Check and see if it is still locked in. Check sensor to make sure it is not sending false signal up to the light.

How do I fix the diff light in my Jeep switch board ?


Check wiring under/behind the switch chances are it is a "dead short" which is keeping your light on. Look for bare wire(s). Peace. God bless

Tod system on 98 bighorn check light and rear wheels flashing on dash when ingnition on and stays on not pulling front diff out of ingagement vsv are ok and work no power at them but have earth on both so...


check out detent limit switches on gear box and transfer case for continuity and open circuit when pressed(on /off switch) these are feed back signals to indicate it has locked into 4x4 or 2x4, if one of these dont work properly system locks up and wont do anything any more. also check front one on diff near actuator, common problem. check actuator is working properly when vacuum applied and removed. can remove this and bench test unit,some oil will be lost when removed for bench test and you can check colar inside diff slides back and forth to lock axle.

I have Landrover Discovery TD5 and the ABS and TC light are on. Periodically the Diff lock light shows. It has been plugged into diagnostics at local garage, but NO FAULT WITH ABS PICK UPS!! Advice...


Sounds like a faulty Diff Lock switch to me.
Most of the D2 models till late 03 model year use a version of firmware on the SLABS ECU that when diff-lock is detected puts the ABS and Traction Control systems into a lower response mode. Late model vehicles came with factory fit diff-lock linkages as a option, and the firmware was revised to allow this to operate in conjunction with the traction control.
Therefore ABS and TC illuminating (but with no HDC) means your TC/ABS is in the lower performing mode, and your diff-lock may be in, but more likely the £12 switch has broken, and needs replacing. It's a bugger of a job, and can be done from underneath the vehicle (did mine this way) the switch is p/no PRC2911, and just unscrews. It's located just behind the diff-lock stud above where the front prop fits.
Your options are thus:
1) Remove the front prop. Work blind and try and change it by feel alone. Helps if you can clean the area off before too, don't want any rubbish falling in the box! Unplug & Undo the switch, IIRC it's a 12mm head, and a stubby spanner is the tool for the job. Remove, swap the lower nut from the old switch to the new one (important for the length) and put back in. Don't do up too tight, or it may shear off (as my friend did 2 days after I did mine! He kept tightening it...) Pop the connections on and the front prop and the fault should go away. You could also just disconnect the switch if you want. IIRC open circuit is no-diff lock anyway, but if that's not correct then make up a link with some spade connectors and link it out then.
2) Remove the centre console, drill the rivets and attack from above. Same tools needed, just you can see what you're doing.
I favoured Option 1. YMMV!

I have 2003 land rover discovery and the abs light just cam on. also a ct light came on... whats the problem? plz help


Ok, you either have an expensive problem, or a very cheap one. And it all depends upon the number of lights on the dash.
If you have ABS and TC showing, then you may just have a diff-lock switch fault (and an intermittent H shaped amber light also which is the diff-lock indicator). This is a software issue with the SLABS ECU and is showing that due to diff-lock the ABS and TC are in a lower response setting. Later trucks don't have this problem (03 model year onwards) as the software was updated. The diff lock switch is about £12, and it's a bugger of a job. It can be done from underneath the vehicle (did mine this way) or from the cabin, and the switch is p/no PRC2911, and just unscrews. It's located just behind the diff-lock stud above where the front prop fits.
Your options are thus:
1) Remove the front prop. Work blind and try and change it by feel alone. Helps if you can clean the area off before too, don't want any rubbish falling in the box!

If however you have ABS, TC and Hill Descent (little picture of a truck going downhill) then you sadly have an ABS issue which suggests either Wheel Bearing, ABS Sensor Fault, or Shuttle valve. Best to get it to a dealer and on the computer for them to diagnose what exactly is wrong.

Your whirring noise and loss of power may indicate the diff-lock is engaging occasionally and may indicate damage to the transfer box.

Diff lock and abs lights


Check to see if the plugs on the wheels are plugged in check that the pins are all the way into socket, that your ABS problem, next check to see if you knocked loose the wire on the differential most likely cause and be sure to top off power steering fluid. Check that the fluid level is ok on the Diff. if you need more help let me know and thanks for using Fix-ya and rate if this was helpful.

Timing belt replacement 1997 lexus lx 450: when?


well don , if this is a 4wd , actually even if it wasn't i show it to have locking diff(s) , if you have 4wd i show you to have a switch and a light somewhere on dash display indicating if it is locked in or not . , if you look at the passenger side of the rear differential you might see some electronical gizmo attached to it . i recently worked on a lx470 , it was awesome , i cracked the woodgrain cover around the power window switch , ouch , it cost $500 just for that little piece of woodgrain , lexus is very proud of their parts , lol , enjoy that vehicle . i would sure appreciate a FIX YA vote . thank you .
