DIAGNOSTIC TROUBLE CODE CHART
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| 01-D5 *1, *5 | Device that the sub-code shows is (was) disconnected from system when turning engine switch on (ACC) or on (IG) Communication condition with device that code shows cannot be obtained when engine starts | Inspection for device indicated by sub-code (Refer to inspection list for device indicated by sub-code) |
| 01-D8 *2, *5 | Device indicated by the sub-code is (was) disconnected from system after engine start | |
| 01-D9 *1, *5 | Device (for audio visual system) that had functioned before engine stopped is (was) disconnected from system when engine switch is (was) in on (ACC) or on (IG) | |
| 01-DA *5 | No response is identified when changing mode (audio and visual mode change) Detected when sound and image do not change by switch operation | |
| 01-DB *1, *5 | This code detects dual alarm | |
| 01-DC *3, *5 | This code indicates transmission failure to device indicated by sub-code NOTE: This DTC may not be related to malfunction | |
| 01-DE *4, *5 | This code is stored when slave device has been disconnected after engine start |
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 engine is started, idled for 60 seconds, turned off, and then started again.
- *4: This code may be stored if the engine is started, turned off, and then started again.
- *5: If the device is reported as not existing during verification, check the power source circuit and AVC-LAN circuit for the device.
- READ OUTPUT DTC (LAN MONITOR)
- Read the communication diagnostic check result (see DTC CHECK / CLEAR
).
