In the summer of 2020, Opel unveiled the second-generation Mokka subcompact crossover. It is based on Stellantis’s CMP platform, which also underpins the Corsa, Peugeot 208, Peugeot 2008, and DS 3 Crossback. The previous generation was built on GM’s Gamma II platform. Below is a comprehensive guide to the fuse box diagrams for the Opel Mokka B (second generation; CMP platform) covering the 2020, 2021, 2022, 2023, and 2024 model years.
Below you will find the location and layout photos of each power distribution module. Fuses for critical components like the “Cigarette Lighter / 12 V Power Outlet” and “Fuel Pump” are highlighted in bold.
Engine Compartment Fuse Box
The underhood power distribution center is located on the left side of the engine bay, adjacent to the 12 V battery. Unclip and remove the protective cover to access the fuses.
