Hello everyone, a few days ago I was on my way to vacation when my 2006 5 spd had the battery light come on briefly, then the IMA light flashed a few times before staying on for a few miles, then the battery light flashed again and the car started driving weird, I pulled over at a crossroads in rural NC where I turned off the car to check under the hood to make sure nothing looked weird. Everything under the hood looked good so I started the car and drove about 20 feet where the car sputtered and died. One of the relays in the IMA battery was clicking like crazy when the car was off, I've attached a photo of my pointing on that relay. I figured the IMA died despite some of the symptoms not lining up, I disconnected the IMA via the 2 connectors in the battery and reset the IMA by pulling the 30a fuse under the hood. The car started on the 12v starter and ran for about 30 seconds before stalling out. After that nothing I could do would get the car to crank. Waited 4 hours for a tow home (thanks AAA) and continued about on my vacation with another car.
Getting back home to work on the car I jumped the OBD 2 port and got the following codes flashed at me:
EPS: 22 and 23
ABS: 61 and 81
IMA light was steadily lit on the dash but did not flash any codes.
Used my code reader and got a P0A64 and P1430 stored codes but the light was not on while driving.
Looking on this forum the EPS and ABS codes seem to me to all relate to 12v issues and wheel sensor issues that might have occurred in the past and the code reader stored codes also all seem to be unrelated but could just be from when I was unplugging and plugging the 2 connectors into the controller.
In trying to do some diagnosis, the immobilizer seems to work (green light goes off when trying to start). I charged/discharged/charged/discharged/and charged the IMA with a grid charger over a few days, reset the IMA with the 30a fuse to no avail, and also disconnected/reconnected the battery to no avail. After doing some more looking on here I checked the grounds, the one near the trans mount looks good but the 2 next to the airbox were pretty corroded which might be an issue?
I should note the car had a coolant leak along the water housing at the end of the head which I fixed recently and the car ran great for about an hour losing no coolant before encountering the above issues. I've tried to wrap my head around this for a few days but I just can't figure it out and information I found looking into the P1430 code looks way over my head.
Any help would be greatly appreciated! Thank you!
