Mazda 2 DE/DH (2007-2014), the second-generation Mazda2, uses an engine-bay fuse and relay carrier and a smaller fuse panel in the passenger compartment. The 40 under-bonnet positions and 16 cabin positions are shown separately below, including unpopulated slots and options fitted only to certain markets, engines or trims.
This guide preserves all 56 original fuse positions of the Polish article. The layout applies to the illustrated DE/DH fuse carrier, but Mazda changed engine management and optional equipment circuits during production. The label under the original fuse-box cover and the handbook for the vehicle’s market are the correct references before fitting a replacement of a particular amp rating.
Where are the Mazda 2 DE/DH fuse boxes?
Engine compartment: park safely, switch off the ignition and wait for the cooling fan to stop. Open the bonnet and find the large, black covered fuse box close to the battery. Press the cover retaining clips, lift the lid and match the numbered drawing with the panel inside. Major ignition supply fuses IG KEY 1 (40 A) and IG KEY 2 (30 A) are not ordinary accessory feeds; follow the manufacturer’s battery isolation instructions when checking bolted or high-current links.
Passenger compartment: on a left-hand-drive Mazda2, open the driver’s door and look at the lower side of the dashboard by the footwell, behind the removable trim cover. Open the cover carefully, locate the numbered cabin positions and use insulated fuse pullers for suitable blade fuses. Access can differ on right-hand-drive models. Refit the cover securely to prevent accidental contact with the wiring.
Engine compartment fuse carrier – all 40 positions
The under-bonnet box protects fuel pump, injection, headlights, the central door locking system, ABS/DSC stability electronics, cooling fan and cabin blower. The empty positions are deliberately included: an unused FAN1, FAN3, GLOW or ENG INJ2 cavity on this fuse card must not be filled merely because a similarly named component exists in another Mazda2 variant.

Petrol, diesel and optional equipment differences
Diesel-specific glow or fuel-heater protection may use positions that are vacant on the illustrated petrol-oriented arrangement. DSC-P (30 A) and DSC-V (20 A) are fitted only to vehicles with the corresponding stability-control system. Further differences can affect DC-DC, automatic transmission and headlamp high-beam circuits. Compare the printed fuse identification and engine code with the installed vehicle.
Different Mazda2 markets can have alternative fuse numbering even within the same body generation; do not substitute a fuse card from a newer Mazda2 DJ or the related Ford Fiesta solely because the models share some engineering.
Common Mazda 2 DE/DH electrical faults
12 V socket stopped working: check cabin CIGAR number 3 (15 A). Inspect the socket and removable charger for a short if the replacement fuse immediately fails. Front wipers stopped: check cabin F.WIP number 8 (20 A), followed by the wiper linkage and motor. The rear wiper has its own R.WIP number 9 (10 A).
Cabin blower does not operate: inspect under-bonnet BLOWER number 40 (30 A), then the motor and fan speed controller. One dipped beam failed: the right lamp uses H/L LO RH number 23 (15 A) and the left H/L LO LH number 24 (15 A) in this version. Check bulb, connector and earth before replacing other parts.
Electric windows failed: the engine carrier P/W number 4 (20 A) and cabin P/W number 16 (30 A) are separate supplies. If one window fails, inspect its switch, regulator and the wiring in the door aperture. Central door locking failed: check under-bonnet D/L number 15 (20 A), then investigate locks and wiring.
DSC/ABS warning illuminated: check DSC-P number 7 (30 A) and DSC-V number 8 (20 A) only if the particular vehicle is fitted with those modules. An intact fuse does not exclude a faulty wheel-speed sensor or control module.
