Tire Pressure Warning System (Registration)

It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU.

Prepare all transmitter ID data before starting registration.

1. Before registration
   1. In case of tire pressure warning ECU replacement:
      • Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
      • If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.
   2. In case of tire pressure warning valve and transmitter replacement:
      • Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
