Causes

Fault reported by DVD/infotainment unit or head unit
Loss of communication between head unit and body/CAN gateway
Damaged or loose connector(s) at the head unit or amplifier
Blown fuse or power supply issue to the infotainment/DVD unit
Software/configuration or coding mismatch after a module replacement or update
Internal failure of the DVD drive, optical mechanism, or control electronics

Symptoms

DVD drive will not read discs or will not eject
No audio/video output from the DVD source
Infotainment display shows error message related to DVD or source unavailable
Intermittent or permanent loss of DVD functionality
Stored B119D (manufacturer-specific) fault and possibly related network communication U-codes
Infotainment/navigation system reboots or behaves erratically

What to check

Retrieve full DTC list and freeze frame data with a capable VCI and dealer-level tool (record all related B- and U-codes)
Check for related network communication codes (U-codes) which may indicate a CAN gateway or module comms issue
Verify vehicle battery voltage and charging system (low voltage can corrupt modules)
Visually inspect connector(s) at the head unit, amplifier and DVD drive for corrosion, bent pins or loose fit
Check relevant fuses for the infotainment/DVD unit and replace if blown
Check wiring harness for chafing, damage or recent service work in the dash area

Signal parameters

Infotainment unit supply voltage (battery voltage range, typically 11–14.5 V)
Ground continuity at head unit chassis ground
CAN bus presence and voltage levels on CAN High/Low lines (idle ~2.5 V differential)
LIN bus presence if LIN controlled peripherals are used
Optical drive motor current (if measurable) or drive spin-up response
Module response to diagnostic poll (OK / timeout / no response)

Diagnostic algorithm

Connect diagnostic tool with manufacturer-level capability; read and record all stored B- and U-codes and freeze frame data. Note occurrence conditions.
Confirm whether the code is permanent or pending. Clear codes and attempt to reproduce with controlled DVD operation (insert/eject disc, switch to DVD source).
Check battery voltage and charging system before proceeding — low voltage can create false faults.
Inspect head unit area: remove trim and verify connectors, antenna leads, and ground points are secure and undamaged.
Check fuses and power pins for the infotainment/DVD module; verify permanent +12V, switched +12V and accessory feed are present with ignition on/off as appropriate.
Use the diagnostic tool to request module information and verify the head unit responds to commands (play, eject). Check for firmware versions and module coding. Compare to known-good values or dealer specifications.
If communications faults are present (U-codes), trace CAN/LIN wiring for shorts/opens and check gateway module functionality.
If physical inspection and communications checks are good but the DVD mechanism fails to operate, consider removing the head unit and testing or replacing the DVD drive or head unit assembly. Prefer to bench-test or swap with a known-good unit where possible.
If module replacement or software update is performed, re-code/flash modules per OEM procedure and re-check for recurrence. If code persists after replacement and programming, escalate to OEM support or refer to Technical Service Bulletin.
Document findings, clear codes, and road/test the vehicle to confirm repair. If intermittent, consider adding monitoring to capture conditions when the fault occurs.

Likely causes

Poor connector/earth at the head unit or amplifier
CAN/LIN communication fault between modules
Software mismatch or missing module coding after service
Failed DVD drive or logic board in the head unit
Blown infotainment fuse or low battery voltage during operation

Fault status

⚠️ Status

Manufacturer-specific body code stored. Body/infotainment control module reports a fault relating to the DVD/infotainment unit (identifier: "Unique Disco - DVD"). Detailed meaning and repair instructions may require OEM diagnostic data, software update or module reprogramming.
