The computer in a car does not need to be reprogrammed if the battery light keeps coming on. The battery light is a warning light that indicates that there is a problem with the charging system. The most common cause of a battery light coming on is a loose or corroded battery cable, but there are other issues that can cause the battery light to come on, such as:
- A bad battery
- A bad alternator
- A bad voltage regulator
- A faulty wiring connection
If the battery light is coming on, it is important to have the car diagnosed by a qualified mechanic to determine the cause of the problem and have it repaired. Reprogramming the computer will not fix the problem and may actually cause other problems.
