I have a problem on my Fiat Bravo 1.2, 16V, 1999, airbag type (BREED MY97 Airbag (2F-2L-S).

The warning lamp for the airbag is lighting, referring to a defective Passenger presence sensor (PPD).

I am looking for a cheep solution for this problem!



May be some one can help with a solution where it is possible to disable or emulate the defective PPD, so I can turn off the airbag light by resetting the ecu-airbagunit.
 
Hello Adrian Bravo


I have checked the airbag system using the FiatECUSan and the connector box under the passenger seat. I did not find any connection error in the plugs.

I did not measure the resistance in the PPD element, but after surfing on the www I think the PPD element has a weakness.

[FONT=&quot]Can anyone explain the technical function/type of the PPD signal (Resistance ver. Capacitance)? [/FONT]
