Doyen Autos ECU Testing & Repair

Not every ECU fault means you need a replacement.

At Doyen Auto Services, we offer professional ECU testing to accurately identify electronic faults before unnecessary parts are replaced.

Our ECU testing capabilities include:

- ECU bench testing & diagnostics
- Power supply and communication testing
- CAN Bus communication checks
- ECU hardware fault diagnosis
- EEPROM & Flash data testing
- Internal component and circuit testing
- ECU fault identification and repair assessment
- Cloning, programming and data transfer where required
- ECU testing for cars, vans and commercial vehicles

We use advanced diagnostic and electronic testing equipment to investigate the ECU properly and determine whether it can be repaired, programmed, cloned or requires replacement.

Test first. Diagnose properly. Replace only when necessary.
