I recently bought a 2013 Elantra. I started having problems with both hard starting and the transmission locking in 6th gear. No lights on the dash but my scanner showed the P605 code which is the ECU. I’m planning on getting to the dealership but I’ve read about a reset procedure involving pulling the fuse. The problem is there are two different fuses that say ECU, ECU4 and ECU2. Which one resets it?
