B2293 Mercury Code - Restraint System Air Bag Fault
Quick Answer
The Restraints Control Module (RCM) continuously monitors all front air bag module circuits (loop) for an acceptable resistance range, unacceptable voltage and shorts to ground. Common causes include Faulty Driver Air Bag Module, Driver Air Bag Module harness is open or shorted, Driver Air Bag 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 B2293 Mercury Description
As the RCM continuously monitors all front air bag module circuits for resistance, it expects a normal resistance for the driver and passenger air bag modules loop 1 and 2, between 1.31 to 4.29 ohms.
If a loop resistance for the driver and/or passenger air bag loop 1 and/or 2 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.
What are the Possible Causes of the DTC B2293 Mercury?
- Faulty Driver Air Bag Module
- Driver Air Bag Module harness is open or shorted
- Driver Air Bag Module circuit poor electrical connection
- Faulty Clockspring
- Faulty Restraints Control Module (RCM)

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.
