READINESS MONITOR DRIVE
PAT T E R N
1. PURPOSE OF READINESS TESTS
• The On-Board Diagnostic (OBD II) system is designed to
monitor the performance of emission related components,
and indicate any detected abnormalities with DTC
(Diagnostic Trouble Codes). Since various components
need to be monitored during different driving conditions,
the OBD II system is designed to run separate monitoring
programs called Readiness Monitors.
• The intelligent tester's software must be version 9.0 or
newer to view the Readiness Monitor Status. To view the
status, select the following menu items: DIAGNOSIS /
ENHANCED OBD II / MONITOR INFO / MONITOR
STATUS.
• When the Readiness Monitor status reads COMPL
(complete), the necessary conditions have been met for
running the performance tests for that Readiness Monitor.
• A generic OBD II scan tool can also be used to view the
Readiness Monitor status.
HINT:
Many state Inspection and Maintenance (I/M) programs
require a vehicle's Readiness Monitor status to show COMPL
before beginning emission tests.
The Readiness Monitor will be reset to INCMPL (incomplete)
if:
• The ECM has lost battery power or blown a fuse.
• DTCs have been cleared.
• The conditions for running the Readiness Monitor have not
been met.
If the Readiness Monitor status shows INCMPL, follow the
appropriate Readiness Monitor Drive Pattern to change the
status to COMPL.
CAUTION:
Strictly observe posted speed limits, traffic laws, and
road conditions when performing these drive patterns.
NOTICE:
These drive patterns represent the fastest method of
satisfying all conditions necessary to achieve complete
status for each specific Readiness Monitor.
In the event of a drive pattern being interrupted (possibly
due to factors such as traffic conditions), the drive
pattern can be resumed. In most cases, the Readiness
Monitor will still achieve complete status upon
completion of the drive pattern.
To ensure completion of the Readiness Monitors, avoid
sudden changes in vehicle load and speed (driving up
and down hills and/or sudden acceleration).

2. CATALYST MONITOR (ACTIVE AIR-FUEL RATIO
CONTROL TYPE)
(a) Preconditions
The monitor will not run unless:
• The MIL is OFF.
(b) Drive Pattern
(1) Connect the intelligent tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Turn the tester ON.
(4) Clear DTCs (if set) (see page ES-39).
(5) Start the engine and warm it up.
(6) Drive the vehicle at between 40 mph and 70 mph
(64 km/h and 113 km/h) for at least 10 minutes.
(c) Monitor Status
Check the Readiness Monitor status displayed on
the tester.
If the status does not switch to COMPL (complete),
extend the driving time.
3. EVAP SYSTEM MONITOR (KEY OFF TYPE)
(a) Preconditions
The monitor will not run unless:
– The fuel tank is less than 90% full.
– The altitude is less than 8,000 ft. (2,450 m).
– The vehicle is stationary.
– The engine coolant temperature is between
4.4
C and 35C (40F and 95F).

(b) Monitor Conditions
(1) Turn the ignition switch OFF and wait for 6
hours.
HINT:
Do not start the engine until checking Readiness
Monitor status. If the engine is started, the step
described above must be repeated.
(c) Monitor Status
(1) Connect the intelligent tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Turn the tester ON.
(4) Check the Readiness Monitor status displayed
on the tester.
If the status does not switch to COMPL (complete), restart the
engine, make sure that the preconditions have been met, and
then perform the Monitor Conditions again.

least 10 seconds.
(9) Soon after performing step (8) above, release
the accelerator pedal for at least 4 seconds without
depressing the brake pedal in order to execute fuel-
cut control.

speed declines to less than 10 km/h (6 mph).
(11) Repeat steps from (8) through (10) above at
least 3 times in one driving cycle.
(c) Monitor Status
(1) Check the Readiness Monitor status displayed
on the tester.
(2) If the status does not switch to COMPL
(complete), make sure that the preconditions
have been met, and then perform steps from (5)
through (11) in the Drive Pattern above.
