- Press and hold the left scroll wheel on the steering wheel.
- Whist holding the scroll wheel, turn the keys to the ON position (You can also start the car if you choose to do so)
- Once the system check has completed, let go of the scroll wheel
- You are now in Engineering Mode!

There are many different line items to be found in Engineering Mode. You can scroll through these by using the left scroll wheel
Version number instrument cluster
GM Part Number
Part No. of the instrument cluster
Shows the current voltage from the battery
Shows the current charge of the battery.
Note: This will never show 100%, and could show a false figure. It may say 60% charge however the car won’t actually start.

This will activate a test mode within the cluster, where all LEDs will turn on, tachometers centred and the speaker will emit a constant beep. This is used to ensure everything is working correctly
