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
- There was a crash and the airbags or pretensioners deployed
- The SRS unit after a crash: it must be restored or replaced
What you can do yourself
- You can drive, but don’t put off the repair: the airbags may not deploy in a crash.
- 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.
- After a crash, deployed airbags and pretensioners are replaced, and the SRS unit is restored or replaced.
- A crash code does not clear: after the airbags deploy, the SRS unit is replaced or restored.
This is the Hyundai and Kia meaning. On other makes this number means something else: if your car isn’t a Hyundai or Kia, change the make at the top.
