Pulling Dodge B-2500 RABS DTCs Q. Hi, I asked a few days ago in the forum but got no response. My 1996 Dodge B2500 3.9 liter V-6 has rear antilock brakes only. The RABS light has been coming on and I wanted to check the codes rather than the "shotgun" approach. I found the module under the glove box but there is no pigtail to ground to get the code flash.

Have a Haynes manual but it is wrong as the control valve is located on the main hydraulic block under the master cylinder and not on the frame. It has OBD-II but my OTC 4000E doesn't support ABS on this vehicle. In the past year I had to replace all the brakes, calipers, wheel cylinders and steel lines. There are no problems or leaks in the brake system.

I suspect it is the rear end sensor as the light will only come on when the vehicle starts moving and will go out when reset with ignition switch. I really just need to know how to retrieve the codes on this thing. I am a 33 year retired Ford mechanic so I have some idea what's going on.

Thanks much,
Chuck

A. Sorry Chuck. Chrysler only provides a procedure to pull ABS Codes with a Chrysler Diagnostic Readout Box (DRB) scan tool. There are no procedures provided by Chrysler to pull ABS codes with a generic scan tool or any other procedure besides using the Chrysler DRB.
