The Citroen C3 passenger air bag switch found on 2002 to 2009

Is operated by the ignition key between ON and OFF to disable or enable the passenger airbag.

The resistance measurements of the 2 pins on the switch are shown below.



Zero ohms in the OFF position (0.7)
Zero ohms in the OFF position (0.7)
The switch in the off position shows .7ohms which is very close to the .6ohms of the meter leads, so is effectively a short circuit at zero ohms.


0.4k ohms in the ON position
0.4k ohms in the ON position
0.4K ohms is read while the switch is in the ON position.
