Mod Details Premium No Difficulty Mod ID 1563 Credit evilution For Link https://evilution.co.uk/mod/600cc-secondary-fuse-box.htm Copy to Clipboard Secondary Fuse Box The 600cc smart fortwo (1998 to 2002) (or city-coupe and city-cabrio as it was called back then) had a ZEE unit under the dash instead of the SAM unit as found on the 700cc fortwo. The ZEE unit didn’t have many fuses or relays so smart added an extra fuse and relay box underneath the nearside seat, under the carpet. It was power and switching for parts of the engine and transmission. Because it controls power to the transmission, it’s one of the reasons you could be experiencing the 3 bar transmission fault . You don’t have to remove the seat but it does make things easier. You can push the seat forward and work between the gap in the carpet. You’ll see a long thin black box with 3 connectors. Held each end with a 10mm plastic nut. The relays and fuses are protected by a cover… …which is held in place with 3 clips. Lever the clips away and remove the top to reveal the relays and fuses. The lid contains numbers and letters that probably mean something to smart.
