Got a 2002 Dodge Dakota 4.7 and all of a sudden the abs and brake light on dash come on. Brakes are fine parking brake works and is not stuck,then noticed the speedo doesn't work and the cruise also doesn't work. Checked the fuses fine, brake fluid fine, and disconnected the battery for about 10 min thinking it might clear but it didn't. Ok guys where to look for the problem I'm not that good on the modern stuff so I really need some help. Probably simple to some. I really appreciate al the help I can get. Thks Garymac

check the abs module. they're known for having bad connectors, that get water inside them, and cause all sorts of mischief. the rear axle speed sensor could also be bad. it's about five hundred bucks cheaper than the abs module (located behind the battery) the speed sensor would signal the speedo, cruise, etc. the abs problem might be solved by opening, cleaning, lubing and reconnecting the abs module.

If you spot a wire harness going into a sensor in upper differential, that may be clipped to brake hose or diff vent hose, that sensor would be suspect.
That used to be the case with RWAL. With the newer ABS systems input is given from both front wheels as well as the rear axle sensor. I would get the ABS system and other systems scanned for codes.

yes, the locks get a signal at 15mph (from the speed sensor) and lock. if you cleaned the connection, and it doesnt work, you need to test it, and/or replace it. the sensor is about 50 bucks. chasing the wires, all the way to the ecu, is free for you to do, though. pull apart each connector along the way, and clean out, spray with tuner cleaner, etc. i'm doing the front abs sensors on my '02 pt cruiser this week. they are bad, and the abs light, brake light and trac light all came on. tested the computer, and it's throwing codes for the front l/r abs sensors. get a scanning tool, and have at it.

Your truck came standard with RWAL. 4-wheel ABS was an option. Which system do you have? Post a pic of your inner fender if you don't know which system you have.
That said, the symptoms you described is spot on for a faulty speed sensor located in the top of the rear differential. It's about $20 at your local parts store and probably in stock.
If you wanted to pull the codes first to 'troubleshoot' the problem, the dealer has the scan tool to access the abs codes. The scanners used at parts stores can only read emissions codes. But the dealer will want $100 just to plug in the scan tool.
