🔧 Product Description

Genuine Volvo Penta wiring harness for the DCU (Display Control Unit) cable, from the Cables and Fuses group, weighing 0.199 kg and listed for 69 applications across TAD and TWD series engines. The DCU designation identifies which circuit it serves, and broad fitment makes it a commonly required item.

🚤 Compatibility

  • Engine Family: TAD, TWD

Full model list at the end of this description.

⚙️ Key Features

  • Cable for the DCU
  • 0.199 kg
  • Listed for 69 applications across TAD and TWD series engines
  • Broad fitment across the range, so a commonly required item

🔌 Function

Connects the display control unit to the engine's electrical system, carrying its supply and the data link that puts engine information on the display.

⚠️ Common Signs of Failure

  • Display blank, dropping out, or showing faults that clear themselves
  • Readings that flicker when the loom is moved
  • Connector pins corroded, bent or pushed back in the housing
  • Cable outer chafed or crushed where it passes through a panel
  • Broken conductor or failed screen found on continuity testing

🛠️ Service Notes

  • Test the cable and check its connectors for corrosion before condemning the display unit - a dropping display is more often the cable
  • Support the cable where it passes through panels and bulkheads so the sheath is not cut by the edge
