Would the truck fail to start because the altinator should be programmed

1 comments:

Mr. Anderson

February 12, 2025

The provided context does not mention the need to program the alternator for the truck to start. However, it does state that the Powertrain Control Module (PCM) must be reprogrammed with the vehicle's original identification number (VIN) and mileage if replaced. Since the alternator is not specifically mentioned in relation to programming, there is no indication that it needs programming for the truck to start.
