Is this the ECM? Or the TCM?
Hey all
im getting a u0101 code no speedo.. Im thinking the TCM is bad.. 2005 vue 2.2 Is the tcm and ecm same unit? I google both and ssme pics come up I see a module on the engine https://cimg6.ibsrv.net/gimg/www.sat...397fb0fd7b.jpg And another search says its near steer ing column on interior https://cimg2.ibsrv.net/gimg/www.sat...474a19f6a3.pngThis is inside vehicle.. so which module is it? Thanks in advance |
Take a picture of your engine please. The first picture shows a pcm of some sort that I do not recognise. Thanks |
Don’t you just love one and done. The picture is of the pcm similar to what runs a both the engine and trans in an L200. Does your Vue have a 4t40? Who knows? I don’t. I though the Vues had a 5 speed automatic of some kind. |
So the L's had a PCM and BCM but no standalone TCM? I just woke up literally 3 min ago but I I always assumed that once someone went to the trouble of separating out the BCM functionality from a PCM, they'd do the same for the TCM at the same time.
Though I suppose if the computing power was still available in the PCM, it would be more efficient to keep TCM commands inside the same module...... |
The 2.2 cars have a pcm that controls both, the 3.0 cars have an ecm and a tcm. I think they did that since the 3.0 is an Opel engine from the 90s and the 2.2 is newer technology. |
