DIAGNOSTIC TROUBLE CODE CHART
AVC-LAN WIRING DIAGRAM
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)
HINT:
- *1: This code may be stored depending on the battery condition or engine start voltage even if no failure is detected.
- *2: If the power connector is disconnected after the engine starts, this code is stored after 180 seconds.
- *3: This code may be stored if the ignition switch is turned to the START position again with the engine running. (Key type ignition switch only)
- *4: This code may be stored if the ignition switch is held in the START position for 1 minute or more before returning to the ON position. (Key type ignition switch only)
- *5: If the device is reported as not existing during verification, check the power source circuit and AVC-LAN circuit for the device.
b. Logical address: 34 (Front monitor)
