Traction control, service abs and main brake light on

[DBaker7777]

I have a 2016 Ram 1500 and my son washed my truck with a pressure washer and not sure if that has anything to do with it as he cleaned the wheel areas with it but next day I was driving it the service abs, traction control and main brake light all came on. Any ideas what I may need to look for? It is also lifted. Thank you

Could be the ABS speed sensor or brake pads not sliding freely on caliper frame or calipers could be not moving freely or brake fluid could be low

I have the same issue. Any resolution?

Based on your description of the problem and how it started, I think "Cammed" has it right and the speed sensor is a good place to start. If you know of a guy who has a good OBDII scanner they should be able to see which wheel sensor is bad (if that's the problem). Or if you swing by Autozone/OReilly's parts stores, they should be able to read the fault for free. You might also check the wiring connectors too, just in case (plus that doesn't cost any $$).

Another common issue that causes the fault you're seeing is a faulty brake switch ...above the brake pedal. It's easy to replace w/o significant mechanical skills. But read the codes first so you're not replacing a part which is 'good'.

Let us know what fixes it.
