P lock malfunction 2012 Prius

I have the same problem and just looked at most of my fuses and they seem fine. I don't have a tester. I think my 12v battery is low now. I can't unlock the back hatch. I have a battery charger that I've never used. I'm a bit skittish to hook it up since I've read so much about the dangers of dealing with the 12v battery.

Wondering if I should just tow to dealer?

 

What's the charger? A smart charger, around 4 amp, should be no problem. Hook up at the jump point.

 

if your skittish, tow it to the dealer. and don't charge the battery, replace it if it's original.

 

The charger is a BatteryMINDer 12v 2amp. I hooked it up and it said my battery is weak and it was on the lowest level it shows as far as how charged it is. I suspect I'll still have to tow it and since I've had the car over 7 years now I guess I should replace the battery.

Now I just have to worry that I'm in Los Angeles, it's after dark and I park on the street so I have the electrical cord running out my kitchen window to the street and have the hood slightly open. I'll have to shut down the operation soon, too bad I can't leave it charging overnight.

Thanks!

 

yes, you should. but there might be a cheaper alternative to towing. call around to see if someone will install in your driveway.
alternatively, put the charger on the jump point under the hood overnight to see if it will start, so you can drive it to the dealer. red/positive to the jump point, and negative to a ground. it's not that hard.

 

UPDATE: Charged the battery for the last 6 hours and the car started! Going to borrow my neighbor's car in the morning to go buy a new battery.

 

There is a sensor under the brake pedal which determines if it's being pressed. This sensor is used to allow you to start the car, and also to illuminate the brake lights. Have someone stand behind the car to check that the brake lights come on when you depress the brake pedal. If they don't come on, it's probably this sensor, which is fairly cheap and perhaps just needs alignment and not even replacement.

You should test voltage from inside the engine compartment and not directly from the. Artery terminals. There's a jump starting block described in the owner's manual, and it is under the hood. If your battery ground is bad, for example, you'll get good voltage from the battery terminals but you'll still be under voltage.

 

Hello Try using contact cleaner in the fuses box
Pull out one by one fuse clean the leads with sandpaper and add contacta cleaner to every female socket of the fuse
I had the same trouble after of using presume air over the fuses box
