Intermittent Speedo and Odometer

[Thom]

Hey guys,

I have an issue where when my Legnum has been sitting in the sun on a hot day, the speedo / odometer don’t work (but tacho does).

The dash illumination etc all continues to work.

Once the ambient temperature cools down it suddenly starts working.

I’ve checked the vss plug and all fuses and they seem fine, I’m thrown off that it’s intermittent.

Any ideas?

Do you have an aftermarket stereo?

Help:>> After Stereo install Speedo not Working

Hi All, Has anyone experienced after having stereo installed speedo stop working correctly, ie. when stereo is turned up above half volume the speedo needle starts dancing, the louder you go the faster you go (according to the speedo i was just doing 180kph in my driveway) The stereo was wired...

Hey Thorn,

I have an intermittent speedo issue that I have not attributed to temperature. It comes and goes, sometimes, but rarely within a drive cycle. I've tried changing VSS with one I thought was compatible but it made the speed read double.

What I also figured out is when the VSS is straight up unplugged, the transmission also gets pissed. That seems to indicate the issue is on the instrumentation cluster/associated wiring .

I have an aftermarket stereo but I think I didn't connect it to the speed signal wire because I didn't need those functions.
