Description
Diagnose complex automotive faults by analyzing data and testing systems; perform programming and calibrations, develop repair plans, and verify repairs through targeted testing and road tests.
- • Test drive vehicles to reproduce concerns and gather diagnostic data.
- • Connect scan tools to retrieve DTCs, freeze-frame, and live data.
- • Use oscilloscopes, multimeters, and test lights to analyze electrical circuits.
- • Perform CAN/LIN network diagnostics and identify communication faults.
- • Conduct pinpoint tests following OEM flowcharts and service information.
- • Research technical service bulletins, wiring diagrams, and repair histories.
- • Perform compression, leak-down, and cylinder balance tests.
- • Measure fuel pressure, volume, and injector performance.
- • Diagnose ignition and misfire issues using waveform and data analysis.
- • Perform EVAP and emissions system diagnostics with smoke machines and monitors.
- • Evaluate charging and starting systems, including parasitic draw testing.
- • Inspect harnesses, connectors, grounds, and sensors for damage or corrosion.
- • Test and verify operation of engine management sensors and actuators.
- • Diagnose ABS, traction, and stability control faults.
- • Evaluate HVAC control and blend door operation using scan data and tests.
- • Diagnose infotainment, body control, and comfort system concerns.
- • Perform module programming, coding, and software updates as required.
- • Calibrate ADAS components and steering angle sensors after service.
- • Initialize and relearn systems such as TPMS, throttle, and crankshaft position.
- • Provide clear repair plans and parts/labor estimates based on findings.
- • Communicate diagnostic results and recommendations to service advisors and customers.
- • Document test procedures, measurements, and root-cause conclusions on work orders.
- • Verify completed repairs meet OEM specifications through targeted retesting.
- • Support technicians during complex diagnostics and provide guidance.
- • Maintain and update diagnostic equipment, software, and subscriptions.
- • Follow safety procedures for high-voltage, fuel, and airbag systems.
- • Diagnose drivability, performance, and NVH concerns.
- • Conduct quality-control inspections prior to vehicle delivery.
- • Plan work sequences to maximize accuracy and efficiency.
- • Keep work area and tools clean and organized.
