2. CATALYST MONITOR (O2S TYPE)
(a) Preconditions
The monitor will not run unless:

MIL is OFF.

Engine Coolant Temperature (ECT) is 75°C (167°F) or greater.

Intake Air Temperature (IAT) is -10°C (14°F) or greater
NOTICE:
The readiness test can be completed in cold ambient conditions (less than -10°C / 14°F), if the drive
pattern is repeated a second time after cycling the ignition off.
(b) Drive Pattern
(1) Connect the OBD II scan tool to the DLC3 to check monitor status and preconditions.
(2) Drive the vehicle at 40 to 55 mph (64 to 88 km/h) for approximately for 3 minutes.
NOTICE:
Drive with smooth throttle operation and avoid sudden acceleration.
If IAT is less than 10°C (50°F) when engine was started, drive the vehicle at 40 to 55 mph (64 to 88
km/h) for additional 4 minutes.
(3) Drive the vehicle at 35 to 45 mph (56 to 72 km/h) for approximately 7 minutes.
NOTICE:
Drive with smooth throttle operation and avoid sudden deceleration as much as possible with the
throttle fully closed.
(4) If readiness status does not switch to complete, make sure that the preconditions are met and
the ignition switch is turned OFF and then repeat steps (2) and (3).
(5) Release pressure in the fuel tank by removing and then reinstalling the fuel tank cap.
(6) Start the engine and immediately begin driving as directed.

(a) Preconditions
The monitor will not run unless:

MIL is OFF

Fuel level is approximately 1/2 to 3/4

Altitude is 7,800 feet (2,400 m) or less*

Engine Coolant Temperature (ECT) is between 4.4°C and 35°C (40°F and 95°F)

Intake Air Temperature (IAT) is between 4.4°C and 35°C (40°F and 95°F)

Cold Soak Procedure has been completed

Before starting the engine, the difference between ECT and IAT must be less than 7°C (13°F)
HINT:
Examples:

Scenario 1
ECT = 24°C (75°F)
IAT = 16°C (60°F)
Difference between ECT and IAT is 8°C (15°F)
" The monitor will not run because difference between ECT and IAT is greater than 7°C (13°F)

Scenario 2
ECT = 21°C (70°F)
IAT = 20°C (68°F)
Difference between ECT and IAT is 1°C (2°F)
" The monitor will run because difference between ECT and IAT is less than 7°C (13°F)
The readiness test can be completed in cold ambient conditions (less than 40°F / 4.4°C) and/or at
high altitudes (more than 7,800 feet / 2,400 m) if the drive pattern is repeated a second time after cycl-
ing the ignition off.
(b) Drive Pattern
(1) Connect the OBD II scan tool to DLC3 to check monitor status and preconditions (refer to ºaº).
(2) Release pressure in fuel tank by removing the fuel tank cap and then reinstalling it.
(3) Start the engine and allow it to idle until ECT becomes 75°C (167°F) or higher.
(4) Run the engine at 3,000 rpm for about 10 seconds.
(5) Allow the engine to idle with the A/C ON (to create slight load) for 15 to 50 minutes.
NOTICE:
If the vehicle is not equipped with A/C put a slight load on the engine by doing the following :

Securely set the parking brake.

Block the drive wheels with wheel chocks.

Allow the vehicle to idle in drive for 15 to 50 minutes.
