VC Output Circuit
DESCRIPTION
The ECM constantly uses 5 V from the battery voltages 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-circuited, the microprocessor in the ECM and
sens ...
