Sound Signal Circuit between Radio Receiver and Stereo Jack Adapter
DESCRIPTION
The No. 1 stereo jack adapter assembly sends the sound signal from an
external device to the radio and display receiver assembly via this circuit.
The sound signal that has been sent is amplified by the radio and display
receiver ...
VC Output Circuit
DESCRIPTION
The ECM constantly generates 5 V of power from battery voltage supplied to the
+B (BATT) terminal to operate the microprocessor. The ECM also provides this power
to the sensors through the VC output circuit.
When the VC circuit is short-cir ...
