function is a tool that is used as an aid for managers and maintenance personnel. This function allows tracking of the history of the machine. The ECM stores the data from significant events. The following counters and events are defined in the service tool (ET) for the Articulated Truck. Events and CountersThe counters that are recorded are listed below."Lockup Clutch Count" - This counter records each engagement of the transmission lockup clutch. "Cross Axle Lock Kickout Occurrences" - This counter records each engagement of the cross axle lock kickout. A cross axle lock kickout occurs when the ECM causes the cross axle to unlock when the operator switch has requested that the cross axle is locked. The conditions that could cause the cross axle lock kickout to engage are listed: machine overspeed and a short to battery on the interaxle differential lock solenoids."Differential Lock Switch Cycles" - This counter records the number of times that the differential lock switch has cycled from the off position to the on position."Interaxle Differential Lock Solenoid Cycles" - This counter records the number of times that the interaxle differential lock solenoid has cycled from the off position to the on position."Cross Axle Lock Solenoid Cycles" - This counter records the number of times that the cross axle lock solenoid has cycled from the off position to the on position."Top Drive Gear Switch Cycles" - This counter records the number of times that the top drive gear switch has cycled from the off position to the on position."Transmission Hold Override Occurrences" - This counter records the number of times that the activation of the transmission hold switch has caused the transmission to hold the current gear instead of shifting to a different gear."Transmission Hold Switch Cycles" - This counter records the number of times that the hold switch has cycled from the OFF to ON or ON to OFF."Service Brake Pressure Switch Cycles" - This counter records the number of times that the service brake pressure switch has cycled from the off position to the on position."Retarder Pressure Cycles"725 and 730 only - This counter records the number of times that the retarder pressure has cycled from the off position to the on position."Parking Brake Pressure Switch Cycles" - This counter records the number of times that the parking brake pressure switch has cycled from the off position to the on position."Parking Brake Solenoid Cycles" - This counter records the number of times that the parking brake solenoid has cycled from the off position to the on position."Starter Relay Cycles" - This counter records the number of times that the starter relay has cycled from the off position to the on position."LUC Counter" - This counter records the number of times the Torque Converter Lockup clutch transitions from the off position to the on position.The events that are recorded are listed below."Shift Count Matrix" - This matrix is used to read the number of shifts of each type that the transmission has made
