2005. Problem. All warning lights are on. Wont start.

The Red triangle with the ! indicates a general fault in the Hybrid system. Sounds like a tow to the dealer... Sucks.....

 

What makes you think the 12v is fine?
Testing with a voltmeter under load, or with a battery analyzer might be a good idea.

Get the codes read and report back here.
Then we can better help point you in the right direction.

 

That looks like a nice charger.
Does it actually test battery health as well?

If not then you may want to check voltage while the car is under load. (Using a voltmeter or other test).

If you have a few days to wait, you could order a Bluetooth OBDII reader, and download the Torque app to an Android device. Cost you less than $25 via Amazon and you'd have it quickly.

Then you could scan the car yourself. Cheaper than towing it. Or having mechanic or dealer scan it.

Low oil can make the car throw codes. But you can check the oil level yourself. Do some Google searches if you are not sure how to do it. Refill with the oil marked in your oil filler cap.

Feel free to call me if you have any questions in the meantime.

 

This looks maybe brake actuator, if you're lucky it has extended warranty

Guessing what's wrong from far away is a hard task.
If I were stuck in an isolated location with no access to a scanner, could eventually figure it out.
But getting a quick scan saves hours of time and keeps you headed in the right direction when trying to diagnose.

 

No it does NOT "test" anything......beyond making sure the battery is not a dead short before trying to charge it.

You NEED the services of a shop.

 

You also need to know that a failing 12 V battery can throw all the internal computers off.......so that they spit out "trouble codes" that may have nothing to do with the actual problem.

The 12 V battery is a critical component and needs a proper test (or replacement if it is old) before you waste your money chasing ghosts.

But you don't have to take my word for it. Just do a search on here for "battery". About a million matches will come up.
Split about half and half between the 12 V one and the HV hybrid one.

 

I found this from searching on PriusChat:

"DTC C2318 does imply that 12V bus voltage is low, which may be due to a failing 12V battery. Since that is the cheapest and easiest item to replace, I'd suggest starting with that." - @Patrick Wong

 

In your first pic, the display seemed to show nothing in the state-of-charge (SoC)...???

 

Assuming you mean the 12 volt battery: I would suspect the dealership already checked it, but who knows. If you want to be sure, yeah try auto zone, assuming they have digital load testers.

The charger you're using: how old is it, and is it capable of charging at lower amperage rate?? If you look in owners manual I think you'll see max charge rate recommendation around 3~4 amps. Also, I would highly recommend to get an up-to-date smart charger, in the 3~4 amp range. I use a couple of CTEK's, a 3300 and a 4.3, fwiw.

Also, you can do a rudimentary check of the 12 volt by checking the voltage with a digital volt meter. For more in-depth test, something like Solar BA5 will do digital load test; it's prosumer level version of what Auto Zone might have.

 

Simplest way to test 12V AuxBattery is to switch on all lights and see if they dim significantly as the load is increased.
Next simplest way:
- Without brake pedal, press the Power button once and release to enter ACC mode
- Press and hold the MFD Info button, then turn the headlights on and off three (3) times to enter Maintenance mode; release Info button
- Press “Menu” (on screen)
- Press “Display Check”
- Press “Vehicle Signal Check” - the battery voltage is shown and should be about 12.4 to 12.8 Volts (normal for an unloaded battery)
- Again without brake pedal, press Power button and release to put a current load on the battery - the voltage should stay above 12.0V (if less than 12.0V the battery is not well, or there is a fault or unusual load somewhere)
- Press brake pedal and press Power button once to enter "Ready" mode - the battery is now charging at about 14V (if less than 13.6V or more than 14.4 there may be a problem with the charging circuit)
- Turn car OFF to leave Maintenance mode
