DESCRIPTION
This circuit sends a signal to the stereo component amplifier assembly to mute noise. Due to this, the noise produced by changing the sound source ceases.
If there is an open in the circuit, noise can be heard from the speakers when changing the sound source.
If there is a short in the circuit, even though the stereo component amplifier assembly is functioning normally, no sound or only an extremely faint sound can be heard.

Speed Signal Circuit
DESCRIPTION
The combination meter assembly receives the vehicle speed signal from this circuit.
The wheel speed sensors produce an output that varies according to the vehicle speed.
The wheel speed sensor output is received by the skid control ECU which u ...
