Headlights, Power Locks, Hazard lights, Cabin Lights, Signal lights ALL WORK -but Cannot Power Car

Welcome to PriusChat!!

Any OBD2 codes (DTCs) that you can share with us?

Be sure to test the 12v battery voltage at both the battery, and at the jump points under the hood on the drivers side.

Sounds like there could be a problem with the dash, here is a thread for a DIY combination meter fix.

You can also find another lifetime warranty option here : Prius Speedometer Replacement

 

That's a lot of jump starting. At any time, did the cable polarity get reversed, even for a moment?

 

put a charge on the battery, or try jump starting again

 

Whatever your issue is, it doesn't seem to be one that is commonly reported here. No lights at all on the dash, not even the Theft Deterrent one that is normally blinking, correct? I know you said you have the Smart Key disabled, but what would happen if you enable it? Will the car recognize the key when you approach it and light up the interior lights? Do you hear any of the normal sounds when you push the Power button (brake actuator buzzing when you are attempting to start the car, clicking of contacts near the HV battery as they are energized by the 12V)?

 

Inside the underhood fuse box, on the left side, is a see-thru fusible link assembly. It has several 'links'. Take a look at them and see if any are open. Most times, its the one in the upper right corner that opens due to a 'mis-jump', but maybe something else is going on and a different one opened.

or maybe the power source ecu has died.

 

That truly should be your last resort, and if you need to get the car back on the road right away, that is probably your best option. However, you have not indicated that you have attempted to read any of the codes that the car is reporting. It is possible that you are not getting any power to your OBDII port, which you would need to get the codes, but if you can wait a few days for a code reader to be delivered, that might be worth a shot. Ideally you would get a mini VCI cable with Techstream, but even a generic reader with an ELM 327 chip could provide some useful information that could point you in the right direction.

 

Your hybrid battery died. Seeing this alot with people not driving an old G2 and letting it sit. Can't let an old hybrid battery sit like that especially if its outdoors in the sun with no windshield shade.That intense cabin heat over days and days will kill that battery.

Dealer will tell you the same. It will throw a P0A80 code. Replace hybrid battery pack.

Its the #1 post on this site for G2's. Go on any G2 forum and start reading about the hybrid battery.

 

I'm not really sure. It probably depends on whether you are getting power to the OBDII port or not. From my point of view, the generic reader is a useful tool, is generally reliable (compared to the mini VCI cable needed for Techstream, which has a mixed record depending on the source from which it was obtained) and is inexpensive ($20 or less). With the capabilities of new mobile phone apps like Dr. Prius and Hybrid Assistant, I believe every owner of an older Prius should have the tool. Hopefully it will help in your particular situation, but that is not certain.

 

Both of those obd devices you showed are worthless to you they will not pull hybrid codes.. You need a obd that has Toyota techstream.
The mini vci is good but sometimes hard to set up requires a burner laptop like most hacked TS devices.

There's literally thousands of posts about how to rebuild a hybrid battery please start browsing and reading and using the search forums tab up top.

 

Au contraire, the Vgate Bluetooth dongle, if it is the genuine thing and not a knock-off, will function together with Torque Pro or Dr. PRius, with which you can retrieve codes. But it will limit your diagnostic ability as it will not retrieve INF (or sub) codes nor enable you to look at freeze frame data. You can look at some live data, though.
