Code B1892 Lincoln Description

The air bag indicator is designed to illuminate for 6 (Â±2) seconds when the ignition switch is turned to the RUN position. This initial 6 seconds of illumination is considered the normal operation and is called Prove-Out of the air bag indicator. The air bag indicator is then used to warn the driver that there is a fault in the air bag Supplemental Restraint System (SRS). The air bag Restraint Control Module (RCM) monitors the air bag indicator for open and short to ground conditions. If the ECS detects an open or short to ground condition on the air bag indicator circuit, it will store a Diagnostic Trouble Code (DTC) B1892 in memory. If the RCM detects a circuit failure on the connection to the cluster, it will store diagnostic trouble code (DTC) B1891 in memory and flash lamp on the air bag 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.
