In–32 – Introduction General Information 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 14 ° F and 95 ° F (–10 ° C and 35 ° C) Intake Air Temperature (IAT) is between 14 ° F and 95 ° F (–10 ° C and 35 ° C) Cold Soak Procedure has been completed Before starting the engine, the difference between ECT and IAT must be less than 13 ° F (7 ° C) Examples:
Scenario 1 ECT = 75 ° F (24 ° C) IAT = 60 ° F (16 ° C) Difference between ECT and IAT is 15 ° F (8 ° C) → The monitor will not run because difference between ECT and IAT is greater than 13 ° F (7 ° C) Scenario 2 ECT = 70 ° F (21 ° C) IAT = 68 ° F (20 ° C) Difference between ECT and IAT is 2 ° F (1 ° C) → The monitor will run because difference between ECT and IAT is less than 13 ° F (7 ° C) Drive Pattern (c) Connect the OBD II scan tool to the DLC3 to check monitor status and preconditions. NOTICE: Do not turn the ignition off until drive pattern is complete. (d) Release pressure in fuel tank by removing and then reinstalling the fuel tank cap.
(e) Start the engine and immediately begin driving as directed. NOTICE: Drive on smooth roads to minimize fuel sloshing. (f) Drive vehicle at approximately 45 mph (72 km/h) for about 5 minutes. (g) Drive vehicle at approximately 25 mph (40 km/h) for about 15 minutes and include a minimum of two stops for approximately 30 seconds. (h) The monitor should complete within approximately 20 minutes. If it does not, ensure preconditions are met, repeat step ”e”. 1996–2003 ADDITION OF OBD (OTH021U) 32 Author : Date:
