B0011 Mercury Code - Passenger Frontal Stage 2 Deployment Control

Quick Answer

The Restraints Control Module (RCM) monitors all deployable device and sensor circuits for a signal cross coupled (short) between circuits. Common causes include Faulty Passenger Airbag, Passenger Airbag harness is open or shorted, Passenger Airbag 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 B0011 Mercury Description

The Restraints Control Module (RCM) monitors all deployable device and sensor circuits for a signal cross coupled (short) between circuits. If the RCM detects a short between the circuits of one device and another device, it will store a DTC for each of the signal cross coupled faults in memory. The RCM sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator. When a normal loop fault is present (one loop is either shorted to battery/ground, open circuit or low resistance), then signal cross coupled diagnostics will not be active. Once the normal loop fault is repaired, then the signal cross coupled diagnostics will resume.

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.

Frequently Asked Questions about B0011 Mercury Code

1. What are the common symptoms of OBDII code B0011 in a Mercury related to Passenger Frontal Stage 2 Deployment Control?

The common symptoms include the airbag warning light illuminating on the dashboard and the possibility of the passenger front airbag not deploying in a collision.

2. What are the possible causes of OBDII code B0011 in a Mercury?

Potential causes of this code may include a faulty passenger frontal stage 2 deployment control module, damaged wiring or connectors in the airbag system, or a malfunction in the passenger airbag itself.

3. How can I diagnose the issue related to OBDII code B0011 in my Mercury?

Diagnosing this code typically involves using a scan tool to retrieve the specific fault code, then conducting a visual inspection of the airbag system components, checking the wiring and connectors for damage, and testing the passenger frontal stage 2 deployment control module.

4. Is it safe to drive my Mercury with OBDII code B0011 present?

It is not recommended to drive the vehicle with this code active, as it indicates a potential issue with the passenger airbag system, which may compromise occupant safety in the event of a collision.

5. Can I reset the OBDII code B0011 in my Mercury without fixing the underlying issue?

While you can clear the code temporarily using a scan tool, it will likely reappear until the root cause of the problem is addressed and resolved.

6. How much does it typically cost to repair OBDII code B0011 in a Mercury?

The cost of repairing this code can vary depending on the exact cause of the issue, but it may involve replacing the passenger frontal stage 2 deployment control module, repairing damaged wiring or connectors, or addressing any other faulty components in the airbag system.

7. Are there any safety precautions I should take when working on the airbag system related to OBDII code B0011 in my Mercury?
