My service 4wd light has been going on occasionally for a couple years now, and of course dealer has no idea why. I was thinking it may be one of the abs sensors, as it used to only come on while accelerating from a stop and turning left (odd), so I bought new front ones. Replaced them last weekend, now service light comes on almost every time I start the truck. No ABS light though....

2 questions, is there an affordable way to read the codes triggering the service 4wd light? The reader I've found is close to 500 I think.

Also, I broke the plug on the harness side of the driver front abs, is it replaceable?? I currently have it zip tied together LOL

Thanks guys!
