Engine TSC1 Throttling and Emissions Messaging Troubleshooting

Our Powercore, PV380, and other display and controller products typically have menu options that allow you to select an engine manufacturer and or engine model number which will automatically set the unit up to control the engines throttle and emissions over J1939 CAN.

If a specific engine manufacturer is not listed or the selection is not working here are some steps to follow.

• Download this reference guide for a list of Source Addresses and TSC1 definitions.
• Select "Other" in the engine manufacture setting
• Obtain a engine manual that details the J1939 Communication Interface
• Find the Source Address (SA) required for the TSC1 Throttle messages
• Note that some engine distributors will change the TSC1 source address to a specific number of their choosing. (example 44 for John Deere engines instead of 43).
• Determine Emissions Control source address, this may or may not be the same as the TSC1 SA.
• Setup the source addressing in the menu of the display or the controller.
• Most of the later products (after 2021) allow you to have  one address for TSC1 throttling and a separate address for emissions. The later is usually listed as just the source address of the device.
• If no menu option exists for split source addressing check for configuration updates.
• Verify Engine ECU has been properly configured for J1939 TSC1 throttle control.
• It may be necessary to turn off throttle pedal or inc/dec throttling in the ECU configuration.
• Verify permissives have been met, minimum temperatures, run time, and RPM are met for entering regen modes. A engine may reject a request for regen if these are not met.
• If there are CAN messages, icons, operator warnings, or other missing then contact your EC representative or technical support to determine a solution. 
• The configurations for most of these products is available on the support site or as part of Powervision allowing you to add the missing features using Powervision Configuration Studio.  
• Obtain a CAN data log to share with EC personnel to help diagnose any issues.
