Code B1095:04 Description
The audio amplifier is a participant on the MOST network. The audio amplifier receives audio input and control information from the MOST bus.
Each of the audio output channel circuits (+) and (−), at the audio amplifier have a DC bias voltage that is approximately one-half of the battery voltage. When using a DMM, each of the audio output channel circuits will measure approximately 6.5V DC. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound.
The Diagnostic Trouble Code (DTC) will be set when an open is detected on the specified (+) (positive) or (−) (negative) signal circuit.
What are the Possible Causes of the DTC B1095:04?
- Faulty Audio Amplifier
- Faulty Left Front Instrument Panel Speaker
- Left Front Instrument Panel Speaker harness is open or shorted
