WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
When Monitored: When the ACM is not configured for an ON - OFF switch, the ACM monitors the Passenger Airbag On - Off Switch inputs to determine if a switch is present.
Set Condition: The code will set, if the ACM detects a Passenger Airbag ON - OFF Switch connected to the Airbag Control Module.
