369-8874 Machine Software Gp
Selectable Ride Control Activation - There is a new configuration parameter in ET. The new parameter allows dealers to adjust the activation speed for Ride Control to best suit the application. Only the activation speed is adjusted manually. (The de-activation speed is automatically set slightly lower from the activation speed to prevent the solenoid from tripping on and off near the trip point.)
Temporary Pattern Changer - There is now a temporary Pattern Changer configuration parameter. The dealer has 50 hours of free demo use of the dedicated pattern changer (once the configuration is enabled). The SEA (Software Enabled Attachment) must then be purchased to continue use.
Speed Sensor Fault Criteria - The criteria under which the software considers a faulted speed sensor signal has been widened to reduce false codes.
Controls Active Test Removed – Eliminated the interlock which checked to ensure that the joysticks were in neutral before allowing the engine to crank. This redundant check was resulting in good joysticks being replaced due to occasional transients on the joystick position sensors at key on. The parking brake, seat switch, and armbar are still checked before cranking the engine. The joysticks are disabled until the parking brake has been turned off.Adaptable To: The new 369-8874 Machine Software Gp is used on all C-Series machines. Use WinFlash (J1939 enabled) to update the electronic control module. Use CAT ET v2010C to update the electronic control module.
