Position: Senior Commercial Vehicle Diagnostic & Electrical Specialist / Technical Team Leader

Work Location: 8 Penjuru Place, #01-40, Singapore 608780

Monthly Salary: SGD 3,500-6,900, depending on technical expertise, diagnostic capability and relevant experience.

Experience: Minimum 5 years of hands-on commercial vehicle diagnostic, repair and troubleshooting experience. Experience in Singapore or Malaysia commercial vehicle workshops is strongly preferred.

1. POSITION OVERVIEW

Tiger Path Pte. Ltd. is seeking an experienced, highly skilled Commercial Vehicle Diagnostic & Electrical Specialist to lead complex troubleshooting and technical repair activities in our workshop.

The candidate must be capable of independently diagnosing, investigating and resolving mechanical, electrical, electronic and engine-management-related faults on prime movers, heavy-duty trucks, commercial vehicles, trailers and diesel-powered vehicles.

The specialist must demonstrate advanced proficiency with Jaltest Commercial Vehicle (CV) Diagnostic Software, diagnostic interface hardware, communication cables, wiring diagrams, multimeters, oscilloscopes and other professional diagnostic equipment .

The successful candidate will act as the workshop's principal diagnostic troubleshooter, provide technical guidance to mechanics and technicians, and support the Workshop Manager in resolving difficult vehicle faults efficiently.

2. MAIN JOB RESPONSIBILITIES

• A. Advanced Vehicle Diagnostics and Troubleshooting
  • Conduct full-system electronic diagnostics using Jaltest and compatible OEM diagnostic systems.
  • Independently identify and resolve complex electrical, electronic, mechanical and engine-management faults.
  • Retrieve, interpret and analyse fault codes, freeze-frame information, live sensor data and diagnostic histories.
  • Troubleshoot recurring, intermittent and multiple simultaneous fault codes.
  • Investigate faults that other mechanics are unable to resolve.
  • Perform systematic root-cause analysis instead of relying on trial-and-error parts replacement.
  • Investigate breakdowns, engine derating, no-start conditions, intermittent shutdowns and communication faults.
  • Determine whether faults originate from mechanical components, wiring harnesses, sensors, actuators, ECUs, software or vehicle communication systems.
  • Prepare clear diagnostic findings and corrective-action recommendations.
• B. Diesel Engine and Fuel Injection Systems
  • Diagnose electronic diesel injection systems, common-rail fuel injection, electronic unit injectors and electronic unit pumps.
  • Troubleshoot injector electrical faults, injector coding issues, fuel pressure faults and fuel delivery problems.
  • Investigate fuel rail pressure, pressure regulator, metering valve and associated sensor faults.
  • Diagnose engine misfiring, unstable idle, excessive smoke, power loss and difficult starting.
  • Troubleshoot turbocharger controls, electronic wastegates, variable-geometry turbocharger actuators, boost pressure and air-management systems.
  • Diagnose coolant temperature, oil pressure, crankshaft position, camshaft position, airflow and exhaust pressure sensor faults.
  • Conduct injector balance and cylinder contribution tests where supported.
  • Carry out approved injector coding, adaptations, calibrations and engine-system resets.
  • Identify mechanical faults that may produce electronic fault codes.
• C. Euro 4, Euro 5 and Euro 6 Emission Systems
  • Diagnose diesel emission-control systems fitted to Euro 4, Euro 5 and Euro 6 vehicles.
  • Investigate SCR (Selective Catalytic Reduction) systems, AdBlue/DEF dosing systems, NOx sensors and related control faults.
  • Troubleshoot EGR valves, EGR coolers, DPF systems and exhaust pressure sensors.
  • Identify causes of excessive soot loading, unsuccessful DPF regeneration and emission-related engine derating.
  • Diagnose AdBlue dosing pumps, injectors, heaters, tank sensors and control circuits.
  • Perform manufacturer-approved DPF regeneration and system adaptations where appropriate.
  • Diagnose repeated emission-related warning lights and unresolved fault codes.
  • Restore the emission-control system to its correct operating condition without bypassing or disabling safety or emission equipment.
• D. Electrical, Electronics and ECU Troubleshooting
  • Read and interpret electrical wiring diagrams and electronic circuit schematics.
  • Diagnose 12V and 24V automotive electrical systems.
  • Troubleshoot open circuits, short circuits, poor grounding, high-resistance connections and voltage drops.
  • Inspect and diagnose damaged wiring harnesses, connectors, relays, fuses, control modules and power distribution circuits.
  • Investigate CAN Bus, J1939 and other supported vehicle communication network faults.
  • Troubleshoot ECU/ECM communication issues and module power-supply problems.
  • Diagnose starting, charging, alternator, starter-motor an
