Find the fault. See the data. Get back to work. Diagnose supported Caterpillar excavators with a compact, rugged scan tool that reads and clears fault codes, explains active issues, and displays live machine data—no laptop required. Caterpillar Excavator Compatible Diagnostic Scan Tool & Fault Code Reader When a warning light, reduced performance, or unexpected operating issue interrupts the job, this handheld diagnostic tool helps you take the first step toward a faster, more informed repair. Connect it to the diagnostic port on your supported Caterpillar excavator to retrieve Diagnostic Trouble Codes (DTCs), look up code meanings, clear repaired faults, and monitor available machine data. Fitment matters: This scan tool is designed only for the Caterpillar excavator models shown in this product's year and model-family selectors. Please choose and confirm your exact machine before ordering from the drop down boxes above. What the scanner can show Current and stored code statusCheck supported active codes (DM1) and logged codes (DM2), then use the code-meaning lookup to help direct your troubleshooting. Live engine readingsView available data such as RPM, coolant temperature, oil pressure, fuel rate, boost pressure, battery voltage, and more. Machine operating informationSee supported values including engine hours, fuel level, machine speed, throttle position, and transmission gear position. Emissions and system readingsOn compatible machines, review available EGR, aftertreatment, turbocharger, and sensor information. Examples of faults it can help you investigate The scanner can support a broad range of standard diagnostic trouble codes. The examples below show the type of issue it can help you investigate; actual code coverage and descriptions depend on your selected machine, ECM, and installed equipment. Engine & performanceExamples include low or high engine oil pressure, coolant-temperature issues, high intake-manifold temperature, torque derate, abnormal engine-speed updates, low fuel-rail pressure, and high turbocharger boost pressure. Electrical & sensor issuesExamples include battery voltage too low or high, a non-responsive throttle-position sensor, high engine-oil temperature, low fuel temperature, and a lost vehicle-speed signal. Emissions & aftertreatment*Examples include EGR calibration, high DPF soot level, aftertreatment-system faults, low aftertreatment inlet temperature, and low DEF pressure where applicable. Communication & position sensorsExamples include CAN communication errors, crankshaft-speed sensor faults, camshaft-position sensor faults, abnormal accelerator-pedal signals, and a requested malfunction-indicator lamp. * Emissions and aftertreatment data is shown only where supported by the machine's ECM and configuration, often it is it's own separate computer unit and thus is not supported. See fault information without guessing. The code screen gives you a clearer starting point by showing active or logged DTC information that your selected machine supports. After the underlying repair is complete, the tool can clear the detected code. Live data while the machine is running Use live data to see the information behind the warning light or performance concern. Depending on your machine's available ECM data, the scanner can help you monitor the engine, electrical system, fuel system, turbocharger, aftertreatment, and key operating conditions in real time. Engine performanceSupported values may include engine speed, coolant temperature, oil pressure, fuel rate, boost pressure, intake-manifold temperature, and throttle position. Electrical & machine statusSupported values may include battery voltage, engine hours, fuel level, machine speed, gear position, and sensor-status information. Read the numbers that matter to the repair. Live readings help you spot abnormal values early, confirm that a repair has worked, and make more informed maintenance decisions. Actual screen layouts and available readings vary by model and machine configuration.
