Block diagram for the interlock ECMThe interlock system is standard equipment. The interlock system consists of switches, an ECM, indicators, and actuators. The ECM gathers information from the switches. The information is processed by the software. The ECM will then activate the relays and solenoids. The Interlock ECM utilizes the following components for the input signals:
Switch (start)
Switch (armrest)
Switch (seat)
Switch (parking brake)
Switch (hydraulic lockout)
Switch (door)The interlock ECM controls the following components:
Solenoid valve (hydrostatic pilot)
Solenoid valve (work tool pilot)
Solenoid valve (parking brake)
Coil (work tool detent)
Relay (start)
Relay (fuel shutoff)
Indicator (parking brake)
Indicator (armrest)Specific functions of the interlock system are shown below:
Engine start interlock
Hydrostatic system
Parking brake interlock
