5.9 Drive Cycle Monitor
The Drive Cycle Monitor function is very similar to I/M
Monitors though the Drive Cycle Monitor is used to
view real-time operations of the emissions system on
OBDII vehicles. Drive Cycle Monitor continuously
updates as the vehicle reports operations of the emis-
sion system.
CAUTION
Two people must be in 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 monitors will
decide if the vehicle emissions system is working cor-
rectly or not as well as detecting out a range of values.
When the monitor 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.
Reset monitors by:
• Erasing codes.
• Vehicle computer module losing power (on some
vehicles).
From Diagnostic Menu:
1. Select Drive Cycle Monitor.
• Use the and keys until Drive Cycle
Monitor is highlighted.
• Press .
