    Default First Problem P1F58 CEL

    Hi all-

    My first problem with my 2014 Volt. It just turned 30,000 and I charge on 240. Check engine light turned on after unplugging it.
    Any ideas of what this code from Onstar means, or has anyone else experienced this code?

    The Lithium-Ion Battery is not performing as expected. An issue has been detected in the Onboard Charging System which manages your vehicles battery pack charge level.

    The car is performing fine and is charging.

    I'm far from an expert at anything (don't know how I made it to retirement) but from reading stuff on here... try unhooking the battery in the trunk for a minute, then hooking it up again. This is while it is not charging or running.
    Other than that you probably gotta go to the dealer.

    The light is now out. Weird!

    I find that if I unplug the cable when just finished a preconditioning but the 240v charge is still topping off the battery, it will trigger a check engine light. It has happened to me probably a dozen times over the course of 4.5 years. The light will go out on its own after a few charge cycles but I now just use my ODBC unit to turn it off when it happens. The car performs normally. I also think if you pull the plug too quickly, it has not had proper time to sense the low voltage pilot signal loss and it thinks the 240 dropped first. That is my guess as to why disconnecting the plug may throw a,check engine light.

    The EVSE handle has a circuit in handle, so that when one presses the handle to remove it, this signals the car and the EVSE charger to turn off the main power. Turning off the high voltage so the connectors are not removed with current going to through them when removed causing an arc. So if the charging handle is removed too quickly the high voltage could be removed prior to the car recognizing the handle depress.
