Online automotive training for Indian technicians. Diagnostics, electrical and electronics troubleshooting — taught step by step, in Hindi and English, with real workshop examples.
Start free with diagnostics. Go deep with electrical and electronics troubleshooting.
Diagnose vehicles like a professional — from the OBD port to live data, special functions, flashing and online programming.
Wiring, fuses, relays, sensors, actuators, signals and modules — for cars, trucks, 2-wheelers and 3-wheelers on petrol, diesel and CNG.
Diagrams and animations that make the circuit make sense, in 15–18 minute lessons.
The same test performed on a real vehicle — Maruti, Tata, Hyundai, Mahindra and commercial vehicles.
The errors technicians actually make on that job — and how to avoid them.
Notes with every lesson, made to keep open while you work.
Check what you learned before moving to the next part.
Live sessions every Monday morning and Tuesday evening.
Battery handling, airbag (SRS) circuits, ECU handling and static protection, high fuel pressure in diesel common rail, high voltage in ignition and injector circuits, and high-pressure CNG systems.
Cars, trucks and 2-wheelers. PDF notes with every lesson, quiz at the end of every level.
Learning path: Basic (Part 1) → Intermediate (Parts 2–3) → Advanced (Parts 4–5) → System Troubleshooting (Parts 6–8). New to electrical work? Start with Part 1. Experienced? Jump straight to the part you need.
Wiring, fuse, relay and circuit testing. Read any wiring diagram, use a multimeter like a professional, and find open, short and voltage drop faults. 11 lessons
Every sensor by property and by working — resistance, hall effect, inductive, chip-based, O2, NOx, knock. Test any sensor, even one you have never seen. 17 lessons
Solenoids, DC and stepper motors, heaters, piezo, ignition coils and module-controlled actuators — with power, control, resistance and current testing. 15 lessons
Analog, digital, frequency and PWM signals, oscilloscope basics, sensor and actuator waveforms, CAN and LIN network signals. 7 lessons
ECU, BCM and module power, ground, inputs and outputs. Test a module properly before calling it faulty — including 24V truck modules. 7 lessons
Petrol EMS troubleshooting for cars and 2-wheelers — fuel supply, air management, misfire, emission control, crank-no-start and mileage complaints. 8 lessons
Common rail and BS-VI truck troubleshooting — low and high pressure systems, injectors, turbo and EGR, aftertreatment, and commercial vehicle case studies. 8 lessons
Factory-fitted and retrofit CNG systems — safety, CNG electrical system, injectors, reducer and sensors, running faults, 3-wheelers and commercial vehicles. 6 lessons
Three more courses are in production. Syllabus and dates will be announced on this page.
Electric vehicle systems for workshop technicians — high-voltage safety, battery, motor, controller and charging system diagnosis.
Commercial vehicle specialisation — 24V systems, BS-VI truck electronics, aftertreatment and fleet fault finding.
ECU and module level repair — component identification, driver circuits, board level fault finding and safe rework.
Move from replacing parts to finding the actual fault.
Practical training that the classroom doesn't cover.
Train your whole team on one standard method.
Sensors, actuators, modules and networks in depth.
Indian language versions are in production. Same lessons, same notes — in the language your team actually works in.
Car Tool India was built to solve one problem — Indian workshops struggling with modern vehicles. A tool alone does not fix that. Garage Gyan is the training side of the same promise: the method behind the tool, explained in the language technicians work in, with real vehicles and real faults.
Garage Gyan is the online training app from Car Tool India. It teaches automotive diagnostics, electrical and electronics troubleshooting to workshop technicians through video lessons, PDF notes, quizzes and live doubt-clearing sessions.
Hindi and English at launch. Tamil, Kannada, Telugu, Bengali, Gujarati, Marathi and Punjabi versions are in production.
Yes. The complete 16-lesson Automotive Diagnostic Course is free. In the Electrical and Electronics course, 14 lessons are free — Part 1 lessons 1.1 to 1.7 plus the intro lesson of every other part.
Workshop technicians, ITI and polytechnic students, workshop owners and freelance auto electricians who work on petrol, diesel and CNG vehicles.
The app launches on 28 September 2026. The Automotive Electrical and Electronics Troubleshooting course follows on 15 October 2026.
EV Training, Truck Masters and Module (EMS) Repair are in production. Syllabus and dates will be announced on this page.
