I would think it will probably be quite difficult to do, as the repair manual says :
The other data required is obtained
via the CAN data bus from the Controller Antilock
Brake (CAB) and the Powertrain Control Module
(PCM).
The following are CAN Bus data inputs required
for FSS indicator operation:
² CAB supplied input: 4 wheel speed signals for calculating vehicle speed
² CAB supplied input: 4 wheel speed signals for calculating distance traveled
translation : the dash module has circuitry to decode the pulse rate from the CAB to drive the needle ........
But I am probably overlooking something.
