DESCRIPTION
Each tire pressure warning valve and transmitter measures the internal temperature of its tire as well as tire pressure, and transmits the information to the tire pressure warning ECU and receiver along with the transmitter ID. If the measured temperature is out of the specified range, the tire pressure warning ECU and receiver recognizes it as a malfunction, outputs DTCs, and blinks the tire pressure warning light.

C2165/65 C2166/66 C2167/67 C2168/68 C2169/69 |
Temperature inside the tire exceeds 119°C (246.2°F) more than once. |
|
HINT:
It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC.
INSPECTION PROCEDURE
NOTICE:
- When replacing the tire pressure warning ECU and receiver, read the IDs stored in the old ECU using the intelligent tester and note them down before removal.
-
It is necessary to perform initialization

after registration
of the transmitter IDs into the tire pressure warning ECU and receiver after the ECU and/or valve and transmitter has been replaced.
PROCEDURE
|
1. |
CHECK TIRES |
(a) Check that the tires are not flat, and have no indication of air pressure drop.
OK:
Tires are normal.
HINT:
If a tire is damaged, the tire pressure warning valve and transmitter may also have been damaged at the same time.

REPLACE TIRE AND TIRE PRESSURE WARNING VALVE AND TRANSMITTER |
|
|
2. |
IDENTIFY TRANSMITTER CORRESPONDING TO DTC |
(a)
Set the tire pressure to the specified value
.
(b) Display the "TIREPRESS" data for each wheel using the intelligent tester.
(c) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm 2 , 5.8 psi) within 30 seconds.
(d) Check the DATA LIST.

HINT:
*: It may take about 2 or 3 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25
.
|
Condition |
Detection Condition |
|---|---|
|
One of "TIREPRESS" data (ID1 to ID5) changed. |
Normal |
|
No "TIREPRESS" data changed. |
Transmitter corresponding to DTC |
NOTICE:
- It takes about 2 or 3 minutes to display the updated tire pressure data.
- When no "TIREPRESS" data has changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then forcibly transmit the transmitter ID and recheck it.
- Record the transmitter ID and position of transmitters that are normal.
(e) When the "TIREPRESS" data (ID1 to ID5) has changed, repeat this procedure to identify the tire pressure warning valve and transmitter that corresponds to the DTC.
(f) When all of the "TIREPRESS" data (ID1 to ID5) has changed, identify the malfunctioning tire pressure warning valve and transmitter based on the recorded ID numbers and output DTC.
|
|
3. |
REPLACE TIRE PRESSURE WARNING VALVE AND TRANSMITTER |
(a)
Replace the identified tire pressure warning valve and transmitter with a new one
.
HINT:
- Before installing a new tire pressure warning valve and transmitter, read and write down its transmitter ID.
- The IDs for the tire pressure warning valve and transmitters that are not replaced should be checked using the tester and recorded.
|
|
4. |
CHECK REGISTRATION OF TRANSMITTER ID |
(a)
Register the transmitter ID for 5 wheels
.
|
|
