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 radio receiver assembly and stereo component amplifier assembly, there may be a problem between the master unit and radio receiver assembly. (Refer to the illustration.)

HINT: Titles for each unit are stated in the following order: part name (physical address) [Name indicated by DTC]

1. MULTI-DISPLAY (physical address: 110) [EMV]




a. Logical address: 01 (Communication control)




b. Logical address: 34 (Front monitor)

2. NAVIGATION ECU (Physical address: 178) [NAVI]







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: 58 (Navigation): 80 (GPS)

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

3. RADIO RECEIVER ASSEMBLY (Physical address: 190) [AUDIO H/U]




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: 01 (Communication control)







c. 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.







4. NETWORK GATEWAY ECU (Physical address: 1C6) [G/W]
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) [DSP AMP]

NOTE: The following inspection procedures of the stereo component amplifier assembly are described on the assumption that the radio receiver assembly is normal. If any radio receiver assembly DTC is output, first proceed with troubleshooting of the radio receiver assembly. (Refer to step 3.)







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. CLOCK ASSEMBLY (Physical address: 1D6) [CLOCK]







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.




7. 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.
