INSPECTION PROCEDURE

NOTICE:
- When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using 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 if the ECU and/or valve and transmitters have been replaced.
PROCEDURE

1. CHECK FREQUENCY RECEIVING CONDITION

(a) Check if the vehicle is located in an area such as 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 an area described above, the tire pressure warning light may turn on only in a particular area due to interfering radio frequencies.

(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 transmission may be interrupted due to the 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 engine switch off.

(b) Connect Techstream to the DLC3.

(c) Turn the engine switch on (IG) and turn the tester on.

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

(e) Check the values by referring to the table below.

Tire Pressure Monitor





HINT
- *: It may take about 2 or 3 minutes until the values are displayed.
- When the "ID Tire Inflation Pressure" data has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then rapidly release the tire pressure and recheck the data.
