Hi, I recently took my car to get a custom roll cage installed and after the installation the AWC switch stopped working and i also get a service required DIFF malfunction on the display.

The only thing that was removed during the cage install was the SRS ECU.

I'm pretty sure the front diff is not working because i'm spinning the front right tire on right hand corners.

I have tried to read any DTC's using the Accessport and LM-2 but have not found any.

Does anyone have any experience with this issue?

Any feedback would be appreciated.

Thanks.

 

You either blew a fuse or shorted the entire system. Did you leave the battery hooked up when welding?

 

Battery was unhooked for welding.

Any idea what fuse is responsible for the AWC?

 

i think its chapter 7 in the owners manual for fuses
