Mk8 Ford Fiesta / Ecosport Engineering Test Mode - Instrument Cluster Hidden Test 

Welcome to a Dans Diagnostic Quick Tip Video.
Here I show you how to place a Mk8 Ford Fiesta instrument cluster into engineering test mode.
You can see in the video you can carry out a sweep test of the gauges, check the battery voltage and when the engine is started you can watch the voltage change as the alternator kicks in.
If you go through the list you will find more options such as part numbers, DTCs stored in the cluster etc
