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.
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
2) Remove the centre console, drill the rivets and attack from
above. Same tools needed, just you can see what you're doing.
favoured Option 1. YMMV!
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.
