Techstream alternative full#

Several of the ones I see online are full service and I know there are shoddy rebuilds out there. I would want to change the battery pack myself, so if that is the prognosis, current recommendations on rebuilt battery vendors is appreciated. Now my son is driving it daily, thus I need to get it working properly. The rest of the time it sits parked, not good for the battery I know. Only other pertinent info would be that the last 2 years, I have driven this car to the airport weekly, about 10 miles each way and maybe 10-20 miles on the weekend. Is that a thing? Would there be codes or a diagnostic I could perform to verify a healthy inverter? Another option is that this episode accelerated the death of a sick battery, however it would be good to confirm the inverter is working properly in any scenario. So, my only alternative theory to a dead battery would be a crippled inverter that isnвЂ™t dead, but isnвЂ™t charging sufficiently. My wife drove it like that for a week or two on some hot days. In hindsight, this was when the inverter overheated.

This car cries wolf so much, I didnвЂ™t jump right on it, assuming the red triangle was the 12v battery again as it would come on intermittently. The only reason I hesitate with a dying battery diagnosis is that this summer my inverter coolant pump died. I am aware of the meaning of these codes and the mileage is down in the 30s, so classic dying battery symptoms.

OBD2 couldnвЂ™t read code, so I finally bought an XP laptop and TechStream (i have used it in the past). No active codes, but it has been red triangling me off and on over the last month or so. I believe this second one is failing, but would like someone to double check my work before I replace. I am on the second HV battery, changed at 100K.
