C2177/77 - Initialization not Completed
DESCRIPTION
Initialization is necessary if one of the following occurs: 1) the ECU is replaced; 2) the tire pressure warning valve and transmitter is replaced; 3) tires with a different tire standard pressure are installed; 4) the tires are rotated on vehicles whose front and rear tire inflation pressure standard values are different; or 5) a new vehicle is delivered.
WIRING DIAGRAM
INSPECTION PROCEDURE
NOTICE:
* When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the Techstream and write them down before removal.
* It is necessary to perform initialization Initialization after registration Registration of the transmitter IDs into the tire pressure warning ECU after the ECU and/or valve and transmitter has been replaced.
PROCEDURE
1. CHECK FREQUENCY RECEIVING CONDITION
(a) Check if the vehicle is in conditions such as the ones described below:
(1) Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
HINT
If the vehicle is located in areas described above, the tire pressure warning light may blink for a minute and turn on in a particular area.
(2) Devices using similar radio frequencies are used in the vehicle.
OK:
Facilities, or devices that use similar radio frequencies are not located in the vicinity of the vehicle.
HINT
Radio frequency may be interrupted due to surroundings or devices installed by the user.
NG -- CHECK IF ANY DEVICE IS INSTALLED BY USER
OK -- Continue to next step.
2. PERFORM INITIALIZATION
(a) Perform initialization Initialization.
NEXT -- Continue to next step.
3. CONFIRM TIRE INFLATION PRESSURE (DATA LIST)
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON and turn the Techstream on.
(d) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(e) Check the values by referring to the table below.

HINT
* *: It may take about 5 to 6 minutes until the values are displayed.
* When no "ID Tire Inflation Pressure" has changed, rotate the tire 90 to 270°. Then recheck it.
