Can a dead battery cause body electrical codes?

Yes, low battery voltage is a very common cause of body electrical codes. When voltage drops, body control modules can store false codes. Always check battery health first before replacing components.

How much does a body control module replacement cost?

BCM replacement typically costs $300-$800 including programming. However, many body electrical codes are caused by simple wiring or fuse issues that cost much less to repair.

B0006

Passenger Frontal Airbag Deployment Loop Circuit Open

Criticalelectrical

Overview

The B0006 code indicates that the body control module has detected a passenger frontal airbag deployment loop circuit open condition. This relates to the vehicle's body electrical systems, which control comfort, convenience, and safety features. When this code is stored, the affected system or component may not operate correctly, potentially impacting safety or comfort features.

Symptoms

Turn signals flashing rapidly or not at all
Headlights or taillights not functioning
Instrument cluster warning lights erratic
Windshield wipers not operating or stuck

Common Causes

Failed window/lock/seat motor
Faulty SRS/airbag control module
Blown fuse or faulty relay
Corroded or damaged wiring harness connectors

Diagnosis Steps

1Connect an OBD-II scanner and read all stored body control module trouble codes
2Inspect the affected circuit fuse and relay; replace if blown or faulty
3Check the wiring harness and connectors for damage, corrosion, or loose pins
4Test circuit voltage and ground with a multimeter at the affected component
5Verify battery voltage is within specification (12.4V+ engine off)

Estimated Repair Cost

Frequently Asked Questions

Driving with the airbag warning light on means the SRS system may not deploy in a crash, which significantly increases injury risk. Have the system inspected as soon as possible.
