Hello,

This question has been evocated a lot of times but a friend has installed a HUD cluster and the current mileage is lower than the original.
I'd read that it is possible with a the Tech2 to update this info.
I did a search here and on the web but found nothing
My friend has a Tech 2 but doesn't know how to perform this modification
Here in France it's very difficult to find a Chevy dealer able to do that....
I know that question is very "hot" in the US due to the law. But if someone could send me the process in pm it will be very nice.
Thanks guys

DADAROO, mr sam can help U, I have seen him post info on this many times

jmz06

Hi Bjones,
thanks for your answer

I read several post wrote by Dadaroo, but I didn't dare to send him a pm
Should I try ?

Absolutely... great guy... he'll help you anyway he can

jmz06

Ok, done
thanks

I'm pretty sure that a Tech2 can't do it.

jmz06

A Tech 2 + tis maybe ?

LoneStarFRC

I definitely think this is something only a dealer can perform.

lionelhutz

Cluster repair shops can typically do it. Or try to find someone who "fixes" (in reality turns back) the mileage on vehicles. That one would depend on your plate licensing tracking the mileage or not. Here they do so it's not common but next door Quebec doesn't and it's fairly easy to find someone to change mileage there.

I thought a Tech 2 could do it but I talked to Bill Curlee and he did not think it could. There is path in the Tech 2 that indicated it "might" do it. I told him I would try it as he had not seen that path. Have not had time to try it but will soon. My car is away at one of my warehouses.


Mr. Sam

PS: I always welcome PMs, I must get 6 or so each week. I don't bite. Does anybody remember the line from the Pink Panther when Inspector Clouseau asked "does your dog bite?"

Don't try the method used in Ferris Bueller's Day Off if anyone needs to run it back.

I found this Tech 2 pdf

http://fr.slideshare.net/obd2motor/u...mmming-scanner

page 8-47, Odometer reset > Special Functions / Engine Ouput Controls, Odometer Reading > Instrument Panel Cluster / Special Functions

But it is not possible to change anything (only with Tech 2)

LoneStarFRC

Indeed! CLASSIC Peter Sellers.

dadaroo

That is what I was talking about. Of course you have to use a Tech 2 to do anything in that list. Why has he not tried it?

jmz06

He tried but it is not possible to change or reset the mileage.
The mileage is displayed and that's it...
This why I guess that only a Tech 2. Is not is only tool needed.

dadaroo

I'll try on my car when I get a chance and see if I can.

KoreaJon

LOL! That's one of my all-time favorites!

"No."

The man reaches out, the dog bites him, he exclaims "I thought you said your dog doesn't bite!!"

Clouseau replies "It not ma dog!"

The function in the TECH 2 can not change the mileage. A certified odometer shop that has the correct interface can do it.

If,,,,,,,,,,, they are a legit business, they will require a LOT of documents and paperwork to perform the mileage adjustment.

I found this TSB, not applicable for Corvette but as Bill says, only a tech 2 is not enough
I guess the process for a Corvette should be similar
Bulletin No.: 07-08-49-015D

Date: May 04, 2010

Subject: Information on Instrument Panel Cluster (IPC) Odometer and Engine Hour Meter Set Up at Dealership After IPC Replacement
Models:
2004-2007 Buick Rainier
2003-2006 Cadillac Escalade Models
2002-2009 Chevrolet TrailBlazer
2003-2006 Chevrolet Avalanche, Silverado, Suburban, Tahoe

2005-2009 Saab 9-7X
Attention:
The purpose of this bulletin is to inform dealership personnel that the Instrument Panel Cluster (IPC) odometer and engine hour meter (when applicable) setting will no longer be performed at an Electronic Service Center (ESC). Dealerships will now receive IPCs with the odometer and engine hour meter not programmed. The technician will be required to note the odometer reading and engine hour (when applicable) values of the original IPC, then use the SPS application to program these values into the new IPC.
Supercede:
This bulletin is being revised to update the text in Steps 1, 2, 3, 4, 5, 6 and 7. Please discard Corporate Bulletin Number 07-08-49-015C (Section 08 - Body and Accessories).

Background Information

Previous IPC replacement procedures specify that the odometer and engine hour values be communicated to and programmed by the Electronic Service Centers (ESC) into the replacement IPC at the time the replacement is ordered. This required the vehicle to be parked after the replacement IPC is ordered so that no additional mileage can be accumulated on the vehicle while the new IPC is in transit to the dealership. Improvements to the TIS2WEB SPS application will now allow IPC odometer and engine hour programming to be performed as an additional function of the IPC programming event. This new process will allow the vehicle to be returned to the customer, if necessary, and driven while waiting for the replacement IPC to arrive at the dealership. Odometer and engine hour values will no longer be communicated to the ESC for programming purposes but ESCs still need the odometer value for warranty reporting. Dealerships will now receive a replacement IPC with the odometer and engine hour values NOT programmed. The technician will be required to note the odometer and engine hour values of the original IPC, then use the TIS2WEB SPS application to program these values into the replacement IPC. The odometer and engine hour programming will now be included as a normal part of the IPC replacement procedure in SI.

Odometer and Engine Hour Programming Procedure Information
-If the original IPC odometer value cannot be obtained from the customer's vehicle, follow local and federal regulations regarding unknown odometer mileage situations.
-Because the odometer and engine hour values can now be read from the original IPC and programmed into the replacement IPC during the same visit, the customer's vehicle will no longer need to be parked until the replacement IPC is received from an ESC.
-Avalanche, Escalade, Sierra, Silverado, H2, Suburban, Tahoe and Yukon vehicles will also require the engine hour data to be recorded for transfer to the replacement IPC. The replacement IPC may already have engine hours showing. This does not affect the IPC Setup procedure. Bravada, Envoy, Rainier and TrailBlazer vehicles do not support the calculation or display of engine hour data.
-Ensure that the correct odometer value is entered when prompted. Once programming is complete, the odometer and engine hour values, when applicable cannot be changed.
-By default, the application odometer entry will be set to: miles. For metric units, click the button on the left next to: Kilometers.


Service Procedure
Important
The replacement IPC requires IPC Setup procedures and SPS programming to be performed. Legacy Pass-Thru will no longer be supported, only J2534.



1. BEFORE the original IPC is disconnected from the vehicle, record the odometer and engine hour values.

2. Replace the IPC with a replacement part obtained from the ESC. Refer to Instrument Cluster Replacement in SI.

3. Using the TIS2WEB SPS application, select either: J2534 Tech 2 or J2534 MDI, when available and build the vehicle.

4. Select: IPC Setup J2534.

5. After selecting IPC Setup J2534, the user will be prompted to: install the new controller. Ignore this prompt if the new IPC was already installed. This prompt is just to remind the user that this application is only for a new IPC.

Important
FOR 2003 FULLSIZE TRUCKS, UTILITIES AND H2, THE ENGINE MUST BE STARTED AND RUNNING PRIOR TO ENTERING THE MILEAGE AND ENGINE HOURS. After the odometer value is programmed, the engine must remain running for 6 minutes 15 seconds before the ignition can be turned off. Failure to do so will result in engine hours not being programmed and a new IPC will have to be ordered.

6. Enter the odometer and engine hour values, when applicable. By default the application will be set to miles. For metric units, click the button on the left next to: Kilometers. The IPC odometer and engine hour meter setup procedure is now complete.

7. The IPC calibration files can now be programmed into the IPC. Refer to SPS in SI

You would have to think it would not be as easy as just having a Tech II - otherwise way too many people could change the mileage.

lionelhutz

That info above says that it only works for a new cluster. I'm quite certain a dealer can't change the mileage on a used cluster.
