Hi there I have a 2004 Jaguar XJ8 with an intermittent DSC light on the cluster. It doesn't come on every day but it is on most of the time. When the light is off you can turn it on by pushing the DSC button on the J gate. But once the light comes on (of its own accord) you cannot turn the light off by pushing the button.

The car has about 70k miles.

I used my scan tool to go into the ABS module and it gave me these codes:

U2527 CAN network 2 communication bus off ‑ transmit error

U1901 CAN network 2 communication bus fault ‑ receive error

With the car driving I also used the scan tool to read all four wheel speed sensors. They are all operating fine as far as I can tell and are within 1mph of each other with no weird spikes or anything like that.

The car also has a new battery.

Everything I've read so far about DSC issues people recommend cleaning the wheel speed sensors along with the tone ring on the axle. I guess I'm wondering if those codes mean anything to anyone and whether or not it's worth it to try and clean the sensors if they all apparently read correctly with the scan tool.

Thanks for you time.
