Odometer Malfunction, Dashes Instead of Mileage

[Quintana's_Fiero]

I drive a 2012 Sonic LTZ, Since owning for a few years I noticed my gauge cluster got dimmer and dimmer until i could only read it at night.

I have since replaced the unit with a junkyard cluster from a 2013 Sonic RS. Shortly after installation i noticed my odometer didn't update.

After researching on moto logic i found i need to VIN match the BCM and cluster together with a SPS/MDI tool. IS there any way to spoof it??

You'd need a special tool and software access to deal with the VIN programming on the cluster. Maybe some shops can do it. The dealership can do it. Maybe some business may sell a cluster and program it too.

I can tell you a simple scan tool like a Foxwell NT510 Elite GM can't do this. It can show info like VIN, programming date, etc and has CAN bus learn. But that's it.

There are certain things that are not fully user friendly. Instrument cluster is one.
