<p>The security system for a road vehicle has a seat switch [S3] that is operated when a driver leaves the vehicle. This interrupts a code pad [T] and a relay [R2] operates to isolate the ignition, starter motor and fuel pump supplies [Z,P,A]. An alarm is also triggered. The system may only be reactivated by entering the correct code into the pad.</p> |
