Circuit breaker #5 to remote control switch (1)
Circuit breaker #11 to the key start switch
Circuit breaker #14 to Engine ECM (5)
Circuit breaker #9 to Power Train ECM (4)With remote control switch (1) in the ON position, a radio signal is sent by the transmitter to the receiver. The receiver sends a signal to remote control logic unit (2). Engine stop relay 16 (3) will energize and supply 24 V power to Engine ECM (5). The engine will run.When the transmitter sends a stop engine signal to the receiver, the receiver stops power to engine stop relay 16 (3). 24 V power is no longer supplied to Engine ECM (5). The engine will shut down.Reference: For more information on the remote control system, refer to Systems Operation, Testing, and Adjusting, "Remote Control System".
