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.

Problem symptoms tableVehicle speed signal error (test mode dtc)
Description
The tire pressure warning ecu receives a speed signal from the combination
meter. This dtc is stored
upon entering test mode, and cleared when a vehicle speed signal of 12 mph (20
km/h) is detected for 3
seconds or more. The dtc is output only in test mode.

Lost communication with front satellite sensor bus lh
Description
The front airbag sensor lh consists of the diagnostic circuit and the frontal
deceleration sensor.
If the center airbag sensor receives signals from the frontal deceleration
sensor, it determines whether or
not the srs should be activated.
