B1193 — SRS: crash event storage full and locked

Don’t put off the repair

For makes: Chevrolet, Cadillac, GMC

Open this code in the appDownload the app

A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.

Possible causes

What you can do yourself

  1. After such a crash the airbags and pretensioners may not deploy again: don’t put off the repair.
  2. After a crash, deployed airbags and pretensioners are replaced, and the SRS unit is restored or replaced.
  3. Don’t test squibs or airbags with a multimeter and don’t take them apart: the airbag can deploy and injure you. Touch the connectors only with the battery terminal disconnected and after waiting several minutes. Don’t fit airbag “emulators”: there will be no protection in a crash.
  4. This code can’t be cleared with a scanner: the SRS unit is restored or replaced.

This is the GM meaning (Chevrolet, Cadillac, GMC). On other makes this number means something else: if your car isn’t made by GM, change the make at the top.
