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.

I did some digging and found that AC-Delco sells certifications so long as you are using a proper J2354 pass thru device and their software you can reprogram the modules. The consensus is you have as many tries as you do modules.
I found out that I am missing my remote control door lock signal receiver. To reprogram that ill need that same tool and certification. So its a win win no matter what. I get to lock my doors with the key fob and fix my milage fault.

The dealer i reached out too said no anyway.

Did you know that same module for the door locks controls your TPMS. So for years that I've had the car and the tire pressure light never shut off was because my sister is a idiot.....
