Fuse Box Locations and Fuse Designations
Mercedes-Benz E-Class W212

Applies to U.S. E-Class model years 2010, 2011, 2012, 2013, 2014, 2015, and 2016.

If you replace any fuses, replace each fuse with the same type and amperage rating. If there is an underlying problem, you could overload the wires or even cause more severe problems to that circuit if you use a higher-ampere fuse. Ensure the new fuse you are installing has the same color and ampere rating as the old one. If you install a new fuse and it blows again soon, you could have a short or a problem with that circuit, and have the circuit diagnosed. Before changing a fuse, secure the vehicle, switch off the engine and all electrical consumers, and remove the SmartKey. On a KEYLESS-GO vehicle, open the driver door so the electronics enter status 0. Confirm that all instrument cluster lamps are off. Never bridge a fuse or install one with a higher amperage. Keep the open fuse box dry.

You can get a lot of fuses for cheap on Amazon, like these here. Make sure to replace the fuses with the correct color and amperage rating. If the fuse tests good and the problem persists, if the fuse tests good, check the power supply, ground, connectors, wiring, switches, and the affected component. On module-controlled systems, scan all control units for fault codes and communication errors. The next step is reading fault codes with one of the best OBD II scanners for Mercedes-Benz.

How a Full System Scanner Helps With Electrical Diagnosis

A scanner does not test a fuse directly. After confirming the fuse, power supply, and ground are good, use the YOUCANIC UCAN-II Pro to read all Mercedes systems, view live data, run active tests, and perform supported adaptations and resets. It includes full AI Diagnosis, built in TPMS sensor programming, a rear VIN scanning camera, coverage for 140+ makes, 3,500+ active tests, and 1,000+ special functions. There is no subscription, and no AutoAuth is required.

Overall, the YOUCANIC full system diagnostic scanner is invaluable for any Mercedes-Benz owner or technician looking to troubleshoot problems quickly and accurately. With its user-friendly interface and powerful diagnostic capabilities, you can save time, money, and frustration by diagnosing and resolving issues with your Mercedes-Benz quickly and efficiently.
