Code B1884 Ford Description

When the ignition is in the ON position, the Passenger Air Bag Deactivation (PAD) indicator prove-out period is initiated by the Restraints Control Module (RCM). The RCM briefly activates the PAD indicator to verify the occupants correct functional operation of the PAD indicator. For additional information, refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS). If the RCM detects an open or short to ground on the PAD indicator circuit, it will store the Diagnostic Trouble Code (DTC) B1884 in memory and illuminate the air bag warning indicator.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
