Odometer Reading
Some time ago, I posted about an imported '92 Vette from Japan. On Sat., I went to see if they would accept my offer before winter sets in.(They wouldn't) Anyways, they had another '92 there that they said had only 35,000 kms. on it. The salesman first said it was a '93 until I informed him that by the serial number, it was a '92. The funny thing was, it had chrome factory wheels which I don't believe were available in '92.(please correct me if I'm wrong.) I checked it out close and if that car has only 35,000 kms. on it, I will eat it piece by piece. I don't know about the U.S., but in Canada, if you get caught altering mileage on a car, you get slapped pretty hard. However, what if it's done in Japan and then the car is brought over? I don't know. My question is; is the acual mileage stored anywhere in the computer and if it is, how can it be read. Thanks.

I believe that it is stored electronically. Probably take a dealer to retrieve the data.
About the car itself; it's possible to beat a car up in very few miles (or kilos).

The odometer mileage can be reset by replacing the computer but LEGALLY they must attach a tag to the driver side door post stating the total original miles on the odometer. Mileage is really hard to estimate as mine has over 94K and looks like it has 10K, whereas some with 10-15K look like they have 100K.

Silver is so right. I had a '91 with 110k on it and folks had a hard time believing it had more then 20k on it. I kept it really nice.
I have seen cars with 30k and look like they have 100+k on them. So the car that says it has 30k on it could be actual. Because it didn't have caring owner!

I beleive in Japan there are heavy fees for owning a car with an engine over 30k, could be right, I was told thats why there's a lot of imported used engines from japan for imported cars.

My car has just under 40k on it right now, and looks like it has 100k. Exterior isn't horrible, but my seats look like they were used in a "How bad can we get them?" competition.

My vette has about 70K on it...
I consider that to be pretty low mileage for an 85.
It looks about like a 20 year old car should look, with that many miles...
after I'm done I'm hoping it'll look like its got about 2K on it
my daily driver has 221K on it... It looks good, looks like it barely has an inch over 210K

If this is so, them I'm in the wrong gig. I'm moving to Japan and opening an engine swap-shop.

computers can be bought from a low mileage wreck or adjusted by any crook with the tool.you really gotta analyze what your seeing on late model cars,not only telltale condition but also the people who are selling,why they are selling,who owned it before,why they sold it,check carfax....
all these things.its really not any harder to alter the odometers now than it ever was.it just takes a geekier crook than it used to.
once a friend of mine bought a low mileage 70 gtx,nice car but we found 3 burned up cheap craftsman reversible drills in the trunk
lol,we knew what that was about.
thats intereting about the japan info.did not know that.

Mileage CANNOT be alter via used computer from wrecked car. Both the PCM and CCM must be replaced and programed together to match in sequence by gm tech 2 computer within one hundred miles of replacement or engine will shut down and you get error code. Both PCM and CCM must be matched and old data downloaded from old boxes for them to work. You can count on 1990+ vettes with digital mileage to be accurate 99.999% of the time.

instruction manuals included.
odometer fraud is huge today.almost a half million cases this year.

The CCM in later cars (my 92 has a CCM -- Central Control Module as stated in the factory service manual) has the VIN loaded to that module. A Tech 2 can display the VIN and then its a simple match to the sticker in the corner of the windshield.
When a new CCM is installed, it must be programmed with the proper mileage reading within 100 miles or it will no longer accept input for an odometer reading. And programming for odometer readings are only in 6-mile increments. I don't think it will kill the motor.
A CCM from another vehicle may not provide the proper codes when there are problems with systems that may not be in the car a used CCM is installed in.

heh,yea its like staring into a bowl of alphabet soup with a hangover when your trying to fix these elctronics woes nowdays.our monitor at work isnt real intuitive (older moniter4000 enhanced).it spits out a bunch of letters then you gotta research to see what they are talking about. think they do it on purpose arg.
one thing thats kinda funky here is all the info thats available through gmfleet or the actual oem manuals will give you info on installing NEW gm components but they dont offer any input on swapping used parts around.
im betting its a hit and miss thing.sometimes it may work fine and other combos wont even run.(there was a thread here last year a guy had the computer out of his van in his vette)
so,with these bi-directional tech2's,couldnt a scoundrel simply toggle the mileage reading to whatever he wanted it to say?ive often wondered that because if thats the case they wouldnt even have to change out any hardware.

try a google search for "odometer fraud". it s pretty spooky but theres lots of tips on how to spot it on a used vehicle.
example:http://www.ehow.com/how_17709_avoid-odometer-fraud.html
as far as once its been altered on a vehicle i dont know if you could pull the old mileage out of the computer or not.
