natesoony · April 14, 2015

Hi I have an extended cab long bed 6.0 2500 (non hd) I dont know if that makes a difference or not but a couple months ago I slid off into the ditch and hit my front end and slightly bent the frame well my buddy is straightining it for free so when I went to put the truck kn the trailer cause the radiator it cracks I put it in 4x4 to climb on the trailer and all it did was sat there and blinked I couldn't tell if the actuator was wprking either I figure I ****ed up something so im looking along the lines of a sas unless someone can enlighten me on how to fix this

If you do have to buy a code scanner, you might consider buying a higher-end one, like an Autel MD802 [i happen to have picked one up on sale for about $300 CDN]. It not only show basic ODB II codes, but it also displays [and stores so you can download them on your computer] live data for your engine and transmission [and probably also your transfer case], air bag codes and ABS codes. And it supports a bunch of NA, european and asian cars, and Autel puts out updates for it for news vehicles. I found it really useful for figuring out what was going wrong with my '04 Sierra 3500 w 6.0L gas motor.

The only thing that is stupid about the setup is that Autel STILL hasn't updated their computer software to have a signed windows driver [needed to work seemlessly with Win [7 possibly] 8 and newer]. You have to disable the windows check for signed drivers for the software to work.

Any luck on getting your truck scanned and getting codes. I have the identical model truck and on mine it was the dash switch, but that was a wild guess since the lights weren't even come on, on the switch.
