What do ABS, Svc 4WD, Svc Park Assist, and Anti-Skid lights have in common?

[OggyOggy]

After installing a Banks Monster Exhaust all four of these lights/warnings have appeared. It must be electrical, I didn't have any of these lights until after the exhaust install. I disconnected batteries for 1/2 hour to clear and reconnected, all lights/warnings reappeared. Did I bump a connector? wire?

Any ideas?

Any chance you might have a bumped a wire near or around the rear axle area?

I see no truck information. Not sure what the truck in question is.

You know, I've been trying to get my truck info to show up and I can't get it to do so...

2012 Ram 2500 Longhorn 6.7 CTD, Banks Ram-Air, Banks Monster Exhaust, Edge Evolution Tuner, Severe Duty Brakes, Load Lifter 5000 bags,

I'm sure I bumped all kinds of wires. A thread on a different forum suggested the ABS sensor wire on the right side of the differential, their's was burned. I checked mind and it looks fine not pulled, burned, or damaged in any way.

I know I'm talking to myself here but maybe someone else will find this helpful. After a bit of research suggesting I found that all of these problems may a single cause in a faulty ABS sensor. Right below where I worked on the exhaust is the wire from the passenger rear ABS sensor. I found a video on YouTube of a person with a 2012 Ram 1500 with exactly the same problem. They replaced the sensor and fixed all 4 issues. I've ordered one and will report back if that fixes it.

I would look closely more at the wiring in that area....before I purchased a sensor.
IIRC.....that sensor is way out at the wheel end, and almost impossible to damage in the grand scheme of things.

Look at the wiring a little more closely where the exhaust goes over the axle.

I had already ordered the part ($22) from Autozone and had picked it up a few minutes before I read your post. Since I already had the part I simply replaced it. While under there I remembered that I'd dropped the spare tire to give me room to work so I checked wiring around that as well, didn't find anything. Then I gave a the old sensor and cable a thorough examination. The sensor itself was filthy and the cable had a few bends in it I didn't like. Praying like crazy I put the key in and turned it to on, all the lights came on as usual, and then all went away, started the truck and poof... no more ABS, 4x4, parking sensor, or traction control warnings.

I hope this can be of use to someone in the future. Paying a dealer to troubleshoot it something I try to avoid at all costs. I'm going to change the title of this thread if I can so it's more evident a solution was found.

Good to know it was a relatively cheap fix. Thanks for the update.
