Visteon DCU102: OBD Virtual Read and Boot Normal Read on AutoTuner Tool

Dear Users,

We are pleased to announce that the Visteon DCU102 engine control unit is now officially supported via OBD Virtual Read (VR) and Boot Normal Read (NR) on your AutoTuner Tool. This protocol covers European light commercial vehicles across Citroën, Peugeot, and Fiat models from 2002 to 2006, specifically the Citroën Jumper, Peugeot Boxer, and Fiat Ducato powered by the durable 2.2 HDi and 2.2 JTD diesel engines.

💡 ECU Spotlight: What You Might Not Know

Why does a French and Italian commercial van carry an engine management system developed by an American automotive electronics giant? 🤔

The answer is the Visteon DCU102 (Diesel Control Unit). Visteon was Ford's own electronics division until it became independent in 2000, born from the same Ford–PSA diesel partnership that shared engines between both groups. It manages the 2.2 HDi / 2.2 JTD of the 2002 Jumper and Ducato, and the Ford link goes even deeper on the 2006 Jumper and Boxer: their 2.2 HDi is in fact Ford's own 2.2 "Puma" turbodiesel.

Built around the STMicroelectronics ST10F276 16-bit microcontroller, the DCU102 is made for workhorse duty: delivery fleets, campervans and ambulances. These vans came off the line at Sevel Sud in Atessa, Italy, a Fiat–PSA joint venture often described as Europe's largest light commercial vehicle plant.

👉 One ECU, three brands, two generations of vans: now you can read and write them all with your AutoTuner Tool.
