When I try to start my car all the dash lights flash on and it does not start, after 3 or so tries it will start. What is wrong

Look at the Dash ...Is the security light ON when you enter this vehicle? When the engine does run, are there any warning lights ON or flashing?

All lights are on just flashes seccurity light is on flashing

Since this topic is 2 years old we need to reestablish the Make Modle Year of this vehicle including a history of the issue. When you first attempt to start this vehicle....will the engine CRANK over like the battery and starter motor are good...or...do you hear just a Click ?

2014 hybrid

I would also like to see the answer to this question for a 2012 Camry hybrid. All the dashboard lights flash intermittently, says "no access to BLM," and "needs maintenance" and there is just no power. The battery never indicated being low...

I think you need to have the computers on this vehicle scanned for codes. Some Auto Parts Stores will do this for Free. Suggest you call a few and ask if they provide this service. Make sure you list the numerical indicator of each code found. Good Luck.

I did reach a repair shop that works only on Toyotas and Hondas. Their first suggestion was to replace the 12V battery, and since they were closing until Monday, thought Interstate Battery would have one...but they do not, as it is a "dealers-only battery." So, if I can jump my car, they wold be the logical ones to run such a test, but the cost of this battery is $332. 1. Do you happen to know if a reasonably handy person could change this, or is a specialist needed because of higher-level computer/technical needs? 2. If I cannot jumpstart the car, would that indicate a mother-board issue? Thanks for such a speedy response, by the way!

The 12 volt battery should be located in the rear of this vehicle. It does not start the car. It supplies electricity to the many computers on board. Replacing that battery might not fix this issue. Jumping that battery is not advised. We would simply use a Volt Meter to check for voltage across the battery terminals. Should be 12.3-12.6 or more volts. From where I sit.....I would simply disconnect the wire on the NEGATIVE terminal of said battery for 5 min. Reconnect....and see if she will fire up and run. THEN i WOULD SCAN IT FOR CODES. Disconnecting the (-) terminal reboots all the computers on board. How many times has rebooting a computer fixed the problem on said computer? Worth a try? Get back with results

Thanks so much, Tony!

Tony, the problem has been resolved. This is what transpired today. I called the Toyota dealership again and found a more knowledgeable technician than yesterday, and this is what I learned: 1) With less driving due to COVID, it was possible that it just needed a jump; 2) It is perfectly fine to jumpstart "any" hybrid car 3) I happen to have a hybrid model whose battery is only carried by the dealerships. So I was able to jumpstart my car and restart it after shutting it off. All I need now, apparently, is a new battery for the fob which is something I have on hand. Thanks, though!

Wow...excellent. so the root cause of this issue was a dead 12 Volt Battery located in the rear of this vehicle? Why does the Fob battery have to be replaced?
