What does this fault code mean?
The airbag control module has found an implausible signal in its own main software. The fault is algorithm based, meaning the module's program has reacted to values that do not add up, and it comes from faulty software.
Possible causes
- Faulty software in the airbag control module
What you can do
- 1Erase the code with a diagnostic tool, switch the ignition off for a while and on again to see whether it returns
- 2Have a workshop download new software into the airbag control module
- 3If the fault remains after programming, have a workshop replace the module
- 4Do not work on the airbag system yourself; have a workshop carry out all work on the module
Symptoms you may notice2
