Readiness for Inspection/Maintenance (I/M) test

Readiness for Inspection/Maintenance (I/M) test  - Emission control system warranty - Technical and consumer information - Infiniti QX Owners Manual - Infiniti QX

A vehicle equipped with Four-Wheel Drive (4WD) should never be tested using a two wheel dynamometer (such as the dynamometers used by some states for emissions testing), or similar equipment. Make sure you inform test facility personnel that your vehicle is equipped with 4WD before it is placed on a dynamometer. Using the wrong test equipment may result in transmission damage or unexpected vehicle movement which could result in serious vehicle damage or personal injury. Due to legal requirements in some states and Canadian Provinces, your vehicle may be required to be in what is called the ready condition for an Inspection/Maintenance (I/M) test of the emission control system. The vehicle is set to the ready condition when it is driven through certain driving patterns. Usually, the ready condition can be obtained by ordinary usage of the vehicle. If a powertrain system component is repaired or the battery is disconnected, the vehicle may be reset to a not ready condition. Before taking the I/M test, check the vehicles inspection/maintenance test readiness condition. Place the ignition switch in the ON position without starting the engine. If the Malfunction Indicator Light (MIL) comes on steady for 20 seconds and then blinks for 10 seconds, the I/M test condition is not ready. If the MIL does not blink after 20 seconds, the I/M test condition is ready. Contact an INFINITI retailer to set ready condition or to prepare the vehicle for testing.
