Learn about Citroën Relay II / Jumper II 2011-2012 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.

The Citroën Relay II / Jumper II (2011-2012) is a versatile commercial vehicle available in various body styles, including panel vans, chassis cabs, and minibus configurations. It offers flexible cargo and seating options, making it ideal for businesses and transport. Key features include efficient diesel engines, spacious interiors, and advanced safety options like ABS and parking sensors.

The fuse box, located under the dashboard and in the engine bay, protects electrical systems such as the lighting, central locking, and infotainment from electrical faults by disconnecting power if a fuse blows.

The relays control essential functions, including the engine starter, cooling fans, and fuel pump. These relays allow smaller electrical currents to manage larger systems, ensuring proper operation of critical components. If a relay fails, it may cause starting issues or cooling problems, affecting vehicle performance.

Regular maintenance of the fuse box and relays is essential to keep the Citroën Relay II’s electrical systems functioning smoothly, ensuring optimal performance for both commercial and passenger use.

WARNING

  • Never replace a fuse with one that has a higher amperage rating.
  • A fuse with a too-high amperage could damage the electrical part and cause a fire.
  • On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
  • If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
  • Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
