The NEXIQ Technologies eTechnician Software Combo includes two PC-based diagnostic software applications, eTechnician Heavy Duty Standard (HDS) and eTechnician Light and Medium Truck (LMT). The eTechnician HDS application provides technicians with the ability to perform heavy duty diagnostics, using both J1708 and J1939 communication protocols on a PC platform. It includes coverage for heavy duty engines, transmissions, brakes, trailers, body controllers, instrument clusters and emissions. The eTechnician LMT application provides OEM proprietary diagnostic capabilities for engines, transmissions and brakes on a wide range of light and medium duty trucks. It features hundreds of diagnostic tests, and the application includes generic OBD-II. Both pieces of software allow techs to switch between each of the elements of the system, saving both repair and vehicle downtime, according to the company.
