“Check Hybrid System” error

maybe the hybrid battery again? pretty common. are you using tech stream to read the codes?

 

if the battery is bad enough, it doesn't have the power to turn the engine over

 

You stated "I’m having the same error, and I was able to drive using only the gas engine for a few days.", which means the HV battery was working because that battery is what spins to engine to start it.

Then at some point, the engine would no longer start. And at a later point the dash board will not power up. This odd because all the car needs in order to power up the electronics is a good 12v battery. Perhaps the 12v has died or the connections aren't quite made up all the way.

I think you may mean you have a P0A80 code. That is "replace the hybrid battery pack". I have seen this be a permanent code and stay in memory even after the battery has been repaired. If so, it would show as a permanent code, not as a 'current' code. If it's showing as a current code, then it's new.

 

This may not be THE problem, but it is a problem that should by testing it to determine if it needs be charged or replaced.

Some scanners will tell you the status of each code. Current, pending, history or permanent.

irt the permanent, there are several threads on the forum about the Gen 3's showing a P0A80 code under the permanent status for months after the HV battery has been replaced. Supposedly it will eventually clear itself but I don't think we've ever really come to a consensus as to how to get it to clear. Even techstream isn't able to reset it, or at least not the version I have.

 

you need a new 12v. if a jump pack didn't work, and you know the pack is good (which you may not, since you seem to think 11.5v is not worth doing something about)

try taking the 12v neg off and jump directly to the cables

 

the voltage is high enough, maybe it’s the starter. Are you able to locate the starter in the engine compartment?

 

Yeah don’t answer this, lol.

 

If there are warning lights and/or "check hybrid system" messages on the dash, then the car wants to tell you what the trouble is. Getting the trouble codes would be a much more productive path toward the solution than all of this thrashing.

 

what thrashing?

 

the 12v makes the car 'ready'. did the ready light come on? stop focusing on the engine, the 12v does not start it, but completes a necessary process so that the hybrid battery (if capable) can turn the engine over.

 

Well I am certainly not an expert. But as I understand the process, the 12 volt battery Boot's the start up process, computers and the computers (or whatever) start the High Volt Battery and that starts the engine?

It sounds like your repair of the High Voltage Battery did not take (for long)? If you drove it for a few day's and it was not charging the HV battery? Most likely the high voltage battery is flat now?

 

wack o mole stage 1 completed.
