2022 Maserati Quattroporte Fuses and Fuse Box Owner’s Manual
The performance and beauty of the 2022 Maserati Quattroporte make it a desirable luxury sedan. Understanding the fuse system of this car is essential to its upkeep. The Maserati Quattroporte’s fuse box has a variety of fuses and relays that regulate the car’s electrical systems. A blown fuse may cause electrical devices to malfunction and necessitate its replacement. The covering panel in the luggage compartment must be opened in order to access the fuses and relays in the Quattroporte. Comprehending the arrangement and placement of fuses within the fuse box is vital for proficiently resolving electrical problems. For owners of Maserati Quattroporte vehicles, having a clear diagram or knowledge regarding the fuse box structure is crucial when it comes to checking for blown fuses or replacing them. Typical

If a Fuse Blows
Used Fuses Characteristics
When an electrical device is not functioning, check that the corresponding fuse is in proper working order (intact).
A Fuse intact
B Fuse blown
The vehicle mainly uses mini-and maxi fuses with blade engagement. Besides these, there are other types of fuses provided with holes for attaching to the cable connection terminals. For the replacement of these fuses contact an Authorized Maserati Dealer.
Replace the faulty fuse with a new one featuring the same rating, by using appropriate forceps added in the integrated power module and inside the cover of the rear power distribution centre.
The color identifies the value of the fuses in amperes which is also reported on them.
The table shows the match between the colour and amperage of mini and maxi fuses.

How to replace Fuse in the Maserati Quattroporte Fuse 2022
- Locate the Fuse Box:
- The fuse box in most vehicles, including the Maserati Quattroporte, is typically located either under the dashboard on the driver’s side or in the engine compartment.
- Identify the Fuse:
- Once you locate the fuse box, open it. Inside, you’ll see several fuses of different sizes and colours.
- Remove the Fuse:
- Using a pair of fuse pullers or needle-nose pliers, carefully grip the fuse you want to replace and pull it straight out of its socket. Be gentle to avoid damaging the fuse or the fuse box.
- Inspect the Fuse:
- Before inserting a new fuse, it’s a good idea to inspect the old fuse to see if it’s blown. A blown fuse will have a broken filament or appear discoloured. If the fuse is intact, the issue may lie elsewhere in the electrical system.
- Insert the Replacement Fuse:
- Take a new fuse with the same amperage rating and carefully push it into the empty socket in the fuse box. Make sure it’s seated securely.
- Test the Circuit:
- After replacing the fuse, test the component to ensure that it’s functioning properly. If the fuse blows again immediately or soon after replacement, there may be an underlying electrical issue that needs to be addressed.
- Close the Fuse Box:
- Once you’ve replaced the fuse and tested the circuit, close the fuse box securely.
- Dispose of the Old Fuse:
- If the old fuse is blown, dispose of it properly. Do not reuse a blown fuse.
