The VCM is responsible of the following electrical
functions:
Power Distribution
A power supply cut-off relay isolates the battery
from the electrical system to prevent battery drain.
When the safety lanyard is installed, the relay then
supplies current to the VCM.
The relay is located inside VCM.
The VCM distributes power from the battery to the
following electrical components:
– accessories
– fuel pump
– RAVE solenoid
– Ignition coil
– starter solenoid
– injectors
– ECM
Electrical components are protected by fuses in-
