631K and 637K Wheel Tractor-Scraper Systems Electronic Control Module (ECM) - Configure Caterpillar


Electronic Control Module (ECM) - Configure
`

When an ECM is replaced, the ECM must be configured. The software is flashed either at the factory or at the time of installation on the machine. The saved configuration data from the ECM that was replaced will restore the parameters that were configured.

An explanation of the configured parameters for the Transmission/Chassis ECM that will load factory defaults when the software is flashed are listed below:

Transmission Serial Number - The serial number will be listed for the transmission that is installed on the machine.

Autoshift Installation Status - Autoshift is a software enabled function. A factory password is required to install this function. Factory default is "Not Installed".

Transmission Shift Control Parameters - Transmission Shifting patterns can be configured for the Manual Mode and the Autoshift Modes. The parameters that can be configured are: Initial gear in the forward and reverse direction Maximum gear in the forward and reverse direction Maximum Autoshift gear in the forward and reverse direction Minimum Autoshift gear in the forward and reverse direction Refer to Systems Operation, "Features" for more information on the transmission parameters that can be configured.

Machine Speed Limit - This function limits machine maximum travel speed. The factory default is "Disabled". When enabled, this parameter will limit engine driven speed for specific gears. The parameter will not limit speed caused by other factors such as rolling downhill. The configurable range is 3.2 km/h (2.00 mph) to 52 km/h (32.3 mph). Factory default is 52 km/h (32.3 mph).

Machine Speed Correction Factor - The machine travel speed is calculated using the transmission output speed and the tire size. This parameter allows for adjustment for higher accuracy when measured against external speed measuring devices. The configurable adjustment range is minus (-) 8 percent to plus (+) 8 percent of the ECM calculated value. The factory default is 0 percent.

The following oil viscosities are available for selection:

  • TDTO SAE 0W-20

  • TDTO SAE 0W-30

  • TDTO SAE 5W-30

  • TDTO SAE 10W

  • TDTO Arctic

  • TDTO TMS

  • TDTO SAE 30W (Factory Default)

  • TDTO SAE 50W

Air Conditioning System Installation Status - Indicates whether the air conditioning system is enabled. The factory default is "Not Installed".

Battery Cable Shield Monitoring System Installation Status - Indicates that the ECM detects the voltage of the Battery Cable Shield Monitor circuit is above normal.

Cold Engine Parasitic Load Reduction Installation - Requires the transmission bypass solenoid to be installed. This feature helps to heat up the oil faster in cold conditions. Factory default is "Not Installed".
