I have a 2001 XK8 and last night the ASC/TRAC not available

Customer Question

I have a 2001 XK8 and last night the ASC/TRAC not available messages came on and it indicated it was in failsafe mode. I was essentially just driving at idle speed, could not get it about 20 mph. I heard that humidity might be the cause and after it sat for a few hours in a parking garage the problem resolved.
JA: How many miles are on the car? What size is the engine?
Customer: 95000, V8 4 liter
JA: Are you fixing your XK8 yourself? What have you tried so far?
Customer: that is way above my pay grade, so far I have done nothing
JA: Anything else you want the mechanic to know before I connect you?
Customer: i think that is it for now

Hi, I'm Chad ,Welcome To JustAnswer, I'm reviewing your question and I will be be posting a replay ASAP

Expert:  Chad Farhat replied 7 months ago.

the most possible causes is the ABS pump itself based on my experience on those xk8 ,especial if you let it set and come back and everything went back to normal.

but testing is needed since the system consist of several sensors other then then the pump, you need a diagnostic scan with a jaguar scanner or equivalent to retrieve the fault codes from the abs system, just a simple code reader want do since it can not communicate with that abs module .

Please let me know

Thank You
