Invalid Data from Digital Audio D Module
The control module that stored this code (typically the body control module, gateway, or the master infotainment module) has detected that data received from the Digital Audio Control Module D via the communication bus (CAN, LIN, MOST, or Ethernet) is invalid. This means the data frame arrived corrupted, with an incorrect checksum, a message counter out of sequence, or parameter values outside the expected range defined in the vehicle's communication matrix.
1. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
2. Most Common Causes
- Faulty wiring or connectors in the communication bus of the Audio D Module (short circuit, open circuit, high resistance)
- Internal failure of the Digital Audio Control Module D (hardware or corrupted firmware)
- Software/calibration incompatibility between the receiving module and the Audio D Module after an update or replacement
- Excessive electromagnetic interference (EMI) on the data bus
- Fault in the receiving module (Gateway/BCM) that misinterprets valid data
3. Symptoms You Will Notice
- Audio system malfunction (no sound, intermittent audio, or distorted output)
- Communication bus errors or warning lights on the dashboard
4. Step-by-Step Diagnosis
Scan all modules for related codes and check communication bus integrity
Inspect wiring and connectors at the Digital Audio D Module for damage, corrosion, or loose pins
Verify power and ground supplies to the Audio D Module
Check for software updates or calibration mismatches between modules
Perform a network test to isolate the faulty module (e.g., disconnect Audio D and see if bus errors clear)
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, the vehicle is generally safe to drive, but audio system features may be unavailable. Have the issue diagnosed soon to prevent potential communication bus problems.
How much does it cost to fix?▼
Diagnosis typically costs $100-$200. Repair costs vary: wiring repairs $150-$400, module replacement $400-$1200 including labor and programming.
