Core Responsibilities

Primary Functions

  • Perform comprehensive diagnostic testing on vehicle ignition systems using advanced scan tools, multimeters, and oscilloscopes to accurately pinpoint root causes of engine misfires, no-start conditions, and performance degradation.
  • Expertly interpret complex wiring diagrams and technical service bulletins (TSBs) to trace and repair faults within ignition circuits, including wiring harnesses, connectors, and ground points.
  • Diagnose and replace faulty ignition components such as ignition coils, coil packs, coil-on-plug units, and ignition control modules (ICMs), ensuring compatibility and proper installation procedures.
  • Conduct thorough inspection, testing, and replacement of spark plugs and high-tension leads, meticulously setting spark plug gaps to manufacturer specifications for optimal combustion.
  • Service and repair distributor-based ignition systems, including the replacement of distributor caps, rotors, points, and condensers, as well as setting ignition timing using a timing light.
  • Diagnose and address issues related to crankshaft and camshaft position sensors, understanding their critical role in ignition timing and sequence for modern engine management systems.
  • Utilize OBD-II and other diagnostic software to read, interpret, and clear diagnostic trouble codes (DTCs) related to the ignition system and engine performance.
  • Perform flash programming and software updates on Engine Control Units (ECUs) and Powertrain Control Modules (PCMs) to resolve ignition-related software glitches or to install performance upgrades.
  • Analyze engine performance data, including fuel trim, misfire counts, and sensor data, to identify underlying issues that may manifest as ignition system symptoms.
  • Test and verify the functionality of the primary and secondary ignition circuits, measuring voltage, resistance, and amperage to ensure all components are operating within specified parameters.
  • Address drivability concerns such as hesitation, stumbling, and lack of power by systematically ruling out or confirming the ignition system as the cause.
  • Inspect and repair the charging and starting systems, including batteries, alternators, and starter motors, as they are intrinsically linked to the health of the ignition system.
  • Maintain a detailed and accurate record of all diagnostic steps, repairs performed, and parts replaced for each vehicle, ensuring clear communication for service advisors and customers.
  • Collaborate with other technicians and service advisors to discuss complex diagnostic challenges and develop effective repair strategies.
  • Stay current with emerging automotive technologies, including hybrid and electric vehicle high-voltage ignition systems, through continuous training and professional development.
  • Educate customers or service advisors on the nature of the ignition system failure and the importance of the recommended repairs for vehicle safety and longevity.
  • Manage workshop tools and diagnostic equipment, ensuring they are properly maintained, calibrated, and stored to guarantee accuracy and safety.
  • Perform comprehensive vehicle inspections to identify potential future issues, providing preventative maintenance recommendations to customers.
  • Test-drive vehicles before and after repairs to verify that the customer's concern has been fully resolved and the vehicle is operating correctly.
  • Adhere strictly to all workplace safety protocols and environmental regulations, especially when handling electrical components and hazardous materials.
  • Investigate and resolve intermittent electrical faults within the ignition system, which requires patience, meticulous testing, and a deep understanding of vehicle electronics.
  • Evaluate and repair wiring harness damage caused by heat, friction, or environmental factors to prevent intermittent shorts or open circuits in the ignition system.

Secondary Functions

  • Support ad-hoc data requests and exploratory analysis of historical repair data to identify common failure trends.
  • Contribute to the organization's knowledge base by documenting unique diagnostic procedures and repair solutions.
  • Collaborate with the parts department to ensure accurate inventory levels for common ignition system components.
  • Participate in team meetings and training sessions to share knowledge and improve overall shop performance.
