There is also software included in the recall that allows the vehicle to ignore up to 3 of the redundant temp sensors if they fail, rather than having to replace them. Oh and one more thing, the 2013-2015 volts have 9 battery temp sensors but really only need 6. Complete discharge/complete charge cycles will accelerate this learning process. This is also why some people have seen the change quickly and some it took a while. This is why some people noticed almost no change and others have had a change in the GOM. If your cell balance was off, the more it's going to change after the recall. If yours was one that was close to correct, not much will change after the recall. Even with the bad software some vehicles were staying close to properly balanced and others were quite a bit off. Also not all vehicles have the same cell imbalance. This process happens much slower without full discharge/charge cycles and so some people the adjustments happen much quicker than others. If your GOM goes up or down it means that the car had not been properly balancing the cells for quite some time. Over the course of multiple charge/discharge cycles the cells properly balance, and then the module relearns the capacity and the GOM adjusts accordingly. The vehicle starts to properly balancing the cells again, and the battery capacity learned values are reset. When they reprogram the module 2 things happen. The balance of those cells is part of what is used to calculate the GOM. The recall (GM Program #:N172130462 Issued:Mar 28, 2019) is to correct your vehicle from improperly balancing the cells over time. The VCX Nano and ACDelco subscription that allows you to program it is the only way to clear it.Ĭlick to expand.Jaryd Carvell->Hi friendly neighborhood volt tech here! As I have tried to explain to so many people in this group. The DTC it throws is a "permanent" code, so a normal code reader (or HPTuners) won't be able to clear it completely, just enough to let you charge it once or twice before it pops back up. Have you checked the battery coolant level yet? The fluid level getting low, the battery coolant sensor going bad, or the wiring from the sensor to the PCM getting damaged are the most common reasons for the SHVCS message popping up. Apparently the BECM also needed to be reprogrammed, so I hooked the VCX Nano back up, reprogrammed the BECM, cleared codes, reprogrammed the HPCM, cleared codes, and the message hasn't come back in a week so far. SHVCS message still showed up after that, back to google. After doing some google-fu, I ordered the battery coolant defeat sensor, installed it, purchased a VCX Nano for $125, an ACDelco TDS subscription for my VIN for $40 and reprogrammed the HPCM/cleared the permanent codes afterward. The SHVCS message would pop up, I'd clear the codes with my HPTuners (usually 3 of them, P1 something or other), car would charge fine and the message would come back up again. I think the suppliers furnish refurb batteries. I really don't think you can replace the traction batteries with a new battery. However, if for some reason, there is a problem with the traction battery, I am not willing to spend that kind of money to keep it going. I have another 2013 Volt that I bought brand new, and it has about the same mileage. There is another dealership that works on Volts here, so I am debating taking it to them and see what they say. I told him I'll just pick the car up tomorrow and just charge me the diagnostic fee ($140). He quoted me $11,000 to replace the battery. In order to further diagnose it, they looking at close to $800 to check the charging cord to feed the battery and if not, then it's most likely the traction battery. Well, the service manager said that there technician thinks it's either the charging cord feeding the battery or the traction battery itself. Now, I decided to take it to a dealership here where I live to see what there diagnostic say. So, on the occasion when it generates the code, I just reset it. When it does generate that code and I am still driving on battery, it drives fine and when it transitions to engine, it drives fine. The car fully charges, usually around the 38 - 40 mile range and when I drive it, it usually goes that far on battery. I can reset the code and every thing is fine for awhile. I have a scanner and the most it would say is a P1E00 code. In the last two weeks, it has been generating a "Service High Voltage Charging System". It now has 93k miles and the warranty expired earlier this year. I bought it used six years ago and it had 15k miles on it.
