Re: Leaf won’t start or charge - 12v is good

A voltmeter and good quality 12V charger are worth having in your tool kit. The laef is known to be poor at keeping the aux battery fully charged and desulfation with an external charger is necessary if the car sits unused for a week. New batteries from the auto parts stores need to be desultate-charged also--no telling how long it sat on the shelf. Without even some basic voltage measurements it is just blind troubleshooting.

That's great news, glad you solved the problem and got it working again.

Was the replaced module determined to be bad due to having lower voltage than all the other modules, or did it exhibit failed insulation resistance, e.g. you could read a voltage between the module terminals and it's case? This would help us in troubleshooting the P0AA6 DTC in other cars.

Yes according to my mechanic it had a much lower voltage than the other cells that’s why it had to be replaced. I have no idea how he read the voltage or which module was replaced. The mechanic seems to say a different thing everytime.
