That dotted-line square you see in the diagram indicates that all these components are inside a relay. A relay is a type of switch that works magnetically. The magnetic part involves passing current through a coil to turn the switch on or off. So the coil is inside the relay. Look up how relays...

I haven't followed this thread from the beginning, but the data posted here is interesting to follow and relate to my 2016. So, what is the source of the Kwh, and mi measures posted here? If it's TorquePro, which PIDs do you use? (FYI, MyGreenVolt is another app I've used that seems to work...

That's disappointing, I was hoping the Bolt would be a little more efficient than that, even on hwy usage. Every friend here with a full range EV (Niro, Tesla, ID4) and stock tires gets really low mileage compared to the Spark EV.

I've seen some of that type of behavior on mine also. I haven't tracked this in terms of the GOM range estimate but specifically only to the drive cycle efficiency shown at the end of every trip. The same exact in-town route on different days with identical mild weather (mid 60s-mid 70s), with...

I really appreciate this insight, but I haven't been able to find more information from the CA DMV. I drive a 2016 which I bought used, and it already has white stickers, which I was told may no longer be valid for HOV use. I assumed the stickers on EVs were already on when the cars are bought...

I agree with NORTON. My approach would be to first check the surface voltage with a multimeter. Then trickle charge it. Ideally it should read 12.6 v. Then see if the car turns on note the SOC for reference. Then go ahead and charge the high voltage battery. Also, depending on how long your...

I just started playing with the Bold PIDs in TorquePro and monitored a few of them while charging the car from about 25% to full. Module 3 seems to run about 3-5 degrees F hotter than the other ones by the end of a charge cycle. Is this variation within acceptable range? Module 1: 57.2 > 66.2...

Thank you for sharing this.

If you didn't get the service records from the previous owner, check for a round date sticker on the 12V battery. It will indicate its vintage. Knowing that date won't reliably tell you if the battery is good or not. 12V batteries need to be tested with a load tester. Check with your local parts...

Good catch. Curiously, the GM parts catalog lists the same part number 95260968 for both the gas and EV version of the Spark: 2015 Spark GAS 2016 Spark EV

Thanks NORTON, I'll do just that. I thought about cutting out a plexiglass mirror too. It wouldn't work in my case. The part of the housing behind the mirror tray has deformed and would still interfere with the mirror tilt. FYI, you can buy a mirror replacement if that is all you need. Read on...

Hi folks, Is it true that the 2016 EV uses the same parts it has in common with the 2015 Spark (gas) vehicle? I have seen this mentioned a few times here, and it looks like I am getting an intro into the GM parts catalog ecosystem hell. Long story short, the RH mirror housing had a deformation...

Thank you, yes, I read about the 3G going away in another thread (maybe a post by you). I am assuming there are a few basic functions that rely on onStar in some way regardless of subscription status. (maybe the center console uses it to synch the time?) I found this...

I am guessing the previous owner had onStar and set up a wifi hotspot. I finally figured out how to get the wifi password. I went to the gateway IP hoping there may be a EWS that would let me inspect/change the wifi config ... no dice. Has anyone found a way to hack into this and use their own...

Hmmm, I am relatively new here but I am using the term GOM to describe the range min and max on the battery bars on the left. I am a fairly clear on the trip mileage (miles/kWh), and generally I am not surprised by those -- they seem to be actuals, rather than estimates. FWIW, with my driving...

Reading about how preconditioning may draw power from both the EVSE and HV battery, I am wondering if that plays a role in how the GOM estimates range after a full charge. In the summer a full charge showed a range estimate of 95-105 (which I take with a grain of salt). Since we started using...

I can confirm the same. We rarely need to use HVAC while driving. It only gets used during preconditioning (which IIRC runs for up to 20-25 min) and without the need to have it on before shutting off the car. And yes, it never makes the cabin hot enough, just warm-ish. I'd prefer that it stops...

Thank you. I really appreciate the detailed explanation.

I am hoping someone knows more about the electrical characteristics of the onboard HVAC systems and perhaps explain how they get powered under various scenarios (plugged in and charging, plugged in and fully charged, during regen). Q1: If the car is plugged into a L2 EVSE, does remote...

Thank you, that explanation makes perfect sense.
