TPMS Reset Procedures: Notes

NOTE: The system will need to be initialized when tires are rotated; tires are replaced with tires of different pressures; tire pressure sensor and/or tire pressure monitor ECU are replaced. See INITIALIZING TIRE PRESSURE MONITOR SYSTEMΒ . When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized (registered) by the tire pressure monitor ECU prior to system initialization. See TIRE PRESSURE SENSOR REGISTRATIONΒ .

When tire pressure warning indicators do not go off, or come on while driving, check the tire pressure and adjust if needed. Reset after tire pressures have been adjusted is only necessary if the specified pressures are different than the ones previously set. Otherwise, ensure warning indicators go out after a brief period.
