Automotive Servicing NC I study plan

Explain in plain language the five steps of the hazard-identification-to-control cycle (identify, assess, control, record, review) and apply them to three workshop scenarios you write yourself

Demonstrate the correct sequence for donning and doffing PPE (coveralls, safety glasses, gloves, hearing protection, respirator fit check) and list the inspection criteria for each item before use

Classify ten hand tools from a written list into measuring, cutting, holding, striking, and turning categories, and state the inspection point that most often fails for each

Read a metric micrometer, a vernier caliper, and a dial indicator from written readings (no images) and convert each result to the nearest 0.01 mm

Describe the lockout/tagout and housekeeping steps required before and after using a bench grinder or hydraulic press

Describe the correct use, care, and calibration check interval for torque wrenches, feeler gauges, and tyre pressure gauges, and explain the consequence of using a torque wrench as a breaker bar

Outline a 15-point pre-start vehicle walk-around inspection in the order a technician would perform it, stating what is being checked and the reject criterion at each point

Explain how to read tyre size, load index, speed rating, and DOT date code from a written tyre sidewall string, and state when a tyre must be removed from service

List the fluid levels and condition checks in a preventive maintenance service (engine oil, coolant, brake fluid, power steering, transmission, washer, battery electrolyte where applicable) with the specification source for each

Build a written preventive maintenance schedule for 5,000 km, 20,000 km, and 40,000 km intervals and justify each added item

Explain the four-stroke cycle in both spark-ignition and compression-ignition form, naming valve positions, piston direction, and what each stroke accomplishes

Identify the function of the major engine support systems (lubrication, cooling, fuel, intake and exhaust, ignition or injection) and state one common failure symptom for each

Describe the procedure for checking and adjusting valve clearance, including why the engine must be cold or hot per specification and how the firing order is used

Explain how to perform a compression test and a cylinder leakage test, and interpret three written result sets to decide whether the fault is rings, valves, or head gasket

Trace the flow of coolant through the engine, radiator, thermostat, and water pump, and diagnose overheating from a written symptom list

Describe the purpose and adjustment of the timing belt or chain, and list the alignment marks and tension checks a technician verifies before and after replacement

Explain the components and function of a charging system (alternator, regulator, battery) and a starting system (battery, starter motor, solenoid, ignition switch), and state the normal voltage readings expected at rest, cranking, and charging

Apply Ohm's law to ten written circuit problems to find voltage, current, or resistance, and explain how a voltage drop test locates a high-resistance connection

Describe how to use a digital multimeter to measure voltage, resistance, and current, including lead placement, range selection, and the safety rule for each mode

Explain the function of fuses, relays, and grounds in a vehicle circuit, and outline a systematic diagnostic sequence for a non-working accessory given only a written symptom description

Read a written wiring description and identify the circuit protection, control device, load, and ground path, then state the first three test points in order

Explain the construction and operation of lead-acid and maintenance-free batteries, including specific gravity, open-circuit voltage, load testing, and safe charging practice

Describe the hydraulic brake system from pedal to wheel cylinder or caliper, and explain how air in the system, a leaking seal, or a faulty master cylinder each produces a different pedal symptom

Outline the procedure for brake pad and disc inspection and replacement, including measurement of pad thickness and disc runout against a written specification

Explain the purpose and adjustment of wheel alignment angles (camber, caster, toe) and describe how each misalignment shows up as a written tyre wear pattern

Describe the components of a MacPherson strut and a double-wishbone suspension, and state the inspection points and rejection criteria for springs, shock absorbers, and bushings

Explain the operation of a recirculating-ball and a rack-and-pinion steering gear, and describe how to check for play, binding, and fluid leaks

Describe the construction and function of a clutch (pressure plate, friction disc, release bearing, flywheel) and explain the symptoms of a slipping versus a dragging clutch

Explain the layout and function of manual transmission, driveshaft, differential, and final drive, including the purpose of the differential when turning

Outline the checks for automatic transmission fluid level and condition, and describe how a written road-test symptom (slipping, harsh shift, delayed engagement) narrows the fault area

Rehearse the written sequence for responding to a workshop emergency (fire, chemical spill, injury, electrical shock) and state the location and purpose of each control in a typical shop

Explain the safe handling, storage, and disposal of used oil, coolant, brake fluid, and batteries under common shop practice, and describe the spill response for each

Solve fifteen timed measurement and specification problems drawn from all domains, showing unit conversions and tolerance decisions

Write a one-page job card for a full preventive maintenance service that lists every check, tool, and specification needed, in the order the work would be done

Explain how to verify that a repaired vehicle is safe to release, including torque re-checks, fluid leak checks, and a functional road-test checklist

Complete two full-length timed practice sets covering all seven domains and review every wrong answer to the underlying principle, not just the correct option

Recite from memory the key specifications and inspection criteria you assembled across weeks 1 to 7, and flag any you cannot state confidently for further review

Diagnose five written fault scenarios that each cross at least two domains (for example an electrical fault causing an engine symptom) and justify your diagnostic order

Review the domains with the lowest practice scores and rewrite your own summary sheet for each weak area

Confirm exam-day logistics: identification requirements, allowed tools, timing, and the venue rules you must follow
