B2292 Mercury Code - Restraint System Seatbelt Pretensioner Fault
Quick Answer
The Restraints Control Module (RCM) continuously monitors the safety belt retractor pretensioner circuits for an acceptable resistance range, unacceptable voltage and shorts to ground. Common causes include Faulty Safety Belt Retractor Pretensioner, Safety Belt Retractor Pretensioner harness is open or shorted, Safety Belt Retractor Pretensioner 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 B2292 Mercury Description
As the RCM continuously monitors safety belt retractor pretensioner circuits for resistance, it expects a normal resistance between 1.31 and 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.
What are the Possible Causes of the DTC B2292 Mercury?
- Faulty Safety Belt Retractor Pretensioner
- Safety Belt Retractor Pretensioner harness is open or shorted
- Safety Belt Retractor Pretensioner circuit poor electrical connection
- 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.
