In the rapidly evolving automotive landscape, integrating cutting-edge off-board diagnostics tools has triggered a paradigm shift in diesel engine applications. Simultaneously, engineers are compelled to transform conventional mechanical engines into advanced common rail direct injection (CRDi) systems amidst India’s changing pollution norms for industries. Aligned with Bharat Stage Emission Standards, non-road vehicles face stringent emission limits, necessitating complex electronic control predominantly managed by the engine control unit (ECU). Government mandates require the ECU to detect NOx control malfunctions and emission-affecting faults, storing data for off-board analysis. A tool that can read engine data and monitor engine health is required to deal with this situation. Network protocols such as CAN enable remote communication with specialized ECUs.
