Got abs/brake warning light after heap sits for 2 weeks. Reset light by disconnecting battery. Heap sits another 2 weeks & got light again. Pulled RWAL fuse. Wouldn't reset. Tried jumping OBD 2 terminal 3 to gnd. 4 flashes without long flash. I get 4 flashes, pause, 4 flashes etc. Is this good code? Had to disconnect battery to reset. Did I gnd right terminal? How to diagnose next time this happens? Please!!!

 

2 or 4 wheel ABS?

For 2 wheel, it's generally the rear wheel speed sensor in the diff.

Welcome to DF!

 

It's 2 wheel drive, 2 wheel ABS, 360cube, 4 speed auto. Service brake works fine. Never tried red neck ABS test! Thanks for the help.

 

I swear dodge sent out a covert signal to cause trucks to do this...mine did it yesterday while working on my outlet wiring...

 

i feel for yah both. putting leds in the map lights and broke sunglass tab off buddy did it the week before.
post back after fix. my light wanted to stay on longer then usual tonight when i left work( about 30 seconds)after startup.

 

If it sat for a while, just try removing and cleaning the plug/connection to the sensor on the rear diff housing. After cleaning, put it on and off a few times. May just be a corroded connection.

 

thanks will look at it this weekend.
