So I went out today to start the 2010 LR2 and it had a dead battery...havent been having any issues lately so I got it jump started per the manual but it shows a code of P0700 for the TCM Transmission Control Module. Everything else checks out and it seems to be charging fine at 13.8V. I am wondering where is the TCM located? I could here maybe a relay clicking in the center console when I was trying to start it. I did some research and it said it could be on the trans the firewall or in the center console. Is there any way to find out for sure without taking things all apart? I Usually don't drive it much just very short trips as I work from home so it doesn't really see any distance to get the batt charged up all the time. I pulled the battery and its on a charger now to get it back up to peak charge. I'm just looking at options as to what it might be so I wanted to check connections at the TCM before I go any further. Any help would be appreicated.

Thanks

JC

 

False codes are often set when the battery is low so I would fully charge it, copy down the code, then clear it and see if it comes back as a first step.

 

I pulled the battery out and charged it over night and then re-installed it and no codes. I went back in with my scanner just to double check but nothing was active so I cleared the historic faults. Someone else mentioned that LR's are voltage sensitive so I think I'll get a battery tender for it as I don't drive it much and when I do its not for very long. Thanks for the reply I appreciate it.
