DESCRIPTION


DTC No.
DTC Detection Condition
Trouble Area
01-D5
*1, *5
Device that sub-code shows is (was) disconnected from system when turning the 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 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. *1: This code may be recorded depending on the battery condition or engine start voltage even if no failure is detected.
  2. *2: If the power connector is disconnected after the engine starts, this code is recorded after 180 seconds.
  3. *3: This code may be stored if the engine is started, idled for 60 seconds, turned off, and then started again.
  4. *4: This code may be stored if the engine is started, turned off, and then started again.
  5. *5: If the device is reported as not existing during verification, check the power source circuit and AVC-LAN circuit for the device.


INSPECTION PROCEDURE

1.READ OUTPUT DTC (LAN MONITOR)

  1. Read the communication diagnostic check result (Click here).
