ABS light on. Where to start.

[Driftless]

The ABS light in our 2005 CRD came on the other day. I have not yet checked to see if the ABS is actually working or not, and I know that is my first step. I have done some online research and I have been pointed in several directions - sensors and pump seem to be the most popular. The speedo is working so I don't believe it is the rear ABS/Speedometer sensor... but I won't rule anything out.

My question is: where do I start? (After checking to see if it actually working or not) Oh, I did just do a brake job a couple of weeks ago pads and rotors on all four corners, but the ABS light just came on so I don't think the two are related.

I did plug in a code reader but it came up clear, so that was no help.

Thanks in advance.

I'd test it out first. Then try a fuse. Actually, it should be easy to find out if the pump works, should do the grinding thing.

Check the sensors on the wheels for dirt or frayed cables.

Most code pullers will not read ABS codes,get the code pulled as that is the 1st step in finding the problem.

I did try to see if the ABS is working... amazing that you can't find a patch of gravel when you want one! No ABS.

I did check the fuse, but only visual. I didn't take time to grab my multimeter. So that will be step one.

I also need to adjust the handbrake so I will have the Jeep up on jack stands, I will check the sensors. Step B.

I guess when I take it in for the recall I can have them pull the ABS code!

Of course this happens just before an overland trip to Montana. At least it happened here in the driveway and not on some mountain fire road descending with a Libby full of gear!

My 2005 has no wheel sensors at all... stock.:icon_confused:

That would be due to ABS being a option till '06 when it became standard on KJ's.
