2012 Prius: How to reset or get "check hybrid system" dash light to shut off?

Remove battery negative lead from battery, let sit for a few minutes, reconnect. Reset the "auto down" windows and all your radio station presets.

 

I've always been told to turn the car on and off 3 or so times. If the error doesn't clear, something may indeed be wrong.

 

Oh boy...

 

If you believe the negative battery cable, or the 12v battery all together, is located under the hood then I question if you really did cause any serious harm to your car initially. The 12v battery is in the rear of the vehicle. If the error doesn't clear after several car restarts, take it to your dealer if it's under warranty.

Refer to your manual if you'd like to take the issue into your own hands and wish to disconnect the (-) cable from the (-) battery terminal.

 

You need high voltage gloves in order to safely disconnect it.

All kidding aside, it is in the right rear corner of the trunk. The terminal is on the soft side so be careful.


iPhone ?

 

Turn it off and on 3-4 times, it will go away.

 

Look at your manual.

 

If you have pulled the orange circuit breaker in the trunk and get a Hybrid system failure. Check to see if you failed to slide the orange handle to the lock position when you reinstalled it. Moves right. You may need to still reset the codes by disconnecting the 12 volt battery. Fire department says this is not necessary. This will reset the warning message.

Excellent theft deterrent when parked in long term parking at the airport. Just slide it to the left.

 

Kind of crazy but I had this happen to me after I connected my Progressive get your discount thingie. I found that not only do you have to cycle the power switch but actually drive around the parking lot. It cleared for me after four resets with the motor cranking up.

 

I have a circle driveway. I just drove around it. The fourth time that I powered up it cleared. I had tried it without moving and it just didn't do it.

 

Better explanation:

The Prius swerved unexpectedly and hit the median.

Two tires blew and ruined two rims.

The car was towed home.
It was started several times and moved fine.

The tires and rims were removed and replaced.

Disconnected my hybrid battery lock many times and reconnected.

disconnected the negative pole of the 12V battery and reconnected

still get the message;

Check Hybrid System.

vehicle will not move or go into gear.

 

yeah right.... /

 

Sounds like you still have undiagnosed damage from the offroad incident. Needs proper diagnostics to evaluate. Toyota Techstream software would be best, but even retrieving an error code with a simple 'dumb' code scanner would be a good start.

Just hazarding a guess, there's either physical damage or water intrusion to the high voltage wires under the car relating to going off the road. A real diagnosis will be needed.

 

Presented with a code reader, the car will give trouble codes explaining why it thinks it is showing that message. That's where the diagnosis starts.

 

Last year a car hit the local highway guard rail, driver said a wind gust caused the car to swerve. Last heard the wind's insurance premium went up.
