Hi, I have a 2wd 95 ranger, recently the abs light has come on while driving. There has been no brake problems, still works perfect. Recently filled the brake fluid, didn’t fix it. was wondering if anyone new what it might be.

Since you have 2wd, you have the RABS system. Here's some info on it.


The RABS module performs system tests and self-tests during startup and normal operation. The valve, sensor and fluid level circuits are monitored for proper operation. If a fault is found, the RABS will be deactivated and the REAR ANTI LOCK light will be lit until the ignition is turned OFF. When the light is lit, the diagnostic flashout code may be obtained. Under normal operation, the light will stay on for about 2 seconds while the ignition switch is in the ON position and will go out shortly after. A flash code may be obtained only when the yellow light is ON. Before reading the code, drive the vehicle to a level area and place the shift lever in the PARK or NEUTRAL position. Keep the vehicle ignition ON.


Starting in 1993, all vehicles use the RABS II system. The major difference between the two systems is the addition of keep alive memory (codes are stored, even if ignition is turned off), and a code 16 can be set which means the system is operating properly.


TO OBTAIN THE FLASH CODE:


  1. Locate the RABS diagnostic connector (orange/black wire) and attach a jumper wire to it and momentarily (1 to 2 seconds) ground it to the chassis.
  2. Quickly remove the ground. When the ground is made and then removed, the RABS light will begin to flash.
  3. The code consists of a number of short flashes and ends with a long flash. Count the short flashes and include the following long flash in the count to obtain the code number. Example 3 short flashes and one long flash indicated Code No. 4. The code will continue until the ignition is turned OFF. Refer to the flashcode diagnosis charts for further instructions.

Here is a location description of the components. I was looking for a description of the location of the code testing wire, but the description and the attached picture don't seem to jive.


The RABS consists of the following components:

  1. RABS module-located in the dash under the instrument panel mount on a brace, center of panel area.
  2. Dual Solenoid Electro-Hydraulic Valve is located 5 in. (127mm) rearward of the No. 1 crossmember on the inboard side of the LH frame rail.
  3. Speed Sensor and Exciter Ring-located in the rear differential housing.
  4. Yellow REAR ANTI-LOCK Warning Light-located in the instrument cluster.
  5. RABS Diagnostic Connector (1991-96)-located on the main wire bundle inside of cab under the dash, slightly rearward driver side.
  6. RABS Diagnostic Connector (1997)-located on the forward end of the power distribution box, under the hood.
  7. Diode/Resistor Element (1991-96)-located three inches left of the cluster connector takeouts in the instrument panel wiring harness.
  8. Diode/Resistor Element (1997)-located in the power distribution box, under the hood.
  9. Sensor test Connector-located under the hood slightly rearward the washer bottle.
