Hello, I have a strange problem with a Fiat Punto 188 from 2001. The speedometer always shows only a quarter or a third of the real speed. I have already exchanged the following things: Tacho, ABS block, ABS sensor at the front left. I also installed the speed sensor from the Puntos without ABS and attached it to the green/grey line of the ABS connector. Here unfortunately the speedometer needle does not move. With the diagnostic software I can read everything except the ABS block. However, the ABS fuse is not broken and without the ABS block the speedometer does not react at all. What is also surprising is that the ABS lamp never concerns, even after ignition. Does someone have an idea what it might be or how I can use the speedometer signal of the gear generator alternatively? Mfg. DT
