B1287 Chevrolet Description

The radio provides a remote amplifier mute output circuit to control overall muting of the remote amplifier. The amplifier receives Pulse Width Modulated (PWM) signals on the control circuit at varying duty cycle percentages for controlling muted and unmuted functions of the amplifier. Circuitry internal to the radio monitors the remote amplifier mute circuit for faults and sets the appropriate Diagnostic Trouble Code (DTC) when faults are detected.
