Engine monitoring
During remote start the system will need to know what the
engine is doing and how fast it is idling in order to determine if
the car is running. The module does this by monitoring the
voltage of the vehicle’s electrical system. When the vehicle is not
running the electrical system should read approximately 12 volts
and will increase up to 14.40 volts when running. The remote
start system monitors the increase to prevent the starter from
cranking when the vehicle is already running.
If the idle is too slow or too high, the system will shut down the
engine to prevent damage. If the starter does not crank long
note: Additional parts may be required to interface with
certain door lock types.
