The software for the machine's three electronic control modules have been improved. Following is a summary of the improvements made with each version.
Electronic Monitoring Center (EMC) Software
Changes Made in EMC Version 06.30
1. Fuel Tank - The software has been changed to correctly measure and display the fuel level for the two tank sizes offered for the Challenger 35. EMC version 06.30 or later must be used in conjunction with ETC version 05.13 or later. See Chart A for the values needed to select the fuel tank size with feature 12 in Mode 12.
2. MODE 1 - In MODE 1, the most significant digit scroll was corrected to include zero (0). When entering an implement width for the first time, all digits including the far left (or most significant) digit are zeros (000.0). In earlier version software, if you changed the most significant digit, by use of the digit select key, to some number other than zero, you could not scroll back to zero (0) without pressing the start/stop key for three seconds and re-zero all digits. The new software provides zero (0) as an option for the most significant digit.
3. MODE 3 - "P" code P105 (PTO Stopped) has been eliminated from the diagnostics.
4. MODE 5 - "P" codes P150 (FWD Status), P151 (Diff Lock Status), and P145 (Slip Limit Status) have been eliminated from Right Hand Controls (RHC) output diagnostics.
5. MODE 7 - "P" codes P363 [Diverter (Flip-Flop) Valve] and P364 (Air Inlet Heater Output Control) have been added. A timer has been added to allow output to remain on for 15 seconds maximum. Operator can turn OFF prior to 15 seconds time-out.
6. MODE 12 - All non-Caterpillar configuration parameters have been eliminated. See Chart B for the remaining parameters.
If the Chassis Control Module (CCM) is replaced, a F205 fault code will be generated unless all of the configuration parameters in the CCM match the default values. When in MODE 12, the F205 fault code is displayed on a parameter by parameter basis.
Changes Made in EMC Version 06.37
1. Drive Wheel Radius Entry - A possible error when entering EMC MODE 1 has been corrected. If the Setup/Select Key was depressed for more than six seconds, the drive wheel radius defaulted to 610 mm (24 in) and the Machine Performance Monitor display area locked up. This occurred on the first entry after key ON only. Automatic calibration was also not entering the correct value under certain conditions. The new software requires that the operator enter into the Drive Wheel Radius Size display before calibration can be carried out.
2. Transmission Oil Temperature Bar Graph Display - The bar graph mapping was revised so that the yellow bar was set to 104°C (220°F) and the red bar was set to 108°C (226°F).
3. Engine Hour Display - The leading "1" was not displayed due to a software error in EMC version 06.28. The stored value of the engine hours is not affected. Only the display value was in error.
Right Hand Controls (RHC) Software
Changes Made in RHC Version 03.07
1. Fault Code 099 - Electrical noise or interference affecting the three-point hitch potentiometers. Electrical noise produced by the programmable upshift/downshift switch that created a F099 fault code is now ignored by the RHC.
2. MODE 3 - "P" code P105 (PTO Stopped) from the diagnostics.
Chassis Control Module (CCM) Software
NOTE: The Electronic Transmission Control (ETC) and depending on machine configuration, the Electronic Draft Control (EDC) are contained in the CCM.
Changes Made in ETC Version 05.13
1. Fuel Tank - The software has been changed to correctly measure and display the fuel level for the two tank sizes offered for the Challenger 35. EMC version 06.30 or later must be used in conjunction with ETC version 05.13 or later. See Chart C for the values needed to select the fuel tank size with feature 12 in Mode 12.
Changes Made in ETC Version 05.19
1. Master Clutch Engagement - Transmission master clutch engagement is now limited to F1 engagement only on initial movement. The control will not allow engagement of F2 (8 and 9 high range). F1 is used by default.
2. Differential Steering Logic - The software has been corrected so that the differential steering logic is correct when the parking brake is set during shuttling.
3. Drive Wheel Radius Automatic Calibration - The drive wheel automatic calibration feature has been changed. Previously the feature could be too sensitive, causing unrealistic radius values. The system now recalibrates every 12 minutes. Formerly recalibration occurred 4 times a minute. No automatic calibration occurs until speed is greater than 16 km/h (10 mph) for 20 continuous seconds.
