Working on some other stuff on my 5th and figured I might as well fix the CC. It was working before the last rebuild when I swapped in a tranny. Not wirkng now. Will do the diagnostics to see if something is cancelling but will focus on the VSS first.
I have 4 of them, One the original that failed a while back. I want to run a diagnostic on each of them (rather than swapping them and testing them , painful).
From the FSM, it's a 3 wire system. But nothing on the Internals. Guessing 1 pair is a 12v circuit and the 3rd wire is a either a control signal or a return signal from/to the CC computer.
The electronics are not wrapped around the speedometer cable, just clamped to the side. Mechanically, the speedometer cable likely spins a magnet/iron than induces a electromagnetic signal on the 3 wire setup causing some sort of change in the signal.
Anyone ever bench test one of these? How?
