I have a 97 XJ6 and am wondering if there are both an ECM and a TCM or are they both one unit. Any help would be appreciated.

Thanks

 

To the best of my knowledge, and terminology I have heard over many years:

TCM, is for Transmission Control Module.
ECM, is for Electonic Control Module, OR, Engine Control Module, depending on language spoken, and understanding of said language. We Stralians do call things diffeerent to others I believe.

Electronic Control Module could be any module on any car controlling any component, mmmm.
Engine Control Module is quite specific, no matter what badge is on the car.
Transmission Control Module is again, quite specific.

 

Ok. I've attachted jpg files containing what I'm seeing as the TCM and ECM. I've located the TCM, it was pretty easy right under the glove box. Can anyone tell me where the ECM is located?

I goofed and bought a new TCM thinking it was the ECM.

Thanks in advance for any help,
Pat

 

ECM is located in the trunk, remove the panel that covers the battery, then ECM can be found under the black plastic cover housing the trunk fuse panel.
