Turn off switch for the hybrid battery on an 07 highlander

Question edited for clarity add maker.
Question moved to model category.

Your question as written makes no sense. You made an earlier post 10 minutes before asking "How do check fuel pump is working".

Although badly written, (How do you check that the fuel pump is working?), I can answer that.

In the engine bay on the fuel rail there is a port that looks like a tyre stem called a Schrader Valve. You connect a fuel pressure gauge to it and test the fuel pressure when turning the engine over to start it. The pressure should be 44-50 PSI.

Correct, two batteries. Once your vehicle is jumped and started, the alternator will charge all the batteries, so just take it for a 30 minute highway run. Your larger Hybrid battery bank should be fully charged by plugging it in.

All vehicle owners should have a 10 amp battery charger.

You really need a Hybrid specialist for that one . It could be the engine seems to run but it's just the hybrid system turning it over , sounds like it's running .

Have you checked the 12 volt battery under the hood? If it's low it won't activate the hybrid system and the engine won't turn over at all.

The computer monitor the system and recognized a problem. After so many years and miles the battery may go bad and computer send a massage. Or something ales is bad. Hard to guess w/o scanning for code. stop buy to dealer or mechanic wit good scanner and read the code.

Wait on the specialist.

the aux battery is bad its uder the hood the generator does start the gas engine but you left the dome light on or something like that it will not turn on or switch to ready mode

You are in luck.
There are no security codes in your radio.
Nothing to worry about when you change the 12 v battery.

The hybrid battery is charged by the motor generator that is attached to the engine, and also charges during braking. Very sophistocated in how the hybrid battery gets charged.

That being said, you do NOT want to pull the battery out & attempt to charge it. There is no charger available anywhere to charge a hybrid battery. Toyota does not offer one, either. Hooking up a standard battery charger could cause disasterous results (it could explode). And, the possibility of getting shocked with over 300 volts DC is very good. When we have to handle hybrid batteries, we have to wear big, heavy rubber gloves so we do not get injured from the many contact points under the battery shell. This is not something you really want to fool with. The stakes are just too high. Sorry I was not giving you the info you are wanting, but, be safe & leave the battery alone.
