Hi everyone,

Every few days I'm losing the clock, mpg and some other memory functions, when the car isn't running. This only occurs when the car is off. I measured the voltage to see if its the battery or alternator. Im getting 13.8 - 14 v on my OBD foxwell unit.

Im getting the following codes:
2deb power management vehicle electrical system
2e8c intelligent battery sensor function
2ebd - no bdm message from alternator

The car is new to me and the battery was dead when I bought it. Swapped and coded the battery with AGM battery. Im thinking it could be the intelligent battery sensor, but not sure. It seems the battery and alternator are throwing the right voltage. Any thoughts?
