Mode
| 1. |
Initial state
| • |
The receiver is a single component parts, replaced parts must
be initial state.
|
| • |
Platform information and ID sensor is not entered.
|
|
| 2. |
Normal operation states
| • |
To detect the tire pressure or DTC, the receiver must be in
normal operating condition.
|
| • |
Verify the location of sensor and information through receiver.
|
|
| 1. |
Normal operation
| • |
Once process is finished successfully, the ID of four sensors
or wheel location is entered to the memory device.
|
| • |
If there is pressure loss and air leakage until ending the automatic
learning, detect the previous learned sensor ID.
|
| • |
Does not appear spare tire inflation and DTC status.
|
|
| 2. |
General condition for learning new sensor.
| • |
The receiver automatically finds out the location of four sensors.
