Electronic Control Unit

Electronic Control Unit

The Electronic Control Unit by HJS monitors a filter automatically by measuring the backpressure and temperature of the exhaust gases. Both pieces of information are displayed by the  HJS "ServiceCheck"display module, which means the status of the filter is immediately visible at all times. The Service Unit is included in the scope of  delivery and ensures the filter functions at optimum efficiency.

Benefits

  • Constant monitoring of the exhaust backpressure and temperature
  • Overload detection for the particulate filter
  • Automatic indication that the filter needs to be cleaned
  • Lower maintenance costs

Our ECU (Electronic Control Unit) diagnostics software is required for installing, servicing and troubleshooting with an HJS diesel particulate filter system equipped with an electronic monitoring function (e.g. SMF®-CRT® or SMF®-AR).

ECU diagnostics software

With the aid of a commercially available laptop computer and a diagnostics cable, the diagnostics software can communicate with the HJS ECU of the respective filter system. Data can be read out, commands given and actions executed. The software must be registered with HJS the first time it is started, so that all the functions built into it can used. Registering the program involves entering a password, which your local sales partner will be able to provide you with. Further information can be found in the User's Manual below.

The very latest version of the ECU diagnostics software, which you can install on your PC, the User's Manual and a few notes on compatibility you will find in our Download area.
