Caterpillar Monitoring SystemAlert indicator (1) indicates a failure of the primary steering. When alert indicator (2) flashes, the secondary steering system is active. When the alert indicators come on and the action alarm sounds, steer the machine immediately to a convenient location and stop the machine. Stop the engine and investigate the cause of the failure. Do not operate the machine until the cause of the failure has been corrected.The Caterpillar Monitoring System will perform a self test of the secondary steering during engine start-up. Alert indicator (2) will come on for three seconds in order to verify the pressurization of the secondary steering system. The action alarm will sound until the end of the self test or until the engine is started.
Do not use the secondary steering as a limp home mode procedure.Continuing to operate the machine by using the secondary steering may result in damage to the secondary steering system.
