Suspension fault

I recently got a suspension fault message on my Xjr -99 with adaptive cats suspension. The Obd code reader that I have shows nine fault codes with the Body processer module and one of them is Scp vehicle speed signal - invalid or missing signal. I have checked the speed signal cables that are behind each wheel and they looked ok..

The CATS system is basically stand alone. The input from the speed sensor is only to activate the CATS when the speed is more than some 5 mph. Thereafter, the CATS module receives signals only from the accelerometers. It stiffens the suspension on harder cornering (to reduce roll) and also on harder breaking to reduce the "nose dive".

If your receipt shows the brand and model of the shocks you can probably look up whether they are CATS enabled. The only ones I know of that work with CATS are made by Bilstein.
