2001 S Type Jaguar ABS and Traction Control fault lights on

THE 1ST THING TO CHECK I BOTH SPEED CONTROL SENSORS LOCATED ON THE BACK SIDE OF YOUR WHEEL HUB...SOMETIMES THEY CAN BE CLEANED..TRUN WHEEL HARD RIGHT FOR RIGHT CABLE HARD LEFT FOR LEFT CABLE...PULL PIN OUT THEN CABLE VERY EASY TO REPLACE

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

ABS = Anti-lock Brake System.
TC = Traction Control System (Engine Control Module).
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS & TC Electronic Control Units (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.
I suspect bad brake pedal switch, but you should scan the ABS & TC ECU's.

BETTER BE SAFE AND TOW ..

hope you can see this

your traction control mechanism uses the abs breaks to slow the spinning and give you better traction. i'm thinking your traction control sensor has gone bad

the little teeth on the front axles maybe hanging up give these websites a try www.autozone.com and www.alldatadiy.com if all fails stop by your local Jaguar dealership in the parts department and they can print you out pictures and diagrams wish you the best Michigan Man.

Your best to get the system "code read". Withhout seeing the carits impossible to say, it could be anything. Sensor failure, wiring fault etc. Make friends with a good Mechanic.

IF YOU ALREADY HAVE THE ABS FIXED THE LIGTH AUTOMATYCALY TURNS OFF BUT IF THE ABS IS STILL UNABLE THE ABS LIGTH AND THE TRAC OFF LIGTH WILL REMAIN ON

Could be your Rear ABS sensors , as that is the sensor that works for ABS and Traction control.
