Instrument Cluster Programming and Setup
WARNING: This page is about a different car, the 2010 GMC Canyon and 2010 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
The odometer will read zero miles after the instrument panel cluster (IPC) is replaced. The body control module (BCM) stores the mileage information for the odometer. The vehicle will have to be driven for the BCM to send out a mileage update to the IPC. The IPC should then display the current mileage.
