Description
The tire pressure warning valve and transmitter constantly sends radio waves to the tire pressure warning ecu.
Under the following conditions, the tire pressure warning antenna and receiver is unable to receive the signals from the tire pressure warning valve and transmitter, and a dtc is output.
Dtcs c2121/21 to c2125/25 can only be deleted by the tester. Dtcs c2181/81 to c2185/85 can be deleted when the transmitter sends a forced transmission signal or the test mode ends. Dtcs c2181/81 to c2185/85 are output only in the test mode.
Hint:
When no signals are received for 60 minutes or more, a dtc is output.
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:
It is necessary to register an id code after replacing the tire pressure warning valve and transmitter and/or the tire pressure warning ecu (see page tw-9).

Hint:
This dtc relates to the thermostat.
Description
This dtc is set when the engine coolant temperature (ect) does not reach 75°c
(167°f) despite
sufficient engine warm-up time having elapsed.

For vehicles equipped with catalytic converter caution:
If a large amount of unburned gasoline or gasoline
vapors flow into the converter, it may cause
overheating and create a fire hazard. To prevent this,
observe the following precautions.
Use only unleaded gasoline.
Avoid idling the engine for more than 20 minutes.
