Ecu fault code (2 flashes) C20XE

[TWAG]

Wired up ecu light today and it come up whilst driving, i grounded the plug to identifie the code and the ecu light flashed twice.

Does any one know what this code means?

12 Initiation of diagnosis. n/a

Thats the only one i can think it would be

if it only flashes on briefly wen not pluged/wired in diagnostic mode it more than likely means nuthin.
in the orginal manual (nova one anyway) it said that if the ecu light cums on momenteraly (sp) it is of no consequence. only panic if it stays on for longer than a few seconds. if it did then u need to bridge to the connectors/pics, not ground them...
