YukonOwner22 Posted May 27, 2010 Share Posted May 27, 2010 I recently was having an intermittent problem with the Instrument Panel Cluster in my 2003 GMC Yukon. It would not display sometimes on startup, would take 10-20 seconds to come on. We took it to the dealer, who tested it and said "the IP Cluster intermittently will not display." They said they inspected it and found an "internal failure with the instrument panel cluster." They said they replaced the IPC ($350). Picked up the car and the odometer reading is different by more than 20,000 miles. So, does this mean they changed the odometer? Or, did they put a used board in? Not sure where to go from here, but something sure isn't right. Any suggestions? Link to comment Share on other sites More sharing options...
sc4808 Posted May 27, 2010 Share Posted May 27, 2010 This is a tough question to answer, first off, a couple of questions, is the odometer reading 20,000 lower than before or 20,000 higher than before and did the dealer place a decal (usually on the door jam) that says something like "ODOMETER DISCREPENCY". If you have the "STICKER" then the value of your truck just dropped tremendously. If you have no sticker and the new cluster is reading 20,000 lower than when you took it in, then you will have a moral decision to make when you sell the truck since the mileage is only stored in the cluster on that year model and not in the computer, it would be up to you to let the future owner know that the truck has 20,000 more miles on it than the odometer shows. That would be your call. If you have no sticker and the odometer is reading 20,000 higher then the value of your truck has dropped but not by a huge amount. If I had to guess, I would bet that if you look around you will find a "ODOMETER DISCREPENCY" decal and that really sucks, if you had posted on here before taking it to the dealer we could have walked you through the cluster swap, it only takes 20 minutes or so to do and clusters are availible on EBay. Oh and the dealer could have reprogrammed the new cluster to show the same mileage as the old cluster but they still normally put the sticker on (and put the info in the vehicle history report that will show up on carfax so pealing the decal off won't help) due to the fact that if you were having cluster problems when you took the truck in then chances are that your odometer was already off ever so slightly and thus would warrent the "DECAL" anyway. One more thing, the reason the dealers don't take any chances, and you should not either, is because there is a $5000.00 fine for tampering with a vehicles odometer, the decal that says "ODOMETER DISCREPENCY" relieves them of that liability. Hope this helps. Link to comment Share on other sites More sharing options...

Most dealerships don't even have the capability to reprogram the odometer/hour readings and usually they send the clusters off to an authorized repair station to have it done.

Please discard Corporate Bulletin Number 07-08-49-020A (Section 08 -- Body & Accessories). -------------------------------------------------------------------------------- The purpose of this bulletin is to provide a reference guide to help identify which season odometer programming method to use after replacing the Instrument Panel Cluster (IPC). The three season odometer programming methods in use today are listed below. In addition, this reference guide lists the component where the season odometer value is stored. The season odometer value may be stored in the IPC, the Driver Information Center (DIC), or the Integrated Body Control Module (IBCM), also commonly called a Body Control Module (BCM). Season Odometer Programming Methods In Use Today IPC reprogramming and setup using the Service Programming System (SPS). Odometer setup at the Electronic Service Center (ESC) when using an exchange IPC/DIC. Tech2® -- The Tech2 is used to setup a replacement BCM, which includes loading the odometer value that is displayed and stored in the IPC. A replacement IPC will display the previously stored vehicle odometer value, communicated from the BCM, after cycling the ignition or driving the vehicle.

sc4808 Posted May 27, 2010 Share Posted May 27, 2010 Great info, that confirms that the Odometer value is only stored in the Instrument Panel Cluster on these trucks, that is not very secure is it, a person could put 200K on one of these trucks and then put a used cluster showing 70K and get a lot more at trade in time, makes a person leary about buying a used GM truck.

limpalong Posted May 28, 2010 Share Posted May 28, 2010 Dealer replaced instrument cluster in my 2004 at about 107.000 miles. When I picked the truck up, the odometer read exactly what it did when I dropped off the vehicle. Today, another Chevy dealer replaced the instrument cluster in my 2008. 32,000 +/- miles. Took them all of about 50 minutes to make the switch and, again, the odometer in the new cluster was set exactly to what the truck had on it when I arrived at the dealer. Two dealers... two trucks... two clusters... both set at the exact mileage of the faulty clusters that were removed. Link to comment Share on other sites More sharing options...
