8 weeks · About 7 hours per week
Diagnosis and Rectification of Vehicle System Faults & Health, Safety and Good Housekeeping in the Automotive Environment
Apply a structured six-step diagnostic routine (verify complaint, gather data, analyse, test, repair, confirm) to at least four written fault scenarios and record the reasoning at each step
Distinguish between symptom, root cause and consequential damage in ten short case descriptions, justifying each classification
Carry out a risk assessment for three workshop tasks (fuel system work, hybrid high-voltage isolation, working at height) listing hazard, likelihood, severity and control measure

Demonstrate correct segregation and disposal routes for workshop waste streams including used oil, brake fluid, refrigerant and lithium cells
Your checkpoint
A written diagnostic log covering four fault scenarios with test choices justified, plus three completed risk assessments and a one-page waste segregation chart
Diagnosis and Rectification of Vehicle System Faults & Advanced Vehicle Electrical and Electronic Systems
Interpret live sensor data and oscilloscope waveforms for crankshaft position, camshaft position, MAF and lambda sensors, explaining what each deviation indicates
Explain CAN, LIN and FlexRay bus topologies and describe how to test a CAN network for short-to-ground, short-to-battery and open-circuit faults using resistance and voltage measurements
Diagnose a no-start condition logically by separating fuel, air, compression, ignition and control-signal causes, listing the test that eliminates each
Read and interpret a wiring diagram to trace a circuit from fuse through relay to component and identify likely failure points
Interpret freeze-frame and readiness monitor data to decide whether a fault is intermittent or permanent
Your checkpoint
A network and sensor diagnostics portfolio: annotated waveform interpretations for four sensors, a CAN bus fault-testing procedure, and a completed no-start diagnostic flowchart
Advanced Vehicle Electrical and Electronic Systems & Diagnosis and Rectification of Vehicle System Faults
Explain the operation of common driver-assistance systems (adaptive cruise, lane keeping, automatic emergency braking) and the calibration requirements after windscreen or geometry work
Describe high-voltage safety procedures for hybrid and electric vehicles, including isolation, PPE, lockout/tagout and the sequence for safe system disable
Diagnose charging and starting system faults using voltage-drop testing rather than parts substitution, and state acceptable drop limits
Explain how ECU software updates and coding are carried out and why battery support and post-update relearn are required
Interpret body control module fault codes and describe how to test a multiplexed circuit with a break-out box
Your checkpoint
A written technical report on one ADAS or high-voltage system covering safe working procedure, diagnostic approach and post-repair calibration or verification steps
Complex Engine and Powertrain Repair and Overhaul
Measure and interpret cylinder bore wear, taper and ovality, and decide whether to rebore, hone or replace
Describe the inspection and measurement of crankshaft journals, bearing clearances using plastigauge and micrometer methods, and thrust clearance
Explain valve train inspection: valve seat angles, guide wear limits, spring free length and camshaft lobe wear measurement
Sequence a full engine strip-down and rebuild, listing torque and angle tightening stages, stretch bolts and lubrication points
Explain timing belt and chain setup, including timing marks, tensioner setting and verification of correct timing before first start
Your checkpoint
A component measurement record for one stripped engine with measured values compared against manufacturer limits and a written rebuild decision for each component
Complex Engine and Powertrain Repair and Overhaul & Transmission and Driveline Systems
Describe the construction and repair options for manual gearboxes, including synchromesh, bearings and shaft end-float measurement
Explain torque converter, clutch pack and valve body operation in an automatic transmission and outline the diagnostic value of line pressure and stall testing
Diagnose driveline vibration and noise by distinguishing wheel balance, CV joint, propshaft phasing and differential bearing causes
Describe differential setup, including pinion depth, backlash measurement and contact pattern interpretation
Explain dual-clutch and CVT architectures and the specific service and diagnostic considerations for each
Your checkpoint
A transmission and driveline fault matrix matching at least eight symptoms to probable causes, the confirming test and the recommended repair
Chassis, Steering, Suspension and Braking Systems
Measure and interpret steering and suspension geometry angles (camber, caster, toe, thrust angle) and decide which adjustment corrects a given tyre wear pattern
Inspect and test shock absorbers, springs, ball joints, bushes and wheel bearings, stating pass/fail criteria for each
Explain ABS and ESC hydraulic modulator operation and describe how to diagnose a wheel speed sensor fault using live data
Describe brake system inspection and measurement including disc thickness, runout, pad wear and fluid testing, and explain hydraulic bleeding sequences including ABS units
Diagnose common braking faults such as judder, pull and long pedal by linking symptom to measurable cause
Your checkpoint
A chassis diagnostic workbook containing four tyre wear case studies linked to geometry causes, plus a completed brake inspection checklist with pass/fail criteria
Vehicle Inspection, Testing and Quality Control & Planning, Organising and Supervising Technical Work
Prepare a pre-delivery and end-of-work inspection checklist that covers function, safety, fluid levels, torque verification and road test criteria
Explain the purpose and content of a quality control sign-off and how to document a rectification so it is traceable
Plan a complex multi-day repair job: sequence operations, identify parts and tool lead times, and allocate technician time
Describe how to supervise and brief a small team, including delegating tasks, checking work and handling a technician who is behind schedule
Explain how to record and escalate a defect found during inspection that is outside the original job scope
Your checkpoint
A job plan for a multi-day repair including task sequence, resource list and time allocation, plus a completed quality control sign-off document
Customer Care and Communication & Health, Safety and Good Housekeeping in the Automotive Environment & Vehicle Inspection, Testing and Quality Control
Explain a technical fault and its cost to a non-technical customer without jargon, and handle a complaint about repeat failure constructively
Prepare a written estimate and job explanation that states what will be done, why, and what the customer must decide
State the legal and good-practice requirements for vehicle handover, including documenting advice given and refused
Revise all nine domains using a self-test of at least 60 questions, targeting any domain scoring below 70 percent
Confirm readiness by listing the three weakest areas and the specific action to close each before assessment
