HI Zugy, Did you get this fixed and what was it? I've exactly the same thing on my 93 FWB1993 Fleetwood Brougham
I've a problem like this. The Digital speed/fuel display is completely out! I get all the side signals when the key is first turned on but no speed.
I have checked all the fuses and the single 5 amp one under the steering. I have checked all the lights and dimmers but to na avail.
The readings I get from the diagnostics point to 144 on the CCM, and 30,33,35,37 on the ABS/TC system. Could it be the main brain??:suspect:
Thanks for any pointers.
