VS SS Commodore 1996 Speedo not working

[Immortality]

UPDATE- Just got my car back from auto Electrician, as mentioned earlier, Speedo cluster repaired as it was faulty,
Speedo sensor also replaced as it was faulty. All wiring checked, the Pins of the Plugs cluster goes into checked are all good.

He's convinced it's the ECU that's the issue, also mentioned a week earlier he had a VS 5L Calais come in and his Diagnostic scanner worked with that car and he was able to clear codes.

When he plugs his diagnostic scanner into my car it does not communicate with it, next step is finding an ECU I guess.

I'm in Adelaide, iv looked around and can't find anything.

Well that certainly does point to the ecu having a problem.

It's not a guarantee that is the issue but the likely culprit.

Im wondering will a VR 5L ECU work in a VS 5L series 2? My car is a VS SS series 2

Iv been told they are the same, any help appreciated, cheers

I'll add the ECU from my car has the 2 blue plugs and the one Im looking at has the 2 Blue plugs, also has the same service number at the top.

As long as the service numbers match it should be fine. (382 or 424 I think are the common ones for these models)

You may have to swap the memcal however.

No coms with the ECU isn’t always a faulty ECU.

If those things were not working it would go into limp mode or very least intermittent fault.


Why do you need scanner when thin piece of wire all you need to check codes?

I think the OP was looking for higher level diagnostics than the paperclip can provide by using a Snapon or similar to test things.

obd1 is like commodore64 to a new laptop.

Most likely scanner could not link to something archaic prooobably obd2 onwards like most scanners.

If you've ever looked up all fault codes you're underestimating power of the paper clip & google or forum search lol

There isint really higher level diagnostics. These are dinosaurs in every way and the paperclip really is what works for most efforts. Multimeter and then the old parts swap is what’s left.

While I agree there are limitations on what can be done. There is still some functions a Snapon can perform that a paperclip can't, even on these old PCMs.
