iveco tector 2004 75e17 edc fault 93?

I have an Iveco tector 75e17 2004 and tried starting it with a low battery and failed.I have charged the battery up and it wont start with the edc light flashing.if I press the test button it flashes 9 times slow and 3 times fast so I assume that a code 93.before this happened lorry was running perfect.thanks
