TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: C2177/77: Initialization not Completed
C2177/77 - Initialization not Completed

DESCRIPTION

Initialization is necessary if one of the following occurs: 1) before delivery of a new vehicle; 2) after replacement of the tire pressure warning ECU; 3) after replacement of a tire pressure warning valve and transmitter; 4) specified tire pressure changes depending on the size or type of tire; 5) when changing the tire inflation pressure by changing traveling speed or load weight, etc.; or 6) rotating tires that have different specified tire pressures in the front and rear.





WIRING DIAGRAM

Refer to DTCs C2111/11, C2112/12, C2113 and C2114/14 C2111.

INSPECTION PROCEDURE

NOTICE:
* When replacing the tire pressure warning ECU, read the 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 have been replaced.

PROCEDURE

1. CHECK FREQUENCY RECEIVING CONDITION

(a) Check for the following conditions:

(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 illuminate only 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) C2121
