    Spark ev died while driving!

    After driving the car around for the week and watching how the batteries behave its definitely a case of the 2 cells being damaged. They hold steady with the rest of the pack until around 30% where they lose voltage fast. We're going to continue using the car with the mindset that 50% is 0% just...

    Got back from work and checked the cells. They have self-balanced. I'll drive the car tomorrow and see if they discharge the same way.

    Update. Didn't have to do the test. Just reprogrammed the HPCM2 and then plugged it in. The car is now charging. I'll check on it after work to see if the 2 weak cells balance or if they are damaged.

    I found a volt owner that had the same problem, he ran a isolation test to get the car charging. How do I run an isolation test on SPS2?

    Ok so I got the nano to work and I am connected to the spark in SPS2. What module would I have to reprogram to get the car charging?

    On what you said about the shut off being around 2.5v I agree because I was talking to my friend with a 500e who said his battery went down to 2.6v and was just fine. That's why I'm thinking that 2.9v isn't the problem, but more the imbalance that shut the car off. We had multiple 500e's revived...

    Scanning app

    Sorry my mind blanked when making this, TorquePro with the bolt PIDs does the trick. And Infinion said the VX-NANO will do the trick for deeper codes. I forgot he said this. My bad lol

    Spark ev died while driving!

    I got the readings from TorquePro. I read on the bolt forums that they have PIDs that they download onto the app to read the cars computer. Those PIDs work with out sparks. As for the HV battery, no its not toast. The car has bricked itself because 2 cells are out of balance once those cells are...

    I'll use the VX-NANO like Infinion suggested

    Ok I found my problem. Cells #49 and #81 seem to be too low

    Scanning app

    Does anyone know an app I can use to scan the car and see the cell voltage? My green volt isn't working and I need an alternative

    i also have this code. According to the volt forums this means low battery voltage

    Spark ev died while driving!

    Is there an app that allows me to scan the car more indepth? With my 500e i was able to analyze everything. I want to scan the cell voltage for the batteries to rule out the batteries being the issue. If they arnt my main suspension is still the BPCM

    It's 100% not the 12v battery. I bought a new one and Unfortunately nothing changed. I've been able to read some codes and P1E00 is the only code that stays.

    At 8 minutes in the video he says gm replaced a computer and the cells. I dont think my cells are bad because around 2 weeks ago I took it about 45 miles away at highway speed. Certainly not like new but I don't believe the cells are bad enough to kill the car. Thoughts?

    Spark ev died while driving!

    I called my local chevy and they said it expired in April. I'll double check the door jam. From what I've read from the forums "Infinion" referred to, all of those seem to be 12v failures. My 12v is a a battery shop being charged but my suspicion is that it's worse. It's a flooded battery so no...

    Thank you for the reply. The car was on the side of the road so I took the 12v out and took it to autozone to get tested. And the guy said it has 93% SOC. I dont believe it's the original battery it's a Napa "the legend" battery from 2022 according to its sticker. I'll start reading and playing...

    I want to add. I have my fair share of experience with these compliance cars. I have a fiat 500e that had the same warning and wouldn't drive. That ended up being caused by the BPCM. Is there any software I can get to start scanning the car?

    Hello everyone. We recently purchased a 2016 spark ev about a month ago. It was working great until today. We were driving along and it had 10 miles left. Than it suddenly went out of ready mode and came to a stop. Now the car says it has a full battery with 3 miles of range. The exclamation...
