Impreza WRX STI F4-2.5L DOHC Turbo (2007)
CONDITIONS JUDGED AS A FAILURE
The receiver decides that the system has failed when any of the following conditions is met.
-
EEPROM abnormal: The written data does not coincide with the loaded data when the ID is registered.
-
Data reception failure: Transmitter data could not be received for 10 minutes or more while driving at a speed exceeding 40 km/h (24.9 MPH).
-
Function code abnormal: "Re-measure" function code is received for 5 times in series, though the pressure change compared to the last data was
within 7 kPa (0.071 kgf/sq.cm, 1.02 psi) while driving at a speed exceeding 40 km/h (24.9 MPH).
-
Air pressure data abnormal: "FFH"* pressure data has been received for 5 times in series while driving at a speed exceeding 40 km/h (24.9 MPH)
.
-
Low battery: Function code for the "low battery" mode has been received for 20 times or more in series.
-
Vehicle speed sensor abnormal: Function code for the "wake" mode has been received while the vehicle speed signal is 6 km/h (3.7 MPH) or
lower.
*FFH is transmitted when the pressure data exceeds the upper limit (352kPa, 3.59 kgf/sq.cm, 51.05 psi) of pressure detection.
If the indicator comes ON due to low tire pressure, the indicator will turn OFF when the under-inflated tire is inflated to normal pressure.
