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 DTCs (Diagnostic Trouble Codes).
Since various components need to be monitored in
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 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 broken 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).

• Vehicle was driven in the city area (or on free-
way) for 10 minutes or more.
(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 an intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Turn the tester or scan tool ON.
(4) Check the Readiness Monitor status displayed
on the tester or scan tool.
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.
4. A/F SENSOR AND HO2S MONITORS
(a) Preconditions
The monitor will not run unless:
• 2 minutes or more have elapsed since the engine
was started.
• The Engine Coolant Temperature (ECT) is 75
C
(167
F) or more.
• Cumulative driving time at a vehicle speed of 30
mph (48 km/h) or more exceeds 6 minutes.
• Air-fuel ratio feedback control is performed.
• Fuel-cut control is performed for 8 seconds or
more (for the Rear HO2 Sensor Monitor).
(b) Drive Pattern for front A/F sensor and HO2 sensor.
(1) Connect an intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Turn the tester ON.
(4) Clear the DTCs.
(5) Start the engine, and warm it up until the ECT
reaches 75
C (167F) or higher.
(6) Drive the vehicle at 38 mph (60 km/h) or more
for at least 10 minutes.
(7) Change the transmission to the 2nd gear.
(8) Accelerate the vehicle to 40 mph (64 km/h) or
more by depressing the accelerator pedal for at
least 10 seconds (Procedure "A").
(9) Soon after performing procedure "A" above,
release the accelerator pedal for at least 4
seconds without depressing the brake pedal, in
order to execute fuel-cut control (Procedure "B").
(10) Allow the vehicle to decelerate until the vehicle
speed declines to less than 6 mph (10 km/h)
(Procedure "C").
(11) Repeat procedures from "A" through "C" above
at least 3 times in one driving cycle.
