Airbag light on: Internal control-unit fault - replacement modules s0180 error

[cruicka]

After water penetration I got the dreaded red airbag light on.

Insta+ reported "93D7 ACSM: Internal control-unit fault".

After installing an identical replacement Insta+ reported "S0180 No communication possible with: Safety module/ restraint system".

Assuming the replacement module was faulty, I installed another identical one , only to have Insta+ report "S0180 No communication possible with: Safety module/ restraint system" again.

I reinstalled the original module and Insta+ reported "93D7 ACSM: Internal control-unit fault".

So, another replacement sourced and installed only for Insta+ to report "S0180 No communication possible with: Safety module/ restraint system" again!

I find it hard to believe that I have received 3x replacement control units each with the same fault, albeit provided by the supplier, however by re-installing the original unit and re-confirming the original fault that is what the evidence implies.

Anybody had this experience or any ideas what could be going on?

Does the unit need to be coded to the car?

Does the unit need to be coded to the car?

Yes, it will need the VIN and the system timing programmed, however the "S0180 No communication possible with: Safety module/ restraint system" error means I cannot communicate with the replacement module to programme it.

I have checked every single fuse, since the S0180 error suggests it could be a power issue, but the fuses are all okay, plus when I put the original module back in I can communicate with it no problem.

Given it's the same issue with every one you've tried, could it be that you need more capable software to sort it?
Just brainstorming really, as it's not my field of expertise at all.

The fact that I can communicate with the original module, without issue, would suggest the software is adequate.

Over to one of the other members with more software nous than me then............... good luck, hope you get it sorted.
