Thanks to RumRunner back in 2012. I had the same issue where I had errors displayed below as well as a "X" in the Aircon display (represented below but later with a picture editor as forgot to take a picture. Anyway replaced ABS Solenoid Pack reconditioned for around $300 in comparison to $1000 from Holden (or whats left of it).
Other symptoms where:-
1) ABS and TRAC OFF. Otherwise car drove fine.
2) When it occurred sometimes turning it off and starting it again cleared alarms.
3) Only one time my ABS fired as if I was braking at high speed and losing grip but was only doing 20-30kms driving like a grandpa... So should not have fired.
4) A little "Tune" played with 7 notes when it happened.
Hope it helps someone else.
