ENGINE CONTROL UNIT (ECU) SUPPORT
The following paragraphs describe the support provided by the DGC-500 for operation with an engine control
unit (ECU).
Enabling ECU Support
To enable ECU support, the user must access the SYST menu in BESTCOMS and select Enable ECU
Support under the box entitled CANBus/J1939 Interface. After resending the settings, the DGC-500 will ignore
the analog inputs for coolant temperature, oil pressure and engine speed, and it will no longer calculate engine
run-time. Once the DGC-500 establishes communication with an ECU, the engine run-time, coolant level,
coolant temperature, oil pressure, and engine speed will be updated with the ECU values.
