Code B1419 Mercury Description

The Restraint Control Module (RCM) monitors the driver front door and RH C-pillar side impact sensors and circuits for the following faults: Open circuit, Short to voltage, Short to ground, Faulted driver front door side impact sensor, Faulted RH C-pillar side impact sensor. If a fault is detected, the RCM stores DTC B1419 in memory and sends a message to the Instrument Panel Cluster (IPC) to illuminate the airbag warning indicator. The RCM communicates with each impact sensor. If the RCM is unable to communicate with the sensor, a Diagnostic Trouble Code (DTC) is stored in memory. A Continuous Memory Diagnostic Trouble Code (CMDTC) no operation can be set by a short to voltage on the return circuit of the impact sensor.

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.
