Passenger Airbag Indication
Supplemental restraint system module (SRS) sends signals on the CAN-net to Central electronic module (CEM) about the airbag for passenger front is activated or not.
If Central electronic module (CEM) receives information that passenger airbag is activated, it sends signals on a directly connected cable to light warning light activated airbag passenger (PAE) (1).
It works in the same way if Central electronic module (CEM) receives information that the passenger airbag is deactivated, but then the signal to light the warning light airbag passenger (PAD) (2) is sent.
The lights are located in the overhead panel. Each light is on until Central electronic module (CEM) receives information that status of the passenger airbag has been changed.
Depending on the market, if the switch for activating and deactivating the front passenger airbag is used to deactivate it, the passenger airbag disconnected (PAD) warning lamp lights.
The warning light goes off when the airbag is activated again and then warning light activated passenger (PAE) is lit instead.
If an occupant weight sensor (OWS) is installed (market-dependent), the passenger airbag warning light (PAD) lights when the airbag is deactivated.
The warning lamp goes out when the airbag is enabled.
If Occupant weight sensor (OWS) is installed, there is no warning light activated airbag passenger (PAE) installed.
Reason the passenger airbag warning lamp (PAD) lights could also be:
- communication problems between the supplemental restraint system module (SRS) and central electronic module (CEM)
- faulty function in the on/off switch for the front passenger airbag
- defective occupant weight sensor (OWS) function.
