|B15D0 LEXUS code description

This Diagnostic Trouble Code (DTC) is stored when the MOST network cannot be established after the master unit is activated. If a short occurs in a speaker circuit, the sound from the corresponding speaker will be low or almost impossible to hear. If the volume is turned up in this situation, to prevent excessive current flow due to the short circuit, the stereo component amplifier assembly stops operating when its output exceeds a certain level. When the operation of the stereo component amplifier assembly stops, the audio and visual system will not function normally. This is because MOST communication will stop due to the shut down of the amplifier causing an error in the MOST network. The stereo component amplifier assembly will start operating again when the engine switch is turned off and back on (ACC) again. However, the amplifier will stop operating again if its output exceeds a certain level. When the stereo component amplifier assembly stops operating and a malfunction occurs in the audio and visual system due to a short in a speaker circuit, this DTC will be stored.
