A nonsense mutation in the leptin gene that results in a stop codon and lack of leptin production was first observed in mice in 1950. In the mouse gene, arginine-105 is encoded by CGA and only requires one nucleotide change to create the stop codon TGA.
The fuel pump relay, located deep inside the TIPM, is the most common relay to fail since it's powered on 100% of the time while you're driving. You likely found this website because your dealer wants to change your fuel pump ($600+) or TIPM ($1000+).
The ECM-power relay is verified that it needs to be replaced. The relay is located in the engine main fuse relay control box. The defective ECM-power relay is removed from the control box by pulling it straight up and out of socket. The new ECM-power relay is installed into the socket and the engine scanned for codes.
