What is a Dodge Durango HB airbag control module?
The Dodge Durango HB airbag control unit is the central safety unit that precisely controls all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors vehicle sensors, stores relevant crash data, and is essential for the proper functioning of the entire safety system.
This component, also known as the Supplemental Restraint System (SRS) Control Module or Occupant Restraint Controller (ORC), is the brain of your Dodge Durango's passive safety system.
It receives signals from impact sensors and decides in milliseconds whether to optimally deploy the airbags to provide maximum protection for the occupants.
Why is the Dodge Durango HB airbag control unit defective?
The Dodge Durango HB airbag control module often fails because it irretrievably stores crash data after an accident or develops internal errors. When the module detects an impact, it locks itself to prevent misfires, making a reset or replacement essential.
Common causes are internal processor or memory damage, which manifests itself in permanent error codes and requires repair.
Moisture ingress or age-related material fatigue can also lead to failure of the sensitive electronics and make diagnosis more difficult.
A faulty control unit causes the airbag warning light to be permanently active and the system to no longer function.
Common error codes for Dodge Durango HB airbag control unit repair
During Dodge Durango HB airbag control unit repairs, specific error codes often occur, signaling internal problems with the module or crash data storage. These B-codes typically indicate malfunctions within the control unit itself and require professional diagnosis and repair.
- B1000: Control unit communication error – Cause: Problems in the data transmission of the airbag module.
- B1001: Airbag control unit internal memory error – Cause: Damage to the internal memory, often after an accident.
- B1002: Airbag control module self-test failed – Cause: The module could not successfully complete its functional test at startup.
- B1010: Airbag control unit protected memory error – Cause: Error in the write-protected area of the memory.
- B1013: Internal Processor Error – Cause: Malfunction of the control unit’s main processing unit.
- B1016: Voltage sensor error in the control unit – Cause: Irregularities in the internal voltage supply of the module.
- B1021: Communication error between airbag control unit and ECU – Cause: Malfunction of the internal communication in the airbag system.
- B1023: Airbag Deployment Circuit Fault – Cause: Problem in the airbag activation circuit.
- B1040: Crash Sensor Communication Error – Cause: Loss of connection to an impact sensor.
- B1046: Airbag control unit error - EEPROM damaged - Cause: Damage to the non-volatile memory after a crash.
