Hi i have a 2003 2.8d redriver addition jeep i was going down the motorway when my abs light came on +my speedo stoped working + break worning light came on and engine management light. The jeep runs fine only 48000 mile with full history whats the problem can any one help.

I believe you have a speedo which works off an electronic sender unit mounted to the side of the transmission just as the old mechanical style does. Check the disconnect plug at the sender unit for loose or dirty connection, then remove the sender and inspect for worn or broken parts.

your main computer,(ecm) is bad,need to replace it

brake light and abs light for the car is a transmission problem.

for the speedo its going to be a speed sensor and with the ABS light on it will probably be an ABS sensor you'll have to figure out which one.Does the speedo go crazy sometimes or just doesn't work at all

motorway so must be english and a uk reg vehicle ,well this is not my favourite make of vehicle the dreaded renault ,So the lights are on and you have a juddering .Well firstly the lights ,the service light and the ABs light are not connected ,the service light can be put out by holding the button down depending in the layout ,anything later than 2005 is a dealer only software job ,the ABS could jsut be damp in the wheel sensors and with the rain in the UK then i wouldnt worry about this too much ,driving a car with no ABS isnt a problem as the brakes still work manually just like a good old ford cortina ,dont drive fast in the rain and slow down with the gears old school style.The juddering is worring me though so i would advise that you go back to the garage that fitted the brakes and ask them nicely to have a look in case one of the caliper retaining bolts is loose although i feel you may need new brake disks ,now take a tip from a old man here wear the high heels and LBD.act dumb and pretend you know nothing and i bet you get this car sorted and the service light put out for free but its not difficult so any problems on this part and i will scan the alldata book on how to do it for you.Excepts its pouring down here in sunny spain and the book is in the garage but iam sure the garage will do it for you its just a case of holding down button A and turning the ignition then it counts down and the service light is reset.See how you get on any queiries just answer this post

it reads from the abs. and the abs read from the wheels but speedo only reads from the pass side wheel sensor.

Check for codes

You have an ABS Light on,that should
tell you something,like check for codes
& diagnose that system

if all this happend close togeter it could be that the ECU is cooked I say this because the speedo, trans and ABS aree all controled by it

Possible problem with one or more wheel speed sensors, or the vehicle speed sensor, or the related wiring connections. I have found rotted out wiring harnesses or connections on wheel speed sensors numerous times. Hope this helps.

sounds like a ABS sensor is out, one sensor can throw off your computer. Get the code red at Autozone for free.
