Hyundai Genesis: Tire Pressure Monitoring System / Description and Operation
Tread Lamp
| - |
Tire Under Inflation / Leak Warning. 
|
| 1. |
Turn-on condition
| A. |
When tire pressure is below allowed threshold |
| B. |
When rapid leak is detected by the sensor. |
|
| 2. |
Turn-off condition
| A. |
Under-inflation ; When tire pressure is above (warning threshold + hysteresis). |
| B. |
Rapid Leak ; When tire pressure is above (leak warning threshold). |
|
Wheel Location
| 1. |
Turn-on condition
| A. |
At the same time as TREAD Lamp. |
| B. |
Indicates wheel location where under inflation / leak has occurred. |
|
| 2. |
Turn-off condition
| A. |
At the same time as TREAD Lamp. |
|
If wheel locations change in between Ignition cycles, then
the system assumes the previous Auto-Located position. Once
Auto-Location figures out the position, the correct lamp will be lit. |
|
DTC Warning
| 1. |
Turn-on condition
| A. |
When the system detects a fault that is external to the receiver / initiator / sensor. |
| B. |
When the system detects a receiver fault. |
| C. |
When the system detects an initiator fault. |
| D. |
When the system detects a sensor fault. |
|
| 2. |
Turn-off condition
| A. |
If the fault is considered as 'critical', then the lamp is
kept 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 kept on until DTC demotion checking
is completed. |
| B. |
'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. |
|
System Fault
| 1. |
General Function
| A. |
The system monitors a number of inputs across time in order to determine that a fault exists. |
| B. |
Faults are prioritized by the causes. |
| C. |
The system stores up to 15 faults. |
| D. |
Certain faults are not covered through DTC. The main ones are: |
| 1) |
Sensor thermal shutdown (239°F/115°C) |
| 2) |
Ignition Line stuck ; requires observation of lamps at Ignition ON to diagnose. |
