If it flashs code 12 this is a hard fault and you will probably find the fuse blown.
Go to the Data Link Connector next to the fuse panel....
find a piece of wire 100mm long (bare ends)
igniton to ACC
Top row ... 4th from left = Air Bag Clear
Bottom row... 3rd from left = Ground
having connected these two pins for a few seconds
(must have GOOD CONNECTION... not easy)
you will hear 5 quick BEEPS... then remove wire...
check for any new codes....
(PROBLEM NEEDS TO BE FIXED BEFORE CODE CAN BE CLEARED)
repeat above if necessary
No responsibility taken if you miss the required pin and blow something up
