Yesterday my S type jag 2003showed a ABS/DSC/Gearbox alternating fault on my dashboard. Every time I switch on the ignition and start to move forward in drive at between 2 and 5 miles an hour, the car seems like the breaks have been applied then lurches forward and then runs ok for the rest of the journey utill the ignitin is switched off again. Help.

Check all wiring under the car. Transmission and ABS are not talking to the bcm. Maybe rat damage or something you ran over.

Get your vehicle checked by a Good mechanic as soon as possible!!!
EBD Translates as 'Electronic Brakeforce Distribution'. This means there is a problem with your brakes or the electronics controlling them. EBD is part of your Antilock Braking System.
It could be as simple as a faulty sensor or something more serious such as a failed brake caliper.

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Antilock brake system.TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module

In order to help you I would need the contro system read for fault codes and go from there.

check the brake fluid level

The DSC light stands for Dynamic Skid Control or in lawmen's terms Traction Control. If the light stays on you have a problem with this system. You will need to have it diagnosed by someone who has the tools and expertise to find the problem. More than likely you are going to have to take it to a Jaguar dealer.

hi,change the gear box solonied c.should b ok than ali g autos birmingham 07971335303

DSC is your dynamic stability control, you probably went over something really hard and caused a fault, this is a normal response. If the fault stays on disconnect the battery and leave for five mins then reconnect, if you still have the same robelem your DSC module is faulty, it is located on the rear axel it is a block with an arm connected to the axel mid way on the axel.
Has nothing to do with yor abs the juddering was probably you driving over something which triggered the fault.
hope this helps

speedometer get speed signal from ABS. ABS and DSC are two functionality in same ECU. 
You shall read faults from ABS/DSC ECU.
Most frequently, there are problems with speed sensors on wheels.
With ignition on, you shall measure voltage on both wires (- pole of voltmeter shall be connected on vehicle ground). You will see one sensor without voltage supply. This will sensor with problem. you can, for check, change sensors on same axle (left and right). 
Switch ignition off, and on. 
If voltage supply missing will go on another side (with faulty sensor), you will be sure that is problem is sensor.

Hi,
Check carefully ant wiring loom you may have moved to replace the shaft.

As you were only working on mechanical items, and just moving electrical systems, it is almost certainly a break in the loom or a faulty connector in that area. You may need to unwrap the loom a bit.

Hope this solves it for you.
Thanks for using Fixya!
