My trucks 4wd wasn't working and I replaced every single part related to the 4wd actuation with no luck. Last thing I was gonna throw money at was the Module because it'd usually be the priciest before actually getting into the transfer case n the like. Thankfully I found this transfer case control module and the ad said it worked. Low and behold, I remove the old one and install the replacement and 5 minutes later I have a fully working 4wd and no more dash lights like stabilitrak and ABS. Thanks again!
