THe passenger seat is stuck in one position and with the memory module installed or not installed, the motors sound like they are trying to move the seat when the buttons are pushed but it never moves. Ideas?
THanks

Swap modules side-to-side and try again.

Can you do this even though the drivers side has 3 plugs and the passenger has only two?
Does a replacement used seat module require programming?
Thanks

Info we got when I worked at the dealer and had problems with seat module configuration. I called TECH LINE and was instructed on how to handle the problem.

Months later Jaguar issued a TECH TIP for this issue.

ALL X100 modules are 'swappable'.

Models – XK8/XKR 2001/2002 MY
Symptom: PECUS D or PECUS P warning after replacing seat modules
Information: After replacing one or both seat modules, a technician will see a PECUS message on the dash. When looking on the WDS, there will be no programming option for the seat modules. To repair a tech must locate a 2003-04 XK, install the seat module in that vehicle, and then program with WDS. The only side that can be programmed is the driver's side; therefore a passenger seat module must be placed in the driver's position and programmed. After programming install modules in original car, PECUS message should be gone.
