DIAGNOSTIC TROUBLE CODE CHART






HINT: Titles for each unit are stated in the following order: parts name, (physical address) and [name indicated on the DTC display].

1. Radio receiver assembly (physical address: 190) [AUDIO H/U]













a. Logical address: 01 (Communication control)

HINT:
- *1: This code may be recorded 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 recorded after 180 seconds.
- *3: This code may be stored if the ignition key is turned to the START position again with the engine running.
- *4: This code may be stored if the ignition key is held in the START position for 1 minute or more before returning to the ON position.
- *5: If the device is reported as not existing during verification, check the power source circuit and AVC-LAN circuit for the device.
- *6: w/ Rear seat audio system only.
- *7: w/ Rear seat entertainment system only.




Logical address: 01 (Communication control) continued

3. Multi-display controller sub-assembly (Physical address: 1F6) [RSE ECU, MAIN]







a. Logical address: 01 (Communication control)

HINT:
- *1: Even if no failure is detected, this code may be stored depending on the battery condition or voltage for starting an engine.
- *2: This code is stored when 210 sec. has passed after the power supply connector is pulled out after engine start.
- *3: This code may be stored when the engine key is turned back to the ON position and then turned again to the START position in 1 minute after engine start.
- *4: This code may be stored when the engine key is turned back to the ON position and then turned again to the START position after engine start.

4. Rear seat audio controller (Physical address: 1F4) [RSA]







a. Logical address: 01 (Communication control)

HINT:
- *1: Even if no failure is detected, this code may be stored depending on the battery condition or voltage for starting the engine.
- *2: When 210 sec. has passed after pulling out the power supply connector of the master component with the ignition switch in ACC or ON, this code is stored.
- *3: This code may be stored when the engine key is turned 1 min. again after engine start.
- *4: This code may be stored when the engine key is turned again after engine start.
