Hva betyr feilkoden?
The airbag module is supplied through two separately fused power inputs, and this code concerns input B. The code is set when the voltage stays too low for a longer period. Causes may be low battery voltage, a damaged alternator, poor contact or a short to ground in the supply wire.
Mulige årsaker
- A short-circuit to ground in the supply cable
- Contact resistance or oxidation at the connections
- Low battery voltage
- Damaged alternator
Hva du kan gjøre
- 1Have a workshop check the battery's condition and that its terminals are tight
- 2If only SRS-U300716 or SRS-U300717 is set, have a workshop start with the supply cable to the fuse box in the engine compartment
- 3Have a workshop check the alternator's charging function and the voltage supply and ground to the airbag module
- 4After the work, switch the ignition off, switch it on again and see whether the code is gone
- 5Do not work on the airbag system yourself; have a workshop carry out all wiring and control module checks
Symptomer du kan merke1
- The SRS warning light comes on or behaves abnormally
