ECU Locator Pro

ECU Locator Pro shows you exactly where your car's ECU (engine control unit) is — in seconds, with no login and no ads. HOW IT WORKS • Select your vehicle: make, model, generation and engine. • See the ECU's location marked on an engine bay diagram. • Browse real photos of the ECU in place, with the exact spot pinned. • Some engines use more than one ECU depending on production year or market — switch between them to see each one's own location. SW FINDER Found a code on the ECU's label but don't know which unit it is? Type any part number, software number or serial number and SW Finder narrows it down to the most likely ECU, with a percentage match. GUIDE Learn the five main control modules (Engine ECU, Transmission, ABS/ESP, Airbag, Body module) — what each one does, where it's usually found, and typical failure symptoms. Includes a safety checklist to follow before removing any control unit, and answers to common questions. Available in 12 languages. Missing your vehicle, or spotted something wrong? Send us a report — with photos if you like — right from the app, and we'll fix it. ECU Locator Pro is completely free. No account required, no ads, no tracking.
