No ...but my theory is it gets flagged every time the car stalled whilst in motion and in gear....
I ended up cleaning all the dfi module pins and sockets same with the cas, the car was fine up till it was rear ended and written off in late 2018

Mine turned out to be the crank angle sensor code but had to update software to read the code. It's running again but I have a vibration in the car that seems to be getting worse and have exhausted all avenues trying to fix. Starting to wonder if it's the balancer. Funny thing i got rear ended start of 2019 and my old vx was written off.

I bought a genuine CAS to have as a spare over a decade ago and I've not had to ever replace a CAS on a V6 commodore since it's been on the shelf in my garage :)

I did the same, and its still sitting there.

I would suggest the issue is the DFI harness plug terminal tension if all other components have checked ok.

Very painfull time consuming job. whats needed is each and every wire terminal has to be checked and if terminal tension is loose, released/backed out of the DFI connector, the terminal contact VERY carefully pushed with a tiny small tool (needle/pin) so as it make proper contact with the DFI module terminal.

Though, even this may not completely rectify the issue as the terminal retention clips in the actual engine harness DFI plug could be worn from plugging and unplugging of this connector.

Ideally you need a new DFI harness connector pigtail.

They are still available.
