Monitor the parameters of 4 active WE sensors data.
Specification : the parameters related to 4 active WE sensors are displayed normally.
Fig.1) Sensor current data (normal)
TPMS Receiver is located in the back side of center console. The operating battery of TPMS module is supplied from the vehicle battery. Data such as Tire pressure, Tire Temperature, TPMS sensor battery status and TPMS sensor valve ID from TPMS sensors are transmitted to TPMS receiver in the form of RF signal. TPMS module accomplishes Tire Monitoring and Warning Logic with received data.
This DTC indicates that a commumication failure is occurred between micro controller and RF receiver in the TPMS ECU. In such a case no WE sensor data can be received/processed by the TPMS algorithm.
Item | Detecting Condition | Possible cause |
DTC strategy | ● LF/RF check | ● A failure RF Interference from external sources |
Enable conditions | ● All 4 active WE sensors are mute | |
Threshold value | ● No telegrams received for the last scheduled 8 transmissions from all 4 active WE sensors. ● The Innovative receiver (IRX) does not respond. | |
Mil On conditon | ● Active DTC is set |
Park the vehicle on a level surface.

Are the parameters normal?
▶ Fault is intermittent. It has been repaired and TPMS receiver module memory is not cleared yet.
▶ Go to "Verification of vehicle Repair" procedure.
▶ Substitute with a known-good TPMS receiver module and check for proper operation.
▶ If the problem is corrected, replace TPMS receiver module and then go to "Verification of Vehicle Repair" procedure.
After a repair, it is essential to verify that the fault has been corrected.
Connect TPMS exciter or scantool and select "Diagnostic Trouble Codes(DTCs)" mode
Using a TPMS exciter or scantool, Clear DTC.
Operate the vehicle within DTC Enable conditions in General information.
Are any DTCs present ?
▶ Go to the applicable troubleshooting procedure.
▶ System performing to specification at this time.
