grandfather recently bought 95 ram 2500 4x4 with 2wheel abs at auction with the abs/brake light on, would like to take care of it since I'm assuming it has to do with the brakes fading the more you push them. 

 

So i grounded the wire wire under the dash to make the lights flash, looked at the chest chart I found online and hope someone can tell me how to fix 3, I'm assuming you only count the short flashes.

Basically take the module out have it rebuilt or the dump valve wiring is disconnected or open circuit. I would test this first before having the module replaced or rebuilt.

I will test definitely before sending out the the module. 

Just in case, make sure the wires going to the ABS sensor in the differential are hooked up and working. The ABS and brake lights being on also indicate a fault with the ABS sensor.

 Hope I'm not too far out of line.

If I remember correctly the day after We sent out the module for rebuild since it was bad, I was installing a new gooseneck in the truck and found a bad section of wiring, did end up repairing it and when the module came bad the lights went off within 5 mins of driving so it may of been one or both I'll never know, but I know what I did to resolve it! 

Glad you got it fixed.
