DTC C2141/41: Transmitter ID1 Error; DTC C2142/42: Transmitter ID2 Error; DTC C2143/43: Transmitter ID3 Error; DTC C2144/44: Transmitter ID4 Error [10/2013 - ]: Description
The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressures. 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.
When the internal circuit of the tire pressure warning valve and transmitter is malfunctioning, one of these DTCs is output.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| C2141/41 C2142/42 C2143/43 C2144/44 |
If an "ERROR" signal is received 3 times consecutively, the tire pressure warning valve and transmitter will be judged as defective and a DTC will be output. This will happen in situations where the inflation pressure is outside the range -100 to 538 kPa (-1.0 to 5.4 kgf/cm2 , -14 to 78 psi), the temperature inside the tire is outside the specified range -40 to 120°C (-40 to 253°F), or an error occurs in the tire pressure warning valve and transmitter or the surrounding area. |

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.
