(2) Power Train ECM With the key start switch in the ON position, 24 V power is supplied via circuit breaker #9 to Power Train ECM (2).Ride control switch (1) is a three position switch with an AUTOMATIC position, SERVICE position, and OFF position. When ride control switch (1) is moved to the AUTOMATIC position, a ground circuit is supplied to Power Train ECM (2). The ride control system will operate when the ground speed exceeds 5 km/h (3.0 mph). The ride control system will automatically turn off if the ground speed is less than 5 km/h (3.0 mph).Note: The ride control system ground activation speed is factory set and can be adjusted using Caterpillar Electronic Technician (ET).

(6) Ride control solenoid Ride control indicator (4) will be on when the ride control system is operating. Transmission speed sensor (5) sends a signal to Power Train ECM (2). Power Train ECM (2) monitors the ground speed of the machine. When the required ground speed has been reached by the machine, the ride control system will activate. 24 V power is supplied from Power Train ECM (2) to indicator lamp panel (3). Indicator lamp panel (3) supplies 24 V power to ride control solenoid (6) to activate the system.When ride control switch (1) is held in the SERVICE position, the ride control system will be activated regardless of ground speed. Ride control indicator (4) will illuminate and ride control solenoid (6) will be activated. Ride control switch (1) will return to the OFF position when released.
