B2294 Mercury Code - Restraint System Curtain Fault

Quick Answer

The Restraints Control Module (RCM) continuously monitors the driver and passenger safety canopy module circuits (loop) for an acceptable resistance range, unacceptable voltage and shorts to ground. Common causes include Faulty Safety Canopy Module, Safety Canopy Module harness is open or shorted, Safety Canopy Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2294 Mercury Description

The Restraints Control Module (RCM) continuously monitors the driver and passenger safety canopy module circuits (loop) for an acceptable resistance range, unacceptable voltage and shorts to ground. The RCM will set on-demand and store DTC B2294 in memory if any of these conditions are detected to be outside of their respectful range. If the RCM detects a fault, it will send a message to the instrument cluster module to illuminate the air bag warning indicator.
As the RCM continuously monitors safety canopy module circuits for resistance, it expects a normal resistance between 1.31 to 4.29 ohms.
If a loop resistance is between 0.9 and 1.31 or between 4.29 and 5 ohms, there exists a strong potential for an intermittent fault, a DTC may or may not set. The RCM will also set an on-demand DTC if the loop resistance is less than 0.9 ohm or greater than 5 ohms.

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.
