TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: REGISTRATION; 2013 MY FR-S [03/2012 -]

1. BEFORE REGISTRATION

NOTICE:
The transmitter ID is written on the tire pressure warning valve and transmitter. It is not possible to read the transmitter ID after installing the tire onto the wheel. Therefore, make a note of the transmitter ID before installing the tire.

(a) In case of door control receiver replacement:

(1) Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.

(2) If reading the stored transmitter IDs is impossible due to malfunctions of components such as the door control receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.

(b) In case of tire pressure warning valve and transmitter replacement:

(1) Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.









2. REGISTER TRANSMITTER ID (USING THE TECHSTREAM)

HINT
* The previously registered IDs will be cleared from memory when the registration is completed.
* If the ID registration step is not completed within 300 seconds, ID registration will be canceled.

(a) Set the air pressure of all tires to the specified value(s) Service Precautions.

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON and the Techstream on.

(e) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.

3. CONFIRMATION OF TRANSMITTER ID REGISTRATION

NOTICE:
* It may take up to a few minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121 to C2124 C2121.
* If the IDs have not been registered, DTC C2171 is stored in the door control receiver after 3 minutes or more.
* If normal pressure values are displayed, the IDs have been registered correctly.
* If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
* After all IDs are registered, DTC C2126 is stored in the door control receiver and the tire pressure warning light blinks for 1 minute and then illuminates. When the door control receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126 is cleared and the tire pressure warning light goes off.

(a) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

(b) Read the "ID Tire Inflation Pressure" values.

(c) Confirm that the tire pressure data of all tires (except the spare tire) is displayed on the Techstream screen.
