Lost Communication With Digital Disc Player/Changer Module D

Definition source: General OBD-II reference catalog
Definition verification: Not independently verified for display.
Time: Varies by diagnosis and vehicle | Diagnostic difficulty: Medium
Low Severity

A vehicle control module has detected that it is not receiving expected communication from Digital Disc Player/Changer Module D. This module is part of the vehicle’s media system, so the fault may affect disc playback or related infotainment features. The code does not by itself prove that the player/changer module has failed, and some vehicles may not have this equipment.

⚠️ Before You Begin (Safety First)

This communication fault is generally not a direct safety concern if the vehicle otherwise operates normally. Stop driving when it is safe to do so if other warning lights, loss of vehicle controls, or drivability problems occur; have those symptoms assessed promptly.

Common Symptoms

  • Disc playback or changer functions may be unavailable if the module is fitted and the communication loss affects its operation.
  • The media system may show a module-unavailable message or have limited functions, depending on the vehicle.
  • There may be no noticeable symptoms if the equipment is absent or the fault does not affect features the driver uses.
  • Other communication-related warnings or infotainment problems may occur if the underlying network issue affects additional modules.

Common Causes

  • The digital disc player/changer module may have lost power or ground.
  • A loose, damaged, or corroded connector or wiring fault may interrupt communication.
  • A fault in the vehicle communication network may prevent messages from reaching or leaving the module.
  • The module itself may be faulty, but the code alone does not establish that it needs replacement.
  • A configuration, software, or prior service issue may affect module communication.

Diagnostic Steps

  1. Check the owner’s manual or vehicle equipment information to see whether a digital disc player/changer is fitted; this helps determine whether the code applies to installed equipment.
  2. Note any infotainment problems and other warning lights or symptoms, since related faults can help identify whether the issue is limited to the media system.
  3. With the vehicle safely parked, visually check accessible media-system wiring and connectors for obvious looseness or damage. Do not pull on wiring or probe network circuits.
  4. Check relevant fuses only as described in the owner’s manual, and replace a fuse only with the specified type and rating. If it blows again, seek diagnosis rather than installing another fuse repeatedly.
  5. If the code returns or other systems show communication faults, arrange a scan of all modules and vehicle-specific electrical testing before replacing parts.

When to Call a Professional

Confirm that the vehicle is equipped with this module and check for related codes across all control modules. A technician can assess communication status and network wiring, then verify the module’s power, ground, connectors, and network connections using vehicle-specific service information before considering module replacement.

Commonly Asked Questions

Does U0190 prove the disc player/changer module has failed?

No. It indicates lost communication, which can result from a power, ground, connector, wiring, network, configuration, or module problem. Testing is needed to identify the cause.

Can this code appear if my vehicle has no disc player or changer?

Equipment and module availability vary by vehicle. Confirm the vehicle’s equipment and configuration before assuming a component is missing or faulty.

Can I keep driving with this code?

If the vehicle drives normally and only media functions are affected, the code is generally not a direct driving-safety issue. Stop when safe and seek prompt assessment if other warnings, control problems, or drivability symptoms occur.

Why should other modules be scanned too?

Additional communication codes can help distinguish a problem limited to this media module from a wider network, power, or wiring issue.
