All of a sudden my ABS light went on and a few minutes later the CE light came on, and then a few minutes after that my OD light started blinking. Tranny started shifting funny, speedo quit, cruise control quit. Man, I thought the whole Bronco was crapping out on me!! I took it to my local mechanic and after a while he called me and asked if I had pulled a trailer in the past few days. I had. He said the trailer lights must have had a short and blown the fuse and that fuse caused all of my problems. Hard to imagine.

4WABS Control Module Overview; "...A new light truck 4-Wheel ABS was introduced as standard equipment on the 1993 Explorer and Bronco, and it was revised in 1994 on Broncos, requiring a different control module revision for 94-96 Broncos, compared to the original '93 Bronco module. The anti-lock brake electronic control module is located in the engine compartment behind the driver's side head lamp on a bracket mounted on the surface of the plastic fender apron. It is an on-board diagnostic, non-repairable unit consisting of two microprocessors and the necessary circuitry for their operation. These microprocessors are programmed identically. The anti-lock brake electronic control module monitors system operation during normal driving as well as during anti-lock braking. In addition, the anti-lock brake electronic control module provides a speed signal to the programmable speedometer/odometer module (PSOM)..." read more

Wow, thanks Miesk5 for all that info. I'm sending it to my mechanic. We only have 2 auto mechanics in Garden Valley so I am sure he will enjoy the read. I really appreciate it that you took the time to respond.

yw Pappy.
Was a Scan done for DTCs?
Also print is out here; in case the fuses are good.

This stuff;
There are abour 4 connectors from the ABS Sensor on the 8.8 thru the 4WABS Control Module & then up to da PSOM (Speedo/odometer) and then to the EEC/Cruise Control/ Overhead Console.

Is the Amber ABS Light lit all da time?
some tips;

PSOM Continuity Test Through 4WABS Control Module Connector in 93-96; "...jumper 14 to 21, & 39 to 22..." MIESK5 NOTE; See diagram. I did this on our 96; The 4WABS Control Module was toasted; 2 yard 4WABS Control Modules were also bad; NO RETURNS!

He jumps out the 2 wires from the VSS Sensor to the PSOM and beyond... so it jumps the ckt thru the 4WABS Module instead of going thru the Module in order to discount the module if it's bad, which it was in my 96.

Tone Ring Inspection; "Take off the rear diff cover. Check the Ring Tone gear. It is located on the left hand side of the ring gear. Look to see if any of the teeth have been notched (from debris floating around in the diff.) Usually a spider gear. If the ring tone gear has been notched, it will need to be replaced to fix your speedo reading. Jack it up and rotate the tires to look for the teeth to be notched/broken/bent..."

Pointer Waiver TSB 96-21-11 for 92-96; "...The speedometer needle may waver and/or a light surge may occur on some vehicles when speed control is used at highway speeds between 80-113 km/h (50-70 mph). This may be due to slight dents/chips in either the exciter ring or the Vehicle Speed Sensor (VSS) and air gaps between the VSS and the exciter ring..."
