Status on Cars 1, 2, 3

These cars are sooo close, and yet still not there.

My keeper was driving beautifully with its rebuilt battery, and then started throwing battery codes. Discussed in another thread.

My son's car has been giving me a triangle/CEL but my ScanGauge is not picking up any codes. Otherwise, it seems to run fine, battery 300+V, SOC 60+%, temps good. I thought the inverter pump might not be working. Fluid didn't seem to be churning in the reservoir. When I got the bumper off, I saw that it was the newer version, turned the key, and it's working fine. Drove it around some, and after clearing the CEL 2-3 times with my reader, it has stayed off for about 10 miles of driving. But, it's done this before, and the CEL came back. I've ordered a VCI cable, and it's shipped. Still need to scavenge an XP laptop and labor through the install.

The third car I'm currently working on is also seemingly running fine, but it throws a 3030 code, over and over, as fast as I clear it. I replaced the buss bar harness with sensors, but not the opposite side. Hopefully, when I get TIS operating, I can identify where the problem is.

Misc: the door locks don't work on one car, I can't document the details, whether it's lock or unlock or both, all doors, which doors. But it's almost all that stuff. I remember seeing only the passenger front door "try" to lock, none of the others moved. But, that would seem to suggest the arm rest control module is all connected. The Windows work. Any tips on where to look for the problem?

 

Thanks. A door motor shouldn't be too hard. And my parts cars have plenty of those. As long as it's not riveted to the door like they do with the window motors some time.

 

It's not using the rivet gun, you just use bolts and nuts to put it back together. It's grinding the rivet off that's hard work, or at least it is if you don't have a grinder and try to beat it off with a chisel.

 

UPDATE:

I received the warranty eplacement battery. I put the original in my keeper car and it ran perfect until the battery hiccupped. I decided to put this replacement today into my car that's throwing the 3030 code, to see if that would clear the code, and it did. I still have the 3rd car, the one throwing a CEL, but no code coming up on my SG and it seems to run fine. I could swap the new battery into it to confirm it doesn't have a battery issue, but manhandling these batteries in and out by myself is hard work. My back is barking tonight.

Instead, I'd love to just diagnose what's wrong with this battery that I took out (it's not the failed core I have to return to the vender, that's still in the keeper car to be removed tomorrow). If I can fix it, without having to install it in the keeper car, scan it with TIS, take it out, fix it, and put it back in, I'd sure save a lot of work.

Again, it is in the battery, nothing on the car is causing the issue. I used a handheld voltmeter to test each cell, forget the details, but almost all were just fine. I swapped in some stronger cells from my first core, then another module to replace one with a stripped buss stud. Should have been a strong set of nearly balanced cells. Then, I put a new OEM buss bar harness with sensors on, but I left the back side buss bar in place after removing and cleaning it up.

BTW, based on the discussions I see here this battery is either a replacement or from Canada or both? It has 3 large labels on the top, covering most of the visible area.

Since the 3030 code is a wiring issue (?), where are the possible locations on the battery that could be grounding out? I didn't examine the power supply(?) or ECU closely when I was swapping those modules and buss bar. Is it likely that the back side bass bar would break? It seems so basic.

I expect that the correct answer to my questions is to get TIS - I'm working on that. Have my cable, trying to scrounge up an XP laptop but not having much CraigsList luck. Has anyone run TIS on a virtual XP machine? Would that defeat the purpose of using a separate laptop from a security perspective? I am low-tech, my current laptop runs Windows 7 Home. As I look at old XP laptops on Ebay, etc, I doubt any of them have battery life left, if you could even find new ones, they probably cost as much as the PC. I hat to have to run an extension cord out to the truck to keep the XP running while I diagnose the car. Doesn't let you run see live data while driving.

But, if I get TIS going, how would I use it, if at all, to figure out what's wrong with this battery? I assume it will alert me to any module pair with low voltage, and I'd then look at those cells for wiring issues, or replacement. Would it point me to any of the other battery components? Are there any tests I can do without TIS? I have the battery out of the car right now. I feel like I should pop the top anyway just to have a look around and put the voltmeter on the cells again. Or anything else while it's out.

I'd even have to think twice before not swapping in a power supply and ECU right now, rather than put this one I know is broken into the car again to run TIS. Only problem is I'd probably get those from my parts car's battery, which still means taking a battery out (save a couple of steps anyway) with the risk that those parts are no good either, with no way of knowing. Crazy stuff, hard decisions, but only because I'm a weak old man.

 

Sorry, I shouldn't have said that. I'm ignorant about electronics and just used that as a general term for "broken."

Since all the sensor wires are brand new, part of the new harness, I hoped that eliminated any such issues. But, I'll look over them again. Was hoping someone knew of other places I might have bad wiring inside the battery. Thanks.

 

Yeah, my old ScanGauge works fine for most stuff, and I have a TP/BT setup as well, but neither of those are reading the DTC being thrown by one of my cars. I also need to figure out what's wrong with the HV battery in another one - I'm getting a 3030 from inside the HV battery, but I've replaced the sensor harness and the cells are all charged. Does TP read the voltage for individual modules? SG will, I think, with the right Xprograms, but I don't have room to add any more. I'll look up Virtualbox, thanks.
