DIAGNOSTIC TROUBLE CODE CHART
| Terms | Description |
|---|---|
| Physical address | 3-digit, hexadecimal code assigned to all components connected to the AVC-LAN. Individual symbols are specified based on function. Units whose names are unknown or relevant units are displayed with physical addresses. |
| Logical address | 2-digit, hexadecimal code assigned to all the functions in the AVC-LAN system. |
HINT:
Titles for each unit are stated in the following order: parts name (physical address) [Name indicated by DTC]
- Radio and navigation assy (physical address: 140) [AVN]
- Logical address: 01 (Communication control)
HINT:
Methods used to verify the cause of the problem are listed in order of probability in the verification column.
