Fitment is essential: This scanner is designed only for the LS Tractor year-and-model options shown in this product's selector. Choose and confirm your exact model before ordering. What systems can it help you investigate? Your available coverage depends on the LS model selected and the information its ECU makes available. This tool helps you identify an electronically reported problem and choose the next diagnostic check; it does not replace proper mechanical inspection. System area Diagnostic information available where supported Engine & check-engine faults Read engine DTCs, view definitions and check supported engine live data to help narrow the cause of an electronically reported issue. TransmissionWhere supported by the selected model Access transmission-related code and live-data information when the tractor's ECU exposes it, including gear-position information on supported models. Fuel, air & emissions systemsWhere fitted and supported Review available fault information for fuel, intake/turbo, oxygen-sensor and after-treatment systems as reported by the ECU. Electrical, sensor & other ECU-managed systemsWhere supported Use reported codes and available data to investigate battery-voltage, sensor, communication, suspension and other electronically controlled system concerns. More than a code reader: see supported live data A code tells you where to start. Live data can help you decide what to inspect next. Depending on the model and information available from its ECU, the scanner can display supported values such as engine RPM, coolant temperature, oil pressure, fuel rate or pressure, intake/turbo values, throttle position, battery voltage, engine hours, fuel level and transmission gear position. Current & stored fault informationReview electronically reported faults that are active now or recorded in the tractor's available diagnostic information. Freeze-frame & monitor statusUse supported freeze-frame data, monitor/I/M readiness and battery-power information as part of a methodical diagnosis. Vehicle informationAccess supported identification details, including VIN, CIN and CVN. Simple, stand-alone operationA palm-sized tool with a backlit display, one-plug operation and internet software-upgrade capability. How DIY diagnosis works 1 Connect the supplied adapter with the diagnostic scanner to your tractor. Select the diagnostic protocol. 2 Read the DTC, definition and supported data. Use the result to guide your inspection or to give a technician more useful information. 3 Repair the underlying cause before clearing codes. Follow the tool's procedure only after the condition that triggered the fault has been corrected.
