How to determine whether is is the speed sensors or the ABS unit

 

Ken, get the codes read. If you are getting a C11X5 code (where X is 4, 5, 6, or 7, which will tell you which wheel is acting up), then this will confirm a bad wheel speed sensor.. No codes or other codes would be pointing towards a bad ABS unit.

 

Btw, you'll need a unit that reads "c" codes for a Jag. A less expensive "elm" type will not do it.

Look for an OBDII scanner that has the 1.5 version and PIC18F25K80

Viecar Bluetooth is fairly cheap, like $19 on amazon. It will read C codes. I originally got the Bluetooth because i was using my mobile to run Torque, and when i connect to the OBDII using wifi then i would loose connectivity to internet , With Bluetooth, i was connected to internet via mobile data and to OBDII via bluetooth,

Later on i got the Android 10" Mirror for my x type and now i can use either one, but bluetooth tested faster for me, i can see my information in (almost) real time,

 

Thanks. I suspect it is a wheel speed sensor

 

Thanks. Good point

 

I tested the symptoms yesterday,

Start the car, drive under 40 MPH, the light did not come on.

Once you go over 40 MPH, the light triggers.

I have error codes on my OBDII for all 4 sensors, although only one is bad, i know for a fact, the front left.


This is the OBDII scanner i am using
