Engine control unit for heavy trucks
Tractor unit, rigid truck or site vehicle stopped by its engine control unit? We supply a genuine unit, matched to your engine serial number and shipped ready to fit.
A truck off the road means lost deliveries and an idle driver. We supply engine control units for heavy-duty diesel truck engines, mainly Cummins and Caterpillar. No light vehicles, no passenger cars.
Heavy-duty diesel only — no passenger cars.
Signs of a failed engine control unit
- The engine does not start or stalls right after starting.
- No communication with the diagnostic tool, engine warning lights on the dashboard.
- Engine cut-outs on the road, sudden loss of power.
- Unit damaged after electrical work, reversed battery or water ingress.
- Unit stolen or missing.
These symptoms can also come from the wiring harness, the power supply or a sensor. Have the wiring checked before replacing the unit: we remind you of this in the quote.
What to send us
- The engine make and model, and its serial number (engine plate).
- The part number on the old unit's label, if readable.
- The machine: make, model, year, and whether it is down right now.
- The delivery country. Photos help but are optional.
