drive Cycle Monitor function is very similar to the I/M Monitors
though the Drive Cycle Monitor is used to view REAL TIME operations
of the Emissions System on OBD II vehicles.
Drive Cycle Monitor continuously updates as the vehicle reports
operations of the Emission System.
!
CAUTION
Two people must be in the vehicle when driving.
One to drive and the other to operate the Scan Tool.
Refer to the vehicle service manual for the drive cycle operation.
Drive Cycle Monitor can be used if you want to drive the vehicle until
all of the monitors are OK.
During normal driving conditions, the vehicle computer scans the
emission system. After a specific amount of drive time (each monitor
has specific driving conditions and time requirements), the
computer’s monitors will decide if the vehicle emissions system is
working correctly or not as well as detecting out a range of values.
When the monitor’s status is:
“ok” - vehicle has been driven enough for function.
“inc” (Incomplete) - vehicle was not driven enough to complete all of
the monitors.
“n/a” (Not Applicable) - vehicle does not support that monitor.
Clear Monitors by:
Erasing Codes.
Vehicle Computer Module losing power (on some vehicles).
