Secondary Steering (If Equipped)
The optional secondary steering system provides steering control of the machine when the primary steering system has failed. The secondary steering system is intended for emergency use only.Reference: For more information on the secondary steering system, refer to the Service Manual module Systems Operation, "Secondary Steering System" for the machine that is being serviced.Ride Control Function (If Equipped)

Indicator display (2) Ride control ACTIVERide control is an optional function that is enabled by a programmable parameter via the Caterpillar Electronic Technician (ET). Ride control is enabled when the operator places the ride control switch (1) in the ON position or the AUTO position. In the ON position, ride control is activated at all times and the power train ECM continuously energizes the ride control solenoid. This mode should only be used when the machine is being serviced. Never operate the machine with the ride control switch in the ON position. In the AUTO position, ride control is activated when the machine ground speed increases above approximately 6 mph. In the AUTO position, ride control is deactivated when the machine ground speed is below approximately 5.5 mph. The default speed can be changed with the configuration screen of the Caterpillar Electronic Technician (ET). As ride control is activated and deactivated the ride control solenoids are alternately energized and de-energized.The three ride control solenoids for the ride control are outputs of the power train ECM. The ride control solenoids turn the ride control system on and off. When ride control is disabled, the number one ride control solenoid and the number three ride control solenoid are de-energized and the number two ride control solenoid is energized. When ride control is enabled, the number one ride control solenoid and the number three ride control solenoid are energized 1 second after the number two ride control solenoid is de-energized. The delay time can be changed with the ride control equalization pressure time parameter of the Caterpillar Electronic Technician (ET). All of the ride control solenoids have a connector with two contacts. The number one ride control solenoid receives power from the connector contact J2-5 of the power train ECM. The number two ride control solenoid receives power from the connector contact J2-6 of the power train ECM. The number three ride control solenoid receives power from the connector contact J2-3 of the power train ECM. All of the ride control solenoids return power to connector contact J2-4 of the power train ECM.Reference: For more information on the Caterpillar Monitoring System, refer to the Service Manual module Systems Operation, "Monitoring Systems (Power Train Functions)" for the machine that is being serviced.Reference: For more information on the power train electronic control module (ECM), refer to the Service Manual module Systems Operation, "Electronic Control Module (Power Train)" for the machine that is being serviced.Speed Limiter (If Equipped)
The optional speed limiter software allows the operator to limit the maximum ground speed for a machine that is operating on a
