When tire pressure is above(warning threshold + hysteresis).
•
When tire pressure is above (leakwarning threshold).
DTC Warning
1.
Turn on condition
•
When the system detects a fault that is external to the receiver / initator / sensor.
•
When the system detects a receiver fault.
•
When the system detects an initiator 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
drivers 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 which has the most likely cause.
•
Maximum fault store is equal to 15.
•
Certain faults are not covered through DTC. The main ones are:
a.
Receiver Micro-controller lock up ; requires observation of lamps at Ignition ON to diagnose.
b.
Ignition Line stuck ; requires observation of lamps at Ignition ON to diagnose.
Description 1. Function • By detecting the pressure, temperature, acceleration, and battery condition, transmit information to ECU by a wireless RF. • Wheel location is recognized by comparing the ...
Removal 1. Turn the ignition switch OFF and disconnect the negative (-) battery terminal. 2. Disconnect the accelerator position sensor connector (A). 3. Remove the mounting nuts (B) and bolt (C), and then remove the accelerator pedal module. Installation 1. Install in the reverse order of removal. Accelerator ...
Inspection Radiator Cap Testing 1. Remove the radiator cap, wet its seal with engine coolant, and then install it on a pressure tester. 2. Apply a pressure of 93.16 ~ 122.58kPa (0.95 ~ 1.25kgf/cm?, 13.51 ~ 17.78psi). 3. Check for a drop in pressure. 4. If the pressure drops, replace the cap. Radiator ...
