Have a short somewhere on my HS CAN circuit, I have unplugged the ABS module to see if this is a fix, I have no CAN, I use the SDD software and it wont see anything, tested the resistance it is 120 ohms. Which modules should I be unplugging to isolate this? I bought a CJB and put in, nothing changes. This is on a 2017 F Type 3.0L X152.

 

If i remember correctly, total resistance should be 60 ohms, not 120. There is a break in your CAN somewhere. Do you have a picture of which module are offline via SDD? There is multiple CAN in vehicle.

 

via the SDD all modules are offline. Yes you are this particular car has dual CAN, this is on the HS CAN I believe the resistors are 120ohm each and are in the CJB and the ECU. Just hoping that someone has had similar issues and knows where the best spot to troubleshoot start is.

 

Resolution was seat modules need to be connected for can voltage to pass.
