Hi,

I attached the wiring schematic below for the AWD circuit. I highlighted two fuses I need you to check first. I highlighted them in pic 1. For some reason, my manual isn't showing me the location of the fuses, so I need you to check under the fuse box cover for a legend or in the owner's manual.

Now, in addition to checking the fuse, I need you to confirm there is power to and from the fuse. Here is a link that you may find helpful:

If the fuses are good, we will need to scan the can-bus system. CAN stands for controller area network. Basically, all the modules are tied together and communicate via this network. When you scan the can-bus, it will identify diagnostic trouble codes regardless of the module that recorded them. If it isn't done, it becomes a guessing game. Here is a video showing how it's done:

If you need to have it scanned, record the code and let me know what they are.

Let me know what you find.

Take care,

Joe
