Titel: 60 to 20 to 60 in 1 second
Bericht door: Barry_C70 op 20-11-2006 13:43:47
So today I was driving home from class and suddenly my speedometer drops from 60 to 20 in like 1/2 a second and then straight back up to 60 again, I would have missed it if I wasn't looking down for that brief moment.

I'm guessing it might be because of how wet the roads are so maybe there was some wheels speed instantly corrected by TRACS, but I would have thought that with wheels spin, the speedometer would register a HIGHER speed? but isn't speed measured from the rear wheels?

I didn't feel any change in speed or momentum at all either, ideas? Is this a telltale sign of something bad? I haven't had my ABS module fixed yet either if that's an issue.

Kan een relais zijn. Even alle relais aandrukken kan helpen.

Of een "glitch' in je ABS controller. Als je de ABS-unit namelijk demonteert valt je snelheidsmeter ook uit.
