What is a Dodge Grand Caravan RT airbag control module?
The Dodge Grand Caravan RT airbag control unit is the central safety unit that activates all occupant restraint systems in the event of a crash. It monitors sensors, stores crash data, and ensures the proper function of all airbag modules and seatbelt pretensioners in the vehicle, which is critical for occupant safety.
This module, also called the Occupant Restraint Controller (ORC), controls the entire Supplemental Restraint System (SRS).
It processes signals from various crash sensors and is responsible for triggering the airbags and seat belt tensioners.
Why is the Dodge Grand Caravan RT airbag control module defective?
The Dodge Grand Caravan RT airbag control unit often fails because it permanently stores crash data after an impact, which can prevent the system from continuing to function, or internal components such as capacitors can fail. Communication errors in the CAN bus or age-related wear can also lead to failure, causing the airbag warning light to stay illuminated and requiring a Dodge Grand Caravan RT airbag control unit repair.
After an accident, the control unit often locks itself to prevent accidental activation and requires a reset.
Internal hardware defects or power fluctuations can also affect functionality, making a comprehensive diagnosis necessary.
If the airbag warning light in the Dodge Grand Caravan RT stays on, this usually indicates a fault in the airbag control unit.
Common error codes for Dodge Grand Caravan RT airbag control unit repair
During Dodge Grand Caravan RT airbag control unit repairs, specific error codes may occur that indicate communication problems or internal hardware defects within the control unit itself. These OBD-II B-codes and U-codes help the repair shop diagnose the cause directly within the airbag control unit, without affecting external sensors or components.
- B1000 → Control unit communication error → Airbag ECU (Internal defect or missing connection to the main control unit)
- U0151 → Loss of communication with Occupant Restraint Controller (ORC) → Airbag ECU (The main control unit cannot establish a connection with the airbag module)
These codes are typical of a control module failure in the Dodge Grand Caravan RT and often require repair or replacement of the module.
They differ from codes that specifically indicate sensors, seat belt pretensioners, or other external components.
