Speedo dropping out

[Yendor]

The VSS sends the signal to the instrument computer mounted in the instrument cluster. From here the signal is sent to the engine computer, auto computer and cruise control computer.

It's strange that the cruise control stops working but the auto shift isn't affected. It might be a problem with the instrument computer. Were you able to check the vehicle speed via a scan tool?

While using your fingers to twist/flick the drive you should see about 2-3 volts momentarily on AC volts on your meter.

To make it a lot easier to attach the alligator clips, I used a knife to strip a little section of both wires to connect the multimeter and will use a bit of silicon to seal them properly.

Hey mudnut that is not good practice cutting insulation of your wires it can and will cause green death get yourself some multimeter probe spoons cheap as chips saves a lot of hassles down the track Attachment 67374

These just slip in the back of the plug

Yep, have some, but most blokes don't have them. The silicon will stop any ingress of moisture if pressed into the gap.

No mate. Don't have one.
Would you say that the problem probably is in the instrument cluster?

Yeah that would be my guess. Probably not the gauge but the instrument ECU.

It sounds like the VSS is working.
