Double Air Bag Fault Code Stored

[wayne1234]

Morning All,

I've recently bought a CAt D 3 series which was involved in a accident. I've replaced everything required to clear the faults.

But I'm left with the 93B5 code displayed twice on my diagnostic scanner. (See Attachment).

Has anyone had this type of issue before?

I have no other codes within the Air Bag Module.

Cheers

Hi Wayne

If the pre-tensioners were fired in the accident then I believe they need replacement before you can clear the code. If they have been replaced then you may need a BMW specific reader to reset everything.

Hi Dave,

 

Thanks for your reply.

Yes the tensioners  have been replaced. I've also replaced the rear right too. this code cleared with no issues. I've tested the new left unit which is also fine.

Morning Wayne

Well that's narrowed it down some, thinking out loud have you checked the loom and plugs clean them with contact cleaner. Don't ignore the earth I suffered many strange malfunctions and eventually tracked it to a poor earth connection in the boot. I could only clear codes by clearing individual modules if I tried to clear them by hitting the clear DTC button it never worked, some would clear others not. Final thing the battery needs to be tip/top if it's down at all it doesn't help.

Much appreciated
