Non-bussed vehicle amplifier diagnostics

A method for implementing non-bussed amplifier diagnostics for a vehicle, the method comprising:

• transmitting, via an input device in the vehicle, an analog signal indicative of a diagnostic test trigger;
• receiving the analog signal, at a computer processor of an amplifier disposed in the vehicle, the amplifier communicatively coupled to the input device via wiring;
• executing, by the computer processor, a diagnostic test defined by the diagnostic test trigger;
• selecting, by the computer processor, an audio test tone based on results of the diagnostic test and transmitting the audio test tone to speakers communicatively coupled to the amplifier, the audio test tone being one of a plurality of audio test tones stored in a memory unit coupled to the amplifier;
• and
• outputting the audio test tone via the speakers.

A computer program product implementing non-bussed amplifier diagnostics for a vehicle, the computer program product comprising a computer-readable storage medium encoded with instructions, which when executed by a computer cause the computer to implement a method, the method comprising:

• receiving, from an input device, an analog signal indicative of a diagnostic test trigger, the input device communicatively coupled to the computer of an amplifier in the vehicle via wiring;
• executing a diagnostic test defined by the diagnostic test trigger;
• selecting an audio test tone based on results of the diagnostic test and transmitting the audio test tone to speakers communicatively coupled to the amplifier, the audio test tone being one of a plurality of audio test tones stored in a memory unit coupled to the amplifier;
• and
• outputting the audio test tone via the speakers.
