PASM + airbag warning after battery disconnect

PASM + airbag warning after battery disconnect
Having replaced front dampers, removed seat and thereby disconnected the module under the driver's seat, I have a bunch of errors og suspension, PASM, airbag and instruments.
The PASM usually goes away after few seconds driving, but not this time.
I've tried to clear them with Durametric but they come back instantly.
Any thoughts before getting Mr P to look at it?

check shock plug connections
check pasm module is plugged in correctly
When disconnecting battery, the pasm error will show then clear after a few 100 ft of driving. if not, some other issue.
for clarity, did you replace with OEM shocks or aftermarket?
If you have a durametric pro make sure pasm etc are enabled (or disabled) in gateway and dash modules, etc.

Double checked connections today. They are connected correctly. PASM controller is under seat, correct?
OEM shocks, yes.
Durametric is not a pro, but it should be possible to do a steering sensor calibration, which could be the reason for these faults, but nothing really seems to happen after performing this.
I get following errors
They seem weird with the valve error, as the dampers are straight from Mr. P.
OEM shocks, yes.

so, if you reset everything, drive the car a bit, what errors are present? Can you post them?
Now, I forget, but I think PASM may require PIWIS to code, but it may be different in .1 and .2. Durametric should be able to read.
If you were just replacing shocks, i don't see why you'd be getting the error unless there is a failure in system, which comprises of the pasm module, steering angle sensor, shocks, etc.

Errors posted above.
Yeah, I don't get it either. The PASM error usually disappears after a short drive if the car has been without battery power.
Only replaced suspension hardware...

There is a procedure for this in the owners manual. You have to drive 16 mph to recalibrate the TPMS as well.
It was scary the first time, I had PASM, TPMS, Sport Mode, and other faults! This is common when the battery is disconnected.
However, I did not have the airbag or suspension valve faults. I have a stock suspension.
Good Luck!

Trace the wiring from the shock plug to the control unit. Possible you have a wire issue. Just do a basic continuity test to start. With a brand new shock it’s unlikely it is also bad. You are getting the pasm error due to the shock not communicating with the control unit. It will run in full,stiff as it is.
The sport mode error likely caused by shock fault
i suspect sas will be ok once you calibrate it.
