Toyota Highlander Owners Manual / Maintenance and care / Maintenance / Emission inspection and maintenance (i/m) programs

Some states have vehicle emission inspection programs which include obd (on board diagnostics) checks. The obd system monitors the operation of the emission control system.

If the malfunction indicator lamp comes on

The obd system determines that a problem exists somewhere in the emission control system. Your vehicle may not pass the i/m test and may need to be repaired. Contact your toyota dealer to service the vehicle.

Your vehicle may not pass the i/m test in the following situations:

When the malfunction indicator lamp still remains on after several driving trips

The error code in the obd system will not be cleared unless the vehicle is driven 40 or more times.

If your vehicle does not pass the i/m test

Contact your toyota dealer to prepare the vehicle for re-testing.
