Description Of Change: New software (implement, power train, and monitor software) is now used on certain M series and M series 2 Motor Graders. The new software has improvements for the implement Electronic Control Module (ECM), transmission/chassis ECM, and messenger ECM.

Improvements for Implement ECM on All M Series and M Series 2 Motor Graders

The following improvements are effective for the implement ECM on all M series and M series 2 indicated Motor Graders:

• Updated to enable cross slope without a key cycle after enabling the cross slope feature.

• Added 1 second debounce to Advanced Control Joystick Float command.

• Added Cat^® Grade Control Increment / Decrement switch function. Pressing and holding the switch will change the desired cross slope percentage to the nearest whole number.

• Updated to prevent activation of cross slope diagnostics if cross slope was disabled.

Improvement for Transmission/Chassis ECM on All M Series Motor Graders

The following improvement is effective for the transmission/chassis ECM on all M series Motor Graders unless otherwise indicated:

• Added support for the event codes E1704 (High Transmission Clutch Accumulated Thermal Energy) and E1736 (High Service Brake Accumulated Thermal Energy).

Improvements for Transmission/Chassis ECM on All M Series 2 Motor Graders

The following improvements are effective for the transmission/chassis ECM on all M series 2 Motor Graders unless otherwise indicated:

• Improved brake charge function.

• Added support for the event codes E1704 (High Transmission Clutch Accumulated Thermal Energy) and E1736 (High Service Brake Accumulated Thermal Energy).

Improvements for M Series Messenger ECM for Language Groups

The following improvements are effective for the M series messenger ECM for language groups:

• Added pop-up notification that notifies the operator when the trial installation of the Auto Articulation expires. Updated to give the operator a "Trial Expired" message when the Auto Articulation switch is selected.

• Added a "Shipping Mode" within the implement sub group that is under the "Settings" option in the display.

• Added support for the event codes E1704 (High Transmission Clutch Accumulated Thermal Energy) and E1736 (High Service Brake Accumulated Thermal Energy).

• Improved calibration diagnostics support for the Grade Control system, specifically for diagnostic code 3423-13 (Grade Control System - Out of Calibration).

Adaptable To: The following parts are adaptable to the machines within the listed serial numbers, and are effective with all machines after the listed serial numbers.

The new and former software part numbers are listed in Table 1.
