Description and operation
| Description |
| • |
PDW consists of 8 sensors (front : 4 units, rear : 4 units) that are used to detect obstacles and transmit the result in three separate warning levels, the first, second and third to IBU via LIN communication. |
| • |
IBU decides the alarm level by the transmitted communication message from the slave sensors, then operates the buzzer or transmits the data for display. |

System Operation Specification
| Initial mode |
| 1. |
System initializing time
|
| 2. |
PDW recognizes LID and sets the sensor ID up during initialization. |
| 3. |
PDW activates each sensor and then executes the diagnosis after finishing initialization of IPM(IBU). |
| 4. |
PDW starting buzzer is normally worked, when sensor does not send an error message and after finishing error diagnosis. |
| 5. |
If any failure is received from the any sensors, PDW starting buzzer does not work but the failure alarm is operated for a moment. If you have display option, warning sign is also displayed.
|
| 6. |
IBU memorizes the completed initializing status of sensor. |
| Normal mode |
| 1. |
PDW-F : Lin communication starts and keeps the routine after IGN1 ON+D gear + below 15 km/h. PDW-R : Lin communication starts and keeps the routine after IGN1 ON+R gear |
| 2. |
After initializing, the routine starts at once without PDW starting warning sound. |
| 3. |
The obstacle alarm has 3 levels in 1, 2 and 3 step levels; alarms 1 and 2 have intermittent audible sounds, while alarm 3 has continuous audible sound. For the front ultrasonic sensor level 1 alarm does not exist. |
| 4. |
In display, the data of each sensor is sent from IBU to display, for example cluster. |
| 5. |
The efficient vehicle speed of PDW operation is under 10Km/h. |
| 6. |
Operation doesn't start or stop in N or P gears. |
