Have a 2012 Pro 4X - 295,000 miles on it - well taken care of and serviced regularly - a couple days ago I went to back a small jon boat into mom's pond - so I put it in 4L and put DIFF LOCK on just in case I went back too far. All went fine - never even got into mud.

Pulled boat out - turned DIFF LOCK off and put in 2 wheel drive - backed up a bit and then went to pull around the house - DIFF LOCK and SLIP LIGHT stayed on. I have tried several times to get them off by driving it - swapped relays - checked every fuse - disconected neg side of battery over night - and still they both come on - then when you start to drive they go off and the ABS - SLIP LIGHT - VDC LIGHTS come on - and stay on

Vehicle is at the dealers - they are clueless and tell me I need a new rear-end.

Doesn't make a lick of sense - these are highway miles - vehicle is not been dogged or thrashed - 4WD is used when it snows and almost always in 4H.

Any ideas or suggestions?

I've had my diff lock light come on and then the others, for no apparent reason. I go through an engage/disengage routine and it usually takes care of it for a few thousand miles.

Did you check the wires and connector at the diff? Water could've shorted your wires or bad connector.

I have 72k on my 08 & won't even think about messing with the Elock anymore. I'm sure as soon as I turn it on the thing will grenade. Do you live in that truck ?

Probably got water inside the rear wheel disk brake/emergency brake drum. Contaminates on the sensor could cause it to read incorrectly. I'd try taking the wheel apart and cleaning the ABS sensor. You just remove the wheel, brake caliper and then the rotor to access this area. Quick and simple job. Also check the cog on the axle that the ABS sensor reads any metal debri from the brakes jammed in there will also cause incorrect readings which will set all those lights.

If that doesn't solve it then water probably entered inside one of the sensors and damaged it. I'm fairly certain they are sold in pairs so you would be replacing both the rear ones at the same time. You can also bring it to a dealership for diagnostic with their specialized Nissan computer equipment (consult III), but they will charge you.

I have a 2102 titan with 47,000 miles on it and those lights came on today. Dealer said diff lock sensor but not sure. Reading a lot that could be ABS sensor.

This is for new readers with this problem. I had the same indicator light issue come on with my 2013 Titan Pro4X at 96,000km. What I observed was some sweating at the drivers axle seal as well as the pinion seal. I did some research and found that because of where the differential vents are located, they can plug up, which in turn pressurizes the diff case and forces oil to sweat out around the seals. When the oil gets low enough in the diff, it no longer contacts the diff lock sensor and sets off the warning light which in turn disables the traction control and eventually sets an ABS code. When I removed the differential breather, there was some pressure inside the diff, which validated my theory. I cleaned the breather as it was a weekend (replaced it as soon as I could), and changed the diff fluid. Within 3 days, all the warning lights went off, the seals stopped sweating and it has been good for over a month. I have added that to my maintenance book to replace the breather every 50,000 km and I am also looking at relocating it up on to the frame with a hose to the diff.
