DIAGNOSTIC TROUBLE CODE CHART






AVC-LAN WIRING DIAGRAM

HINT: If any DTCs are simultaneously output for 2 or more slave units that are connected in series, there may be a problem between the master unit and the slave unit which is closest to the master unit. Therefore, first proceed with troubleshooting of that slave unit.




For example, if DTCs are output for the multi-display and gateway ECU, there may be a problem between the master unit and multi-display. (Refer to the illustration.)

HINT: Titles for each unit are stated in the following order: part name (physical address)




1. RADIO RECEIVER ASSEMBLY (physical address: 190)
a. Logical address: 01 (Communication control)




b. Logical address: 62 (CD): 63 (In-dash CD changer)

HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.

2. GATEWAY ECU (Physical address: 1C6)

NOTE: The following inspection procedures of the gateway ECU are described on the assumption that the multi-display is normal.

If any multi-display DTC is output, first proceed with troubleshooting of the multi-display. (Refer to step 4.)







a. 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.







3. TAPE PLAYER ASSEMBLY (Physical address: 320)
a. 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.




b. Logical address: 61 (Cassette unit)

HINT: The numbers used to verify the cause of the problem are listed in order of probability in the verification column.




4. MULTI-DISPLAY (Physical address: 1D4)
a. 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.







5. STEREO COMPONENT AMPLIFIER ASSEMBLY (Physical address: 440)
a. 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.




6. THE INSPECTION LIST FOR THE DEVICE INDICATED BY THE SUB CODE

HINT:
- If any DTCs are output for 2 or more slave units that are connected in series, there may be a problem between the master unit and the slave unit which is closest to the master unit. Therefore, first proceed with troubleshooting of that slave unit.
- Methods used to verify the cause of the problem are listed in order of probability in the verification column.
