440 Blink code diagnostic test

[walshy014]

HI, I have used the blink code diagnostic test on the volvo and it came up with a fault, long story short, the sensors fine and I was wondering if it has been replaced but the blink code thing not being reset.

I want to know the proper way of resetting the blink code tester to see if there is something wrong with the wiring or was it a solved fault a wile ago with the original owners because the blink code tester 'remembers' the fault code until its been reset.

Key at position 2
Connect to 2.
Press and hold button for about 5 seconds
Release for half second
Press and hold again for 5 seconds
Release

At the end of this procedure it will run a self test again and it will report error codes if any.

Also, when you do this you may find that the hazzards flash, wipers will do 1 or two sweeps & maybe some other lights will flash. Mine did this, It's apparently all part of said 'self-test'. It's quite amusing!
