Fill the master cylinder with brake fluid. Don't check it, fill it.
ABS, slip and VDC lights on
Researched the forum and found similar threads, but thought I would check to see if anyone has had this issue recently.
When I start the truck, I just get the slip and diff lock lights.

Then after driving for a few seconds at low speeds, the lights switch to ABS, slip and VDC. (Diff lock light comes off)

I have scanned for codes with an OBDII code reader and no codes were found.
After the truck cools over night, the lights are gone. The next day, the same problem comes back. (start the truck, get the VDC and diff light..... drive and get the ABS, slip and VDC)
I'm hoping this is just a loose/dirty ABS sensor which I will try to check on all 4 wheels. Anything else to check for intermittent issues?
Thx.

You bet, topped off the brake fluid. No change.
I rotated all tires, (it was due) so gave me a good chance to look at all the ABS sensors.
No damage by wires or connections that I could see, and I used a multi-meter to test all of them. They all read about the same OHM measurement of around .450 MOhms
I tried the AC voltage measurement too by spinning the wheel, but on all 4 wheels I pretty much saw 0 volts. So either I wasn't spinning fast enough, or I just couldn't get my meter to connect correctly.
I've also tried the "read codes" method by pushing the gas pedal 5 times, waiting and holding it down for 10 and so on.
I believe it's still not throwing codes. (according to this site)

Now, my battery is suspect.
It's the original battery, so probably close to 8 years old and there is some heavy blue powder on the positive terminal.
I'm going to give it a full cleaning and tender the battery back up to charge.
I will do some more tests and report back.
I might try to visually inspect the diff electronic connections (again) to see if there is any damage or dirtyness, but I highly doubt it.
I've also thought about buying the datascanII software. Perhaps it will read ABS codes?
I might just give up and take it to my Indy shop.
Update 2.0:
Truck still throws the same light errors. Damn! I honestly thought I had it.
I cleaned up the massive heavily corroded postive terminal, and decided to put in a new battery this morning. (I was due for one anyway)
Thought I was golden.
Took a 30 minute drive out to the lake, and bam, the diff lock and slip lights are back.
Eventually, the ABS, slip and VDC lights came on and the diff lock light off. Same as usual.
What's interesting, is that I started to think this might be heat related. The lights seem to be off more if the truck sits for a bit. Especially overnight.
I was at the lake, trying to check the positive side of the battery connections again and sat in the truck for about 2 minutes with the engine running. The diff light and slip were randomly shutting off and on with no pattern. I eventually came home and the lights were on full of course.
It makes me wonder that temperature somewhere might be contributing to my problem.
Once I got home, I decided to try something different. I went under to the rear diff and unplugged the two connectors. I'm not sure what they are for.
I assume one is to activate the diff lock, and the other may be a sensor, but I really have no clue.
I left both plugs unplugged and took the truck out for a drive.
No lights what so ever.
I even went to an open parking lot and did some speed tests. It was lightly raining out, so I could hammer the gas from a stopped position and spin the rear tires on the wet pavement.
The VDC kicked in as normal.
Tried again with VDC off, and the tires spun even more as it normally should. (the "cutting" of engine throttle was dis-engaged and thus working normally)
I was thinking in my mind, "I need to heat up the rear diff", but after about 20 minutes of driving around in the parking lot and through the streets on the way home, the dash lights never came on.
I will maybe pull the plug on the rear diff to see what the oil is like, but I just changed it 2 years ago.
Could there be a bad sensor in the rear diff?
FWIW, my axle seals are clean, and my diff breather should be working normally. I clean it a lot and make sure I can swivel it and move it slightly up and down.
Below is a picture of the two connectors I unplugged. You can easily tell which wire plugs into the correct connector.
It was also interesting to note that with both these connectors unplugged, there were no dash errors at all.
I did not try to put the truck in the 4Lo and activate the diff lock, but I assume it would have not worked.
For fun, I may try that tomorrow and see what happens.
Thanks for any other feed back you guys can provide. Most appreciated.
Oh, and the Frontier is one my favorite trucks of all time!
