Abs light. Faking it

Go on eBay buy one of those time circuit boards.
Wire it to your ignition switch and to the abs light.
Set the time switch to about 3 seconds or so.
When you turn the key on the the abs light will light for about 3 seconds or so and then go out.

 

Where are you reading this code?
You might have a couple problems.
Check your rear speed sensor. If you can reach it, push it in to make sure it is up against the tone ring.

Check the power at your center pin. Test light. Doesn't give you volts but you'll know if you have power.

 

Lol. That reminds me of someone that will work themselves to death so they won't have to actually work.

By the time you rig up that contraption you'll have the problem fixed.

It's more than likely very simple.

A corroded plug on the axle.
A burnt out light.
A bad wheel sensor.
A faulty signal in the pig tail.
A broken wire between the axle connector and the light.

Just fix it.
Spend $150 at a Loves Tire Shop if you can't do the work.
I've had them find ABS probs for me before and fix them pretty quickly.

 

I had a similar problem. My ABS warning light was steady on in the dash of truck. I couldn't find the problem. Previous owner or mechanic tried to troubleshoot the repair by piercing the wires from the ABS module under the cab. By doing this there was 15 wires that had to be fixed or replaced. They all corroded inside the wire insulation. Couldn't see problem from looking at them.
Probably the best $1,000 I spent on the truck. I'm not the fastest at hunting electrical gremlins. At the time, this was the first truck I owned, that I needed ABS to the trailer.

 

Did they open up the pigtail connection junction box and check inside for power at the center pin?

 

Still better to get it fixed correctly than a hide it measure that you hope fools a new employers inspection.
Not a good way to start a relationship.
Hope you figure it out relatively inexpensively.
Keep us informed.
Someone else will have the same symptoms eventually.

 

You need a competent Mechanic. The systems aren’t complicated. Pay more per hour, at the Dealer if need be. Save more in the long run. Average Truckstop can’t figure it out with their diagnostic box, time to go to the Truck Manufacterers Dealership.
