Warning lights question/ where to post

Basically, when there are warning lights being displayed, there will be obd2 codes stored in the ECUs (computers), retrieving these stored codes would be the first step in diagnosing or repairing the vehicle. Find a hybrid compatible obd2 scanner and post the codes in this thread.

Unlikely. The codes are still being stored, even if you no longer have the warning lights.

How many times have you power cycled the vehicle since your near death experience?

 

Yup....

Kinda weird, because, as far as I know, the maintenance required light has only one job on a Gen 2. Starts blinking for about 8 seconds once the car has gone 4500 miles since last time it was reset, and turns solid at the 5000 mile point. It's just an oil change reminder. And it will stay solid until the reset procedure is performed.

It would be interesting if you could get codes read by techstream to see what is in there under historical.

 

You need to look in this list under scanners or OBD2 readers and see what everybody's using there's a whole bunch of them there's a whole bunch of them they don't like a few they do tech stream is the Toyota dealer software. That you can buy hacked versions of and run on a Windows computer it's all over the internet you can call it stealing if you want to No one seems to be coming after anybody about it You're working on cars that are 20 years old so we'll see how that goes legally sounds good to me I use tech stream. My girlfriend uses Dr Prius and a Bluetooth OBD2 dongle seems to work fairly well pick your poison

 

I've been using Autel MaxiAP dongle, it's cheap and doesn't require a laptop. iPhone and Android compatible. I recently switch to Xtool A30D since I have multiple brands/cars and Autel requires you to pay license every year for each brand (you have only 1 brand lifetime-free) I throw away my old windows laptop with tech stream (mini VCI) since those 2 dongles can do the job.

 

I would also check your oil level. Hard breaking can sometimes give you a very quick RTOD for a split second. Make sure your oil level is good and all coolant and break fluids are topped off as well. Then check for codes. I use an iPhone SE and the Carista ODB reader and the paid version of Dr Prius

 

When you're trying to start and ready your car where is your key while you're trying to do this and things are acting weird make sure the key or the fob is in the slot with the buttons aimed up and it's a docked correctly now do you hear the b Beeps and does it boot correctly???

 

The car doesn't care whether the buttons are up or down.

Torque Lite will be inadequate for anything but the most basic of engine codes. See the Gen 2 OBD app review thread at the top of the Gen 2 Prius Technical Discussion forum for some pointers on suitable apps to use to read codes.

 

It sounds like your 12V battery is bad. How old is your battery?
