Hello My car won’t turn on and j get error AUX BATTERY LOW WHEN PARKING . I had AAA come and juice the battery and it worked. Next day same problem car won’t turn on and I get same error. Does that mean I need to replace the battery ? Or a hybrid battery issue or what exactly?
A 12v battery that is low on charge doesn't magically get up to full charge just because AAA jumped it and you drove it around a little. You need to put it on a smart charger capable of going up to at least 8 amps for at least 12 hours if you want to address this problem.
I replaced the battery once in the laset 4 years or less. Wanted to know if it’s the regular battery or something else ? The voltage shows ok but need to run diagnostics at mechanic. I
We can't answer that question until the battery has been fully charge with a viable charger... Right now the only problem you have is your battery needs to be charged. Get that problem solved first and then we'll talk about whatever else may come up...
It’s vey likely just the 12 volt ailing. Do you have a multimeter? Check the voltage on it, first thing in the morning, car off, at the under the hood jump point. If practical, pop the hood the night before, to avoid waking the car at all.
Yes, highly likely. Not possible to tell "exactly" without being there though. The battery can be tested at any Toyota dealer, auto parts store or battery store.
