MITO Light Auto L4 study plan

Describe the four-stroke cycle and explain the purpose of each stroke, then label intake, compression, power and exhaust events on a stripped engine.

Compare petrol and diesel combustion strategies, including ignition method, compression ratio and fuel delivery, and state one diagnostic symptom unique to each.

Explain the function of the major engine support systems - lubrication, cooling, intake and exhaust - and identify the consequence of failure in each.

Identify the main drivetrain layouts (FWD, RWD, AWD/4WD) and trace power flow from engine to road wheel, naming each component in order.

Diagnose three common engine-running faults (misfire, overheating, excessive oil consumption) by listing the tests you would run and the result that confirms each cause.

Describe how to perform a compression test and a cylinder leak-down test, including preparation, safety steps and how to interpret the readings.

Apply Ohm's law and series/parallel circuit rules to calculate expected voltage, current and resistance in simple automotive circuits.

Demonstrate correct use of a digital multimeter for voltage, resistance and continuity measurement, and state when each mode is unsafe or invalid.

Explain the operation of the battery, starter motor and charging system, and describe the test sequence used to isolate a no-crank or no-charge fault.

Read a vehicle wiring diagram to trace a lighting or accessory circuit from fuse to earth, and identify connector, relay and ground locations.

Perform a voltage-drop test procedure on a high-current circuit and explain why it is more reliable than a resistance reading.

Describe the role of sensors and actuators and how ECU inputs are converted into outputs, using two named sensors as examples.

Interpret body and network communication basics, including what a CAN bus does and how a shorted or open data line shows up as a symptom.

Identify steering system components (rack and pinion, steering column, power assistance) and explain how each wear point produces a specific complaint.

Define the main wheel alignment angles - camber, caster, toe and thrust angle - and predict the tyre wear pattern each incorrect angle causes.

Describe suspension types (MacPherson strut, double wishbone, live axle) and match each to a vehicle class and handling characteristic.

Explain hydraulic braking principles, including Pascal's law, brake fluid properties, bleeding sequence and the effect of aerated or contaminated fluid.

Compare disc and drum brake construction and describe the inspection points and wear limits for pads, rotors, shoes and drums.

Describe the operation of ABS and traction control, including the function and failure symptoms of wheel speed sensors.

Diagnose three common steering or suspension complaints (pull, vibration, clunk) by linking each to at least two possible causes and the test that separates them.

Diagnose a brake fault end to end: gather the customer description, verify the symptom, choose the test, confirm the root cause and specify the repair.

Select and use measuring tools correctly - vernier caliper, micrometer, dial indicator, feeler gauge - and record readings to the correct precision.

Apply correct torque procedures, including fastener grade, thread condition, torque-to-yield bolts and the reason for a torque wrench calibration check.

Locate and use service information, wiring diagrams and technical bulletins to find a specification rather than relying on memory.

Use a scan tool to read, interpret and clear diagnostic trouble codes, and explain why clearing a code before recording freeze-frame data destroys evidence.

Describe when to use an oscilloscope instead of a multimeter, and interpret a basic injector or ignition waveform.

Identify workplace hazards in an automotive workshop - lifting equipment, jack stands, exhaust gas, fuel vapour, high-voltage and rotating components - and state the control for each.

Explain the safe handling, storage and disposal requirements for workshop fluids, batteries and waste oil under current environmental obligations.

Describe the correct procedure for raising and supporting a vehicle, including load rating, lifting points and the rule against working under a vehicle held only by a jack.

Complete two full-length timed mock exams across all five domains and record the score for each domain separately.

Re-study the two weakest domains, targeting only the sub-topics that produced incorrect answers.

Respond to three written safety scenarios (fire, fuel spill, electric vehicle contact) with the correct immediate actions and reporting steps.

Explain professional and ethical obligations: accurate record keeping, honest customer communication, and knowing when a job exceeds your competence or licence.
