Where is Odometer reading stored?

[Crazy Dazz]

I'm looking at an XR8 that has been tarted up a bit.
It's had a GT's instrument cluster fitted, including the odometer display. So, is it showing the car's mileage OR the donor car's mileage?

[Top_Ghia]

Cluster.
I put a new cluster in my old banged up BA wagon. It looks pretty rough for 28,000km ;)

In an AU you can just chuck another cluster in there and it will show the donor cars mileage, pretty silly you think they would store it in the ECU or BCM to stop that happening.

what happens when you need to replace ecu or bcm?
In a lot of car you can take the screen and chip out and swap them not to sure on whether you can do it to fords

I guess so.

ECU or a BCM isn't a common thing to replace though, except on E series Falcons because the solder joints crack and go dry, the BCM on those is a bad design, single layer circuit board with tonnes of crap soldered onto it. I've helped repair a few of those things.

Only certain parts of them go dry, last one was the car kept imobilising itself every now and again, it was the part of the circuit which controls smart lock, if you punched the **** out of the steering column/dash while trying to start it, it would start.

Resolder the whole board will fix it, not worth getting one from a wrecker because it will most likely have the same problem.

I've not run into problems with an E series ECU before though, its always BCM.

In a Mitsubishi, for which I have the dealer ecu tool, I can see it stored in 3 places.

The instrument cluster ( a CAN bus device), in the BCM and in the engine ECU.

In SA cab drivers were trying to "extend" their warranties a few years ago and got caught out...LOL

The Honda's I was working on in 2010 had to have new odometers set by the dealer scan tool, and it would disable the old one so it couldn't be used.

So interesting on the 380, what year is it?

years ago a mate bought a brand new Falcon wagon, think it was an XE or similar model.

he had a hidden switch installed to stop the odometer working and drove the car pretty hard and did lots of real kms on it.
the car was regularly back at the dealer getting work including a new gearbox fitted under warranty. Eventually the car was quarantined by the dealer as they suspected what he'd done.
They found the hidden switch which was behind a dashboard blanking plug and that was the end of his warranty

Silly bugger should have removed the switch before giving it to the dealer

Any different from a normal XE? I swear our one when I was a kid was at the dealer at least a dozen times for warranty issues. Which is quite bad seeing ad they only had 12 months warranty or 20,000km. Old man hated that car hahahahah

LOL haven't heard of that field service fix before.

[V8 Ghia Mike]

Mine is doing it occasionally, but only needs a light tap under the dash when turning the key.

Haha thats the EF/EL BCM fault diagnosis method, if the car turns over but wont start, but it will when you beat the **** out of the dash/steering column then dry solder joins on the BCM.

That's a bit of a worry, so I have no way of telling the real mileage of the underlying car. Pass
Not sure WHY people think sticking random FPV bits on an XR8 is "cool"?

My XR6 wagon does this but i was thinking it was a dodgy relay inside the BCM.

A good hit under the l/h side of steer column works every time.
