TCS No Comm.

Hi Folks, so for the last 6 months I haven't been having any trouble with my TCS... OK thats a lie, i've seen the steering sensor code pop up once, but i wiggled the connector on the column and that code hasn't came up since.

So last night, i swapped out my spark plugs and wires. The car ran great all day, and the next morning. Then just tonight - i get in my car and start it, and when i pull forward my TC and ABS lights come on and the Service Vehicle Soon message activates. Sure enough my TCS says "NO COMM" and some other codes i've never seen before pop up too...

P1644
B0844
U1040

The only electrical thing i changed yesterday was disconnect and reconnecting the negative battery cable.

Any ideas on what my problem is, because a new TC Module is about $1200...

Where are the TCS Plugs, grounds and fuses i should check?

Thanks,

Dan

I had a similar issue with mine....TCS-No Comm...but with different codes. Mine turned out to be a blown #53 fuse in the underhood fuse box. Check those fuses and good luck!

I saw someone else on the forum have this problem and they fixed it by reconnecting their negative battery cable...

So i tightened mine down (turns out it wasn't very tight) and the problem has went away... lol

Thanks for the replies... though
