Indicates that tire needs to be re-inflated to placard pressure / repaired.
2.
Turn off condition
•
Under-inflation: When tire pressure is above warning threshold + hysteresis.
•
Rapid Leak: When tire pressure is above leak warning threshold.
DTC Warning
1.
Turn on condition
•
When the system detects a fault that is external to the receiver/ sensor.
•
When the system detects a receiver fault.
•
When the system detects a sensor fault.
2.
Turn off condition
•
If the fault is considered as ''critical'', then the lamp is
held on throughout the current Ignition cycle (even if the DTC has been
demoted). This is because it is important to bring the problem to the
driver''s attention. On the following Ignition cycle, the demotion
conditions will be re-checked. If the demotion conditions occur, the
lamp will be turned off. It will be held on until DTC demotion checking
is completed.
•
''Non-critical'' faults are those that can occur temporarily,
e.g., vehicle battery under voltage. The lamp is therefore turned off
when the DTC demotion condition occurs.
•
When driving in high altitude grades, it is natural for the
atmospheric pressure to decrease. Therfore, please check the tire
pressure and add more air as necessary.
•
Tire pressure can be decreased naturally due to decrease in
ambient temperature (especially in winter). In this case, fill tires
with air to the specification if warning lamp is illuminated as this is
natural phenomenon.
System Fault
1.
General Function
•
The system monitors a number of inputs across time in order to determine that a fault exists.
•
Faults are prioritized according to the most likely cause.
•
Certain faults are not covered through DTC. The main ones are:
a.
Sensor thermal shutdown (over 257°F/125°C).
b.
Stuck Ignition Line: Requires observation of lamps at ignition ON to diagnose.
