Dash Lights Blinking

Maybe this will help some people in the future.

Dash lights blinking:
1. NO CHECK ENGINE light on - important because you will have a different problem
2. 4wd Hi and Lo blinking
3. ABS constant on
4. VSC constant on
(don't pay attention to the seatbelt or headlights)


Did some research and found that it could be a faulty wheel sensor or the wiring leading to the senors. Started in the front and removed the plug going into the sensors and checked the wiring. No visible damage no dirt. Moved to the back of the truck and removed the plugs and traced it back to the plug in between the gas tank and rear diff. You can see the weak point of the wires and one had broke free. There was not enough wire on the plug side to repair so I ordered an OEM rear speed sensor wiring harness hoping that would correct my problem.


It was not a hard job. Just had to removed the plugs from the sensors and trace it back to the bracket. Everything was included in the new harness including an updated bracket that raises the plug up a little.



I did remove the battery cable while doing this. When I had it everything hooked up, the VSC and ABS lights were still on. I drove it 20 feet and all lights went off. 4wd works and no more lights on the dash.

Again, I want everyone to know that my CEL was NOT on, thus O'Riley Auto said that they couldn't read ABS codes with their scanner.

After a few quick stops at a couple of HVAC parts warehouses I went to work on a few service calls. Someone, somewhere, somehow did this to my passenger side. Just my luck. At least my dash lights are off.

 

Tag, thanks for the info
