Suzuki SX4 – fuse and relay

Mini crossover Suzuki SX4 is produced in 3 generations from 2006 to the present with hatchback and sedan bodies. 1st generation was collected in 2007, 2008, 2009, 2010, 2011, 2012. 2nd generation in 2013, 2014 and 2015. Since 2016, the third generation Suzuki CX4 has been supplied to the markets (2017, 2018, 2019, 2020, 2021). Although some consider it to be a restyled version of the second generation (Suzuki New SX4 / S-Cross SX4). Since the update mainly affected only the appearance of the SX4. In this publication you will find a designation of the Suzuki Cx4 fuse boxes and relays. We will also show box diagrams, photographs and their locations. Let’s highlight the fuse responsible for the cigarette lighter.

The design of the boxes depends on the year of manufacture, and the purpose of the elements depends on the level of equipment, the type of car body and the country of delivery (besides the Europeans, there are also Japanese and American SX4s). Check the description with your own on the back of the protective cover.

    Hello Aliaksan,

    Do you happen to know the part number for the turn signal relay

    Supposedly this relay is 7 or 8 pins and located under the steering column.

    Actually, I am looking to replace the original by an electronic one to accommodate LED turning signals.

    1/ Would you happen to know the P/N of the original, an LED compatible substitute, and have a circuit diagram? … am I asking for too much 😉

    Anything you can help with would be awesome.

    Thank you!

    You have an awesomely documented website – Kudos to you and anyone that may be helping you out 🙂

  • From Ricardo: Left hand side, bottom, driver side – the turning signal relay is located behind the fuses, towards the firewall or engine (front). Regrettably, I have not had a chance to access it yet. I just felt it after following the ticking.
