1996 Ram 1500 regular cab with the RWAL. Both the ABS light and the brake light are on and I could use some guidance determining exactly what the cause is.


I have watched numerous videos and read as much as I can on this topic on forums and such, but I can't seem to find out exactly what's going on.

Perhaps a clue is that I had reset the codes by disconnecting the battery for a time, and the lights came back on just from turning the key to the on position ( not even starting the vehicle or pressing the brake ).


I've watched videos on how to trigger the system to start blinking to display the code, but I can not locate the ( wire ? connector ? ) to ground out the pin / wire to trigger this behaviour. The videos are not exactly clear where that connector is. I'm not even sure my truck has it.


I'd like to know if there is a way to test the electrical ABS valve body. I've found the ABS ("CAB" ) controller in the dash, but I don't know how to test that either.


But perhaps I'm barking up the wrong tree anyway ? I'm trying to pinpoint the problem without just throwing parts at it.

Thanks for any guidance here.

 

Watching.

I have a similar issue with my truck with the brake light coming on periodically, but the brakes work fine. I need to obtain the brake/ABS code to help determine what may be going on...

 

The brake warning comes on with the ABS warning but there are other faults that can trigger the brake warning alone, e.g. unequal brake pressure between the two circuits. The RWAL "service diag signal" is on pin 13 in the DLC/OBD2 connector, should be a black wire. For older pre-OBD2 trucks there is a connector under the dash.
