Hello All,
I am asking assistance with my Jag ABS, Traction and Engin light stay on. I connected my P1000 and received a code that called out a bad right wheel speed sensor. I replaced both left and right sensors. However, the ABS, Traction and engin light stayed on. I re-connect the P1000 and received no error codes. But the ABS, Traction and engin light still would not go out. I used the P1000 to clear the errors and that also did not correct the problem. I removed the neg. Battery terminal, that did not work. Touched both neg and pos terminals together. That did not work.
I performed a voltage check at the right and left wheel sensor's connector and got 0 voltage reading. The ignition switch was on during the voltage checks. If someone have a schematic that I can troubleshoot,. would be a big help. I need to know why there is 0 volts at the wheel sensor's left and right connector? Thanks

 

quarries, having 0 volts at those connectors is normal. The sensors develop their own voltage through transformer action (aka, hall effect). The faster you drive, the larger the voltage gets and the higher the frequency gets (hence how the car knows how fast you are driving). You mention that you had a bad right wheel speed sensor, was that the front or rear wheel? The front, there is part of the sensor in the wheel bearing. So, if you had the wheel bearing replaced, did they replace the wheel bearing in the correct orientation (if not, the pickup teeth are in the wrong spot, sensor will not work). If it was the rear wheel, you needed to look down in the hole where the sensor sits and see if you can see the reluctance ring that sits in there (will look like a metal band about 1/2" wide with square holes cut in it held tight against a metal shaft). This metal band is known to rust and break loose, causing the wheel to loose signal.

You don't mention taking the car for a drive. Have you driven it since the replacement? If no, start there. The other thing that I would say is to take it for a drive and if you have the "DSC button" on the center console, depress the button and see if the lights go out. Press it again just to make sure. You can then check your codes. If you have the ABS and DSC lights on, you should have a code that you can read to help guide you in the right direction. I would also be checking the fuses for the ABS module (F3 in the engine bay fuse box) and fuse F96 in the passenger fuse box. It may be possible that during your work, somehow the fuses got damaged.

Lets see what you have at this point and then we can go from there.

 

Not sure what kind of scanner you're using, but some of them won't read proprietary Jaguar codes, especially those associated with the ABS system. I had a weird problem with my 2005 X-Type sedan and it turned out to the ABS module which I sent out to be repaired. You'll probably hear from Thermo, the X-Type guru who diagnosed my problem.

Good luck. .
