TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2165/65: Abnormal Temperature Inside ID1 Tire

DTC C2165/65 - Abnormal Temperature Inside ID1 Tire

DTC C2166/66 - Abnormal Temperature Inside ID2 Tire

DTC C2167/67 - Abnormal Temperature Inside ID3 Tire

DTC C2168/68 - Abnormal Temperature Inside ID4 Tire

DTC C2169/69 - Abnormal Temperature Inside ID5 Tire

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 along with the transmitter ID. If the measured temperature is out of the specified range, the tire pressure warning ECU recognizes it as a malfunction, outputs DTCs, and the tire pressure warning light blinks for 1 minute and then remains on.





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, read the IDs stored in the old ECU using the Techstream and note them down before removal.
- It is necessary to perform initialization (Programming and Relearning) after registration (Programming and Relearning) of the transmitter IDs into the tire pressure warning ECU after the ECU and/or the tire pressure warning 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.

NG -- REPLACE TIRE AND TIRE PRESSURE WARNING VALVE AND TRANSMITTER
OK -- Continue to next step.
2. IDENTIFY TRANSMITTER CORRESPONDING TO DTC (Service Precautions)

NEXT -- Continue to next step.
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 valves and transmitters that are not replaced should be checked using the Techstream and recorded.

NEXT -- Continue to next step.
4. PERFORM REGISTRATION OF TRANSMITTER ID
(a) Register the transmitter ID for all wheels (Programming and Relearning).
NEXT -- Continue to next step.
5. PERFORM INITIALIZATION
(a) Perform initialization (Programming and Relearning).
NEXT -- Continue to next step.
6. CONFIRM TIRE INFLATION PRESSURE (DATA LIST) (C2121)

A -- REPLACE TIRE PRESSURE WARNING ECU
