Vehicle Electrical System Reset

If you didn’t use a memory saver, you might need to reset certain vehicle systems.

Your radio presets and clock will likely be reset. Some vehicles might require the power window “auto up/down” feature to be reprogrammed (usually by holding the window switch up for a few seconds after the window is closed). Drive your truck for a bit; the engine’s computer (PCM) will relearn idle parameters and shift points. If you notice any persistent issues, a full vehicle electrical system reset might be needed, which can sometimes be done by disconnecting the negative terminal for 15-30 minutes, or by a diagnostic tool.

Monitoring Your Charging System

A new battery won’t last long if your alternator isn’t doing its job.
