The B00A0 diagnostic trouble code (DTC) pertains to the Occupant Classification System Module (OCSM), commonly known as the passenger weight sensor located under the passenger seat. This sensor determines the presence and weight of the passenger to control airbag deployment appropriately.
If B00A0 is the Only Code Present:
When B00A0 is the sole code detected, it typically indicates that the occupant weight sensor requires calibration. This calibration can be performed using a diagnostic scan tool. The general steps are as follows:
-
Connect the Scan Tool: Attach the diagnostic scan tool to the vehicle's data link connector, usually located under the driver's side dashboard.
-
Access the SRS Airbag Menu: Navigate to the Supplemental Restraint System (SRS) or Airbag section within the scan tool's interface.
-
Select Occupant Classification System: Choose the option related to the Occupant Classification System, which may be labeled as "Occupant," "OPDS," or "Weight Sensor."
-
Perform Calibration: Initiate the calibration process, often referred to as "Zero out weight," "Initialize," or "Calibrate." Follow the on-screen prompts to complete the procedure.
-
Clear Codes: After successful calibration, clear any existing codes to reset the system.
It's important to note that specific steps may vary depending on the vehicle make and model, as well as the scan tool used. For detailed instructions tailored to your vehicle, you can refer to MyAirbags' guide on calibrating the occupant weight sensor. Please click here: MyAirbags
If B00A0 and a Crash Code are Present:
If both B00A0 and a crash-related code are present, it indicates that the airbag control module has stored crash data. In such cases, the airbag control module requires a reset to clear the crash data and restore proper functionality. This reset process involves reprogramming the module to its original factory settings.
MyAirbags offers reset services for airbag control modules, ensuring that all crash data and fault codes are cleared. Their process includes:
-
Module Reset: Erasing all crash data and hard codes stored in the airbag control module.
-
Quality Assurance: Validating each unit to ensure there are no electronic issues.
-
