DTC Code DTC Name
B15D6 Display Disconnected

DESCRIPTION

The accessory meter assembly (for 12.3 Inch) or multi-display (for 8 Inch) and multi-media module receiver assembly are connected by an AVC-LAN communication line.

When an AVC-LAN communication error occurs between the multi-media module receiver assembly and accessory meter assembly (for 12.3 Inch) or multi-display (for 8 Inch), these DTCs will be stored.

DTC Code DTC Detection Condition Trouble Area
B15D6* A device that is listed in the AVC-LAN connected device record of the master unit is missing.

  • Accessory meter assembly power source circuit*1

  • Multi-display power source circuit*2

  • AVC-LAN circuit

  • Accessory meter assembly*1

  • Multi-display*2

  • Multi-media module receiver assembly

Tech Tips


  • *: Even if no fault is present, this DTC may be stored depending on the auxiliary battery condition or hybrid control system start voltage.

  • The multi-media module receiver assembly is the master unit.
