About a year ago, the ABS and TRAC error messages started to
appear intermittently in the speedometer message area of my
�01 XK8 along with the simultaneous illumination of the ABS
warning light. As is often the course for this problem, the
messages and light eventually stayed on continuously when
the car was being driven. A review of the archives confirmed
that this is a common problem, with a number of posters
providing useful insight. y2Kxk8 recently noted (based on an
earlier post from another Jag-lover) that the simultaneous
appearance of the messages and ABS light did not indicate a
bad wheel sensor, etc., but instead failure of the solder
joints on the circuit board that provide power the ABS
motor. He described a simple fix of opening the module and
re-soldering the failed joints. Motorman also had a number
of useful posts on this topic and indicated that the repair
is straight forward. Other posters also provided added
insight. However, I couldn�t find photos showing how the
module was removed, opened and repaired.
I recently completed the successful repair of my module.
Excluding the time spent taking photos, waiting for the RTV
on the module cover to cure (24 hr), and subsequently
bleeding the brakes, I completed the job in a couple of
hours. As others have noted, it is a simple repair that can
easily be completed by the normal DIY mechanic.
Initially I attempted to use a method recommended by Jeff
Kline for removing the module from the car, i.e., remove the
four module-support-to-frame bolts and then push the lower
portion of the ABS assembly toward the engine to provide
clearance for removal of the module. This method avoids
removing the hydraulic hoses and the need to later bleed the
brakes. However, despite some bending of the hydraulic lines
and lots of pushing, I could not pull the module free. I
chose to replace the module-frame bolts, remove the four
hydraulic lines (the normally recommended means of access to
the module), and slide the module forward.
