Tire pressure sensor ID registration is complete when the TPMS warning light is not illuminated. NOTE: If vehicle is driven within 15 minutes of changing tires, the warning light will flash because the sensor ID signal code would not have been registered. If this happens, park the vehicle for about 15 minutes, after which sensor ID signal code will register upon driving vehicle for 10 minutes or more.
