I have a 355 and when the car reaches 35 MPH the ABS light comes on. When the car is turned off the ABS light goes off untill the car reaches speed again. The dealer here only has a SD-2 which won't link up to my computer. When I read the code by putting the fuse in the socket, I come up with the code 5.4 Low pressure. When I bought the car it came with that fault. Any body has any ideas?
Without the real code from the computer it will be hard to say. Just do a check and see if all of the rings and sensors for the abs are okay. And also tell your dealer to call FNA for the updated software for the SD2. It is now capable of diagnosing almost all of the past models. (348,355,456GT,550,etc.)
The dealer has the backwards capable software for the SD2 and as what he was told by FNA it only works 70% of the time. Mine is one that falls in the 30% not capatable range. What are the rings?
