Hint:
The dtcs for other inspection items may not be erased when only a certain signal is inspected.



Hint:
After completing the signal check for each inspection item, the dtcs that are determined normal by the tire pressure warning ecu will be erased. The dtcs for other inspection items may not be erased when only a certain signal is inspected.


Hint:
The transmitter id can be transmitted by rapidly reducing the tire pressure.
Hint:
After the signal check is completed, check for a
dtc and signal check dtc to confirm the system
status.

After completing test mode (signal check), turn the ignition switch off and disconnect the tester.
Dtc of signal check (test diagnosis) function: If a malfunction code is displayed during the test mode dtc check, check the circuit listed for that code. For details of each code, refer to the "see page" of the "dtc no." In the chart.
