  • Starter circuit analysis – Voltage drop testing, solenoid operation, motor draw

  • CAN bus network scan – Communication faults, module dropouts, signal integrity



Wiring & Circuit Diagnostics:


  • Multimeter & oscilloscope testing – Voltage, current, resistance, waveforms

  • Parasitic drain measurement – Current draw testing to 0.01mA accuracy

  • Wiring continuity & resistance – Harness integrity, earth point testing

  • Fuse/relay function testing – Load and signal verification



Electronic Control Systems:


  • ECU/module communication – Fault code reading, live data, adaptations

  • Sensor signal analysis – Voltage, resistance, frequency testing

  • Immobiliser & key coding – Transponder programming, key learning
