Normal Operation
The audio unit enables the digital signal processing (DSP) module through circuit CME27 (YE/VT). The DSP module receives voltage through circuit SBP15 (WH/RD), and ground through circuit GD148 (BK/YE). Audio signals are processed by the DSP module and sent to each of the audio amplifiers, which amplify the audio signals and route them to the speakers.

Possible Causes
- Fuse
- Circuit CME27 (YE/VT) open or short to ground
- Circuit GD148 (BK/YE) open
- Circuit SBP15 (WH/RD) open
- DSP module
- Audio unit
