Hva betyr feilkoden?
The fault code means that the control module storing the fault does not get a working link to the airbag control module (SRS), or the link is disturbed. The airbag warning lamp may light, and the system is safety critical. The fault should therefore be checked by a workshop.
Mulige årsaker
- Missing power supply to the airbag control module (SRS)
- Broken ground wire to the airbag control module
- Poor contact in the connections
- Open or shorted CAN wiring
- A module not intended for the car, such as a used unit with other software or hardware
Hva du kan gjøre
- 1Read the fault codes in all control modules and note them for the workshop
- 2Check that the battery is in good condition and its terminals are tight, since weak voltage can cause airbag false warnings
- 3Do not carry out your own work on the airbag system, even if a loose plug seems to be the cause
- 4With a diagnostic tool, check whether the module responds, without clearing anything in the system
- 5Safety: have a workshop check the airbag wiring and ground connection. Replace the CEM only if testing has shown it is damaged
Symptomer du kan merke1
