B1BB6 Description

 

When the ignition is on, the Passenger Airbag MUX Switch Sense circuit supplies a 3 to 10 ms pulse every 100 ms across the On or Off switch resister to the Passenger Airbag MUX switch return circuit. Once the code is active, the Occupant Restraint Controller (ORC) will disable the indicator for the duration of the ignition cycle. The code will set if the ORC senses constant voltage over approximately 4.0 volts on the Passenger Airbag MUX Switch circuits.
