If ID Codes Are Not Registered Properly:

In the following situations, ID code registration may take longer than usual to be completed or may not be possible. Normally, registration completes within approximately 30 minutes.

• Vehicle is not parked for approximately 20 minutes or more before driving.
• Vehicle is not driven at approximately 25 mph (40 km/h) or more.
• Vehicle is driven on unpaved roads.
• Vehicle is driven on unpaved roads and transmitters of your vehicle over those of other vehicles.
• Wheel with tire pressure warning valve and transmitter installed is inside or near the vehicle.

If registration does not complete after driving for 1 hour or more, perform the ID code registration procedure again from the beginning.

• If the vehicle is reversed during registration, the data up to that point is reset, so perform the registration procedure again from the beginning.
• In the following situations, ID code registration will not be started or was not completed properly and the system will not operate properly. Perform the ID code registration procedure again:
  • If, when attempting to start ID code registration, the tire pressure warning light does not blink slowly 3 times.
  • If, when the vehicle has been driven for about 20 minutes after performing ID code registration, the tire pressure warning light blinks for approximately 1 minute and then illuminates.
  • If the ID codes cannot be registered even when performing the above procedure, see appropriate manufacturer service information.
