What Does U0563 Mean?
The receiving module detects invalid or corrupted data being transmitted from Audio Amplifier B over the vehicle communication network. This prevents proper audio system operation and integration with other vehicle systems.
Common Causes
40%
Internal failure of audio amplifier B module causing data corruption
25%
Damaged wiring or poor connections between amplifier and communication bus
20%
Power supply issues to amplifier causing erratic operation and data transmission
10%
Software version mismatch or corrupted firmware in amplifier module
5%
Electromagnetic interference from aftermarket equipment affecting amplifier output
Diagnostic Steps
1
Step 1: Verify audio amplifier B module has proper power and ground using multimeter at module connector
2
Step 2: Check for Technical Service Bulletins regarding audio amplifier software updates or known communication issues
3
Step 3: Inspect amplifier module connectors for corrosion, water damage, or loose pins
4
Step 4: Monitor network traffic with scan tool to determine if amplifier is transmitting any data or completely silent
5
Step 5: Test amplifier functionality by playing audio through different channels; if amplifier works but code persists, suspect internal communication circuit failure
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
The receiving module detects invalid or corrupted data being transmitted from Audio Amplifier B over the vehicle communication network. This prevents proper audio system operation and integration with other vehicle systems.
The most common cause of U0563 (Invalid Data Received From Audio Amplifier "B") is: Internal failure of audio amplifier B module causing data corruption
Typical repair costs for U0563 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No safety impact. Audio system functionality may be degraded or inoperative, but vehicle operation is not affected.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0563 to identify the root cause.
