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).
|
|
DTC Warning
|
1. |
Turn on condition
| A. |
When the system detects a fault that is external to the
receiver / sensor.
|
| B. |
When the system detects a receiver 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 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.
|
| 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 according to which has the most
likely cause.
|
| C. |
Maximum fault store is equal to 15.
|
| D. |
Certain faults are not covered through DTC. The main ones
are:
|
| 1) |
Receiver Micro-controller lock up ; requires observation
of lamps at Ignition ON to diagnose.
|
| 2) |
Ignition Line stuck ; requires observation of
lamps at Ignition ON to diagnose.
