[QUOTE="SCGallo2, post: 16409773, member: 160791"] Increased electrical load can expose a weak alternator. Review the datalog where the DTC occurred, if battery voltage was being logged (it should be). You should be able to see where the voltage drop occurred. Then see if you can repeat the event under the same conditions while datalogging. If you end up replacing your alternator, don't replace it with an OEM unit... they are hit or miss on quality and usually end up failing again. Here is my ordeal: [URL]https://www.svtperformance.com/threads/how-well-is-your-alternator-performing.1159061/#post-15898038[/URL] [/QUOTE]
