Transmitter ID1 not Received (Test Mode DTC) - Tire Pressure Monitoring (from 12/2010)

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2121/21-C2125/25,C2181/81-C2185/85: No Signal from Transmitter ID1

C2185/85 - Transmitter ID5 not Received (Test Mode DTC)

DESCRIPTION

The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the air pressure of the tires. The measured

values are transmitted to the tire pressure warning antenna and receiver on the body as radio waves and then sent to the tire pressure warning ECU.

The ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this

threshold, the warning light in the combination meter comes on.

The tire pressure warning valve and transmitters constantly send radio waves to the tire pressure warning antenna and receiver.

Under the following conditions below, the tire pressure warning antenna and receiver is unable to receive the signals from the tire pressure warning

valves and transmitters, and a DTC is stored.

* Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.

* Devices using similar radio frequencies are used in the vehicle.

* The ID of the tire pressure warning valve and transmitter is mistyped during registration.

* A tire/wheel transmitter from a different vehicle is installed.

HINT

When no transmitter ID is received from a tire pressure warning valve and transmitter for a total of 20 minutes while the vehicle

speed is more than 8 km/h (5 mph) or no transmitter ID is received from the all the tire pressure warning valve and transmitters

for a total of 20 minutes, DTCs are stored.

DTCs from C2121/21 to C2125/25 can only be cleared by using the Techstream. DTCs from C2181/81 to C2185/85 can be cleared

when the transmitter in the tire pressure warning valve and transmitter sends a forced transmission signal or test mode ends.

DTCs from C2181/81 to C2185/85 are output only in test mode.

NOTICE:

When DTCs C2121/21 to C2125/25 are stored in the tire pressure warning ECU, DTC C2173/73 may be stored simultaneously. In

such cases, troubleshoot C2173/73 first, then troubleshoot DTCs C2121/21 to C2125/25.

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.
