Now, I need to compare to something else, do you have the schematic for Jeep 2014 with the NQH MP3023? With the TCCM number 68395074AA

looking for schematic for 4 high/low switch, TCCM controller and wiring harness from the switch to the TCCM and T-case.

Thanks!

Hello, what size engine do you have in this vehicle? It's odd, I can see that's the Transfer Case control module for a 2014 Grand Cherokee after doing a part number search but am not finding it under any engine size in our service info.
And it looks like the Transfer case selector switch communicates its data out on the Lin Bus network wire, and the Shift Lever assembly module communicates with the Transmission control module on a 2 wire Data Bus and the Can C bus network.

But there is no listing for a part number for the transfer case control module. The one you have is correct, it's just not listed in service data for some reason.

Thanks for helping.

You are correct, it seems that the communication is transferred through the cluster in some way.

Do you have the schematic between the dash cluster, Dtcm, switch, tcm ecm bcm etc. So I can check all the way where the Lin and can bus are going. Thanks again

Okay, so you want a diagram of the entire communications network of the vehicle? Or do you need something more specific? I'll pull up the network topology diagrams first.
There is nothing listed under either of those vin numbers, what size engine is in it, V6 3.0 dsl turbo, V6 3.6L, V8 5.7L, or V8 6.4L?

This is for the 3.6L, but it is exactly the same as the V8 5.7. Every 2 pages go together, pages 1 is the top and page 2 is the bottom of each diagram. This is the entire network, canbus, Linbus, etc.

These are the ones I need.

Do you have the schematic between the dash cluster, Dtcm/tccm, 4wd/4lo switch, tcm ecm bcm etc. So I can check all the way where the Lin and can bus are going.

Thanks again.
