C30 SRS-CFFF Control Module Internal Fault- reinstall experiences?

[anacortesian]

Initial issue: Had an older battery with low cranking amps. Waiting to long to replace - dead battery one morning. No jump start - just replacing with new battery. Next day - urgent service light on. Talk about sensitive electronics...makes you wonder if the battery were properly replaced when first deemed low...if that too may trigger the urgent service light...
...Anyway, after removing the SRS module under the console, sending it to Crash-Data UK to get the CFFF code cleared (with no warranty by the way) and waiting 7 weeks to get it back (Corona Virus and UK Customs). I'm now about to reinstall and just wanted to check one last time with anyone who has experienced this issue and their reinstall experience. I think the basics are: Connect the positive cable first, then the negative on your NEW BATTERY. Then place the ignition key. Wait for 20min before tuning the key (for the cars elect. system to store info to the modules). Then start the car and hope for the best...Do I have this sequence right? Just wondering if I might be missing anything here?

Yes sounds like a resonable installation plan. You don't have to wait any 20 minutes. But make sure when you turn the key to position 2 that you place your arm in front of the steering wheel (standing outside). If not under the very unlikely case if the airbag pops it might break your arm

Interesting precaution. Thanks 3r1k.
