Nissan Maxima: Readiness for inspection/maintenance (I/M) test

Nissan Maxima / Nissan Maxima Owners Manual / Technical and consumer information / Readiness for inspection/maintenance (I/M) test

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.

Turn the ignition switch ON 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. If the MIL indicates the vehicle is in a not ready condition, drive the vehicle through the following pattern to set the vehicle to the ready condition. If you cannot or do not want to perform the driving pattern, a NISSAN dealer can conduct it for you.
