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+).
A starter relay switch is an electrical component found in vehicles that completes a circuit between the battery and the starter motor when the ignition switch is activated. The starter relay isolates the ignition circuit from the much higher current that the starter motor requires to operate. Keep Learning.
