Environmental concerns today make emission testing a critical part of the automotive industry. MindTree knows that vehicle diagnostics and emission testing have also become vital maintenance components for automotive OEMs, dealers, and vehicle maintenance companies. With remote diagnostics, OEMs can reduce warranty costs and improve customer relationships in the short term, and ultimately realize savings through design cycle and component quality improvements. Emission testing units are required to identify malfunctions in vehicle components that regulate fuel/air ratios (like EGR valves and oxygen sensors), detect dirty air filters, misfiring spark plugs, vacuum system leaks, or even a poor-fitting fuel cap.

MindTree has the expertise with technologies and standards in the diagnostics area to help you stay abreast of regulations, and adopt new technologies as norms change. We have worked on products like handheld diagnostics tools, emission testing systems, and prognostics solutions. MindTree’s expertise includes:

Technologies and Standards
  • CAN, K-line
  • KW2000
  • J1850 VPW, J1850 PMW
  • J1708 & J1939
  • SJ1455 Qualification Tests
  • ALDL
  • ISO 9141

The following is a sample list of products and solutions that MindTree has worked in the diagnostics and emission testing area:
