  2. Check all four wheels to make sure they are the TPMS type with the tire pressure sensor

    Is each wheel a TPMS type with a tire pressure sensor mounted on the vehicle? 

    YES  -Go to step 3

    NO  -Install a TPMS type wheel, and memorize the sensor ID Drive the vehicle above 15 mph (24 km/h) continuously for 40 seconds, or memorize the ID with the HDS (see MEMORIZING THE TIRE PRESSURE SENSOR ID )

  3. Test-drive the vehicle
  4. Check the VEHICLE SPEED in the TPMS DATA LIST with the HDS

    Is the vehicle speed indicated? 

    YES  -Go to step  10

    NO  -Go to step 5
