Software Version
Version number instrument cluster

GM Part Number
Part No. of the instrument cluster

Switch Voltage
This is the voltage measured off the steering wheel controls (Used for fault checking)

Current Gear
This will say ‘Unknown’ in manual vehicles

    Hi guys I really need some help I have a Ve 2009 wagon and I took the battery out 3 months ago, now I am trying to start it and have a dash light of a car with a padlock over the car on my dash. I also have no power gettin through when I turn the ignition.

    My VE shudders when idle at red lights, I’m taking it in to get checked, but is there any way of looking in engineering mode to maybe figure out myself what’s wrong instead of trusting a mechanic to find the reason and then maybe trying to swindle me out of more cash??
