MINI EWS TESTING FOR NON START
MINI NON START
first of all try your spare key if you dont have one you have left it a bit late you could now spend hours checking wires and connections because of a faulty key so before you proceed GET IT TESTED
Mini ews Colours vary from vehicle to vehicle so go by pins which are marked on the plug
Test these wires first
pin 1 to starter crank engine and see if this goes live if not then go to pin 2 if that one shows power when cranking you have an ews fault. Join pins 1 and 2 together engine should now crank if not you may have a starter motor issue.
Pin 2 second starter wire in from ignition switch. crank engine and see if this goes live if not then test again at ignition switch same colour wire as pin 2
Test these wires
Pin 3 ignition live
Pin 4 data connection to ecu location on ecu dependent on ecu message reg number for ecu pinout
Pin 5 ring antenna around key pin 1
Pin 6 neutral or park switch for auto transmission
Pin 7 not used
Pin8 not used
Pin 9 earth
Pin 10 battery live
Pin 11 ignition live
Pin 12 ring antenna pin 2
Pin 13 k line to obd pin 8 on diagnostic plug
If all check out ok move on to ecu pinouts lives earths and communication wires.
