Does anyone have a pic of the 05 IPC circuit board where the mileage chip is. I need to swap it with the one in the used cluster.

 

I've attached pics of a C5 Z06 IPC board. I'm not sure if the C6 cluster has the same configuration. If not, then the mileage can be changed using a TECH II I believe.
I do know that USSpeedo will change the mileage on used units to match the vehicle mileage.

In the C5, the odometer "memory" is stored in a module in the gauge cluster. You can actually swap the odometer module between the two gauge clusters to keep your existing odometer reading.
Here is what the module looks like
Here are the C5 IPC


and here is a shot of taking it out.

 

I called 3 dealers they all said I had to leave the vehicle there and they would order a used programmed IPC and put it in , this would cost a fortune to have them do it . Only one acknowledged you can use a tech2 or MDI . My tech2 paths shows odometer reset but won't connect to my laptop with TIS2000. I'm wondering if it's worth the trouble it's an 05 and I intend to keep it. If I could find which chip it is I might try the quick chip way of swapping it.
Thanks for your help I appreciate it .

 

A/C Delco, has to write a special VIC file, then it pulled during SPS to flash in the correct mileage. The glitch, A/C Delco only trust the dealers to do this (pull the actual mileage and give it to them as they are writing the file, then flash it in before the actual mileage changes at all), so will not write the specal file for anyone one else.
Note, as you go to use SPS, you have the option of using the normal files for the car, or in the case of IPC mileage reflash, VIC file that SPS will pull down instead.

Short of SPS, their are other methods to change the mileage in a IPC.

So if you talk to US speedo, may just have to use a Tech II to pull the actual mileage from the BCM/ECM like a dealer would, take a screen shot of it and send your replacement IPC and screen shot of the actual miles in instead. To add, there are other shops that have a way of cracking the board as well to mileage flash, and lets just say don't give a dam what mileage they flash in. The glitch since the mileage is stored in a few modules, first time dealer goes to check the mileage between the area and it does not jive, such is going to show up on a GM service history report to ding the hell out of the resale value of the car.

So really, what you want it to be able to install the IPC, dive the car somewhere so when the IPC is flashed, it's flashed to the actual mileage of the car that is located in the other modules at the time of the flash. Us speedo can do the flash to correct the IPC mileage, but keep in mind, until you get the IPC back to re-install the car, don't move the car an inch.

 

We need a ‘ask Dano’ section of the forum. Crazy amount of information available.

 

Hell, most of the time when an IPC does have a problem, it just a cold solder joint on one of the pin headers. Hell, have seen the same problems in RCDLR and SCLM when the cars are driven on rough roads, which breaks the cold solder joints free even faster than normal.

Bottom line here, since the boards are produced in a solder bath, the problem with the header pins since they have more metal to them, they absorb the heat that would normaly create a good solder joint on smaller pins during a bath process instead. The craptasitic cold solder joint may be good enough to pass the QC check when the board is new for a function test, but a little rough road driving, and the cold solder joints rear their ugly head instead.

So since you have to take the IPC out anyways to start with, just open up the IPC to get the board, and give it a quick once over on the solder joints. If you can solve the cold solder joint/corroded ribbon pin problem, then all is good with the world and you don't have to go down the rabbit hole of trying to find someone to flash your actual mileage in the replacement IPC and install it, as the car sits in the same spot, since the correct mileage is already correct on the board.

And the funny part since Dealers are the only one that can get the VIC file written (which only takes a min during the phone call), by the time they pull the mileage from the other modules, call it in to get the VIC file number at the same time of the call, it only takes about 4 mins total from time of start to finish of flash. Hence VIC file is pretty much complete to start with, and A/C delco just has to add the vin number and mileage amount to that file, do a quick save as so its in there system under a given VIC number, and SPS pulls it down via the VIC number to flash it in.


Hell at one time, you could go to any A/C delco speedo shop to have an self installed IPC replacement flashed to the correct mileage, but that was decades ago, before it all become a "Trusted" dealer service shop item instead. And the funny one, if you do a BCM or ECM replacement and reflash, the normal method of flash will pull the mileage from the other units at the time of flash to get them correct. Its just the IPC flash that does not do this, and requires the special VIC file to be written to get it mileage correct instead.

 

Thanks alot I appreciate the information. I might just leave it. I intend to keep the car.
