  • Hello, I've reviewed the diagnostic guide for the 2005 Chrysler 300 Limited. This document focuses on troubleshooting the B2206 error, involving VIN mismatch issues, the OCM, ORC, and PCM modules, as well as seat weight sensor verification. I am ready to answer your questions about the troubleshooting steps and related procedures outlined in this guide.
  • What does the B2206 error code indicate?
    What should I do if the VIN stored in the PCM does not match the vehicle's VIN?
    What components are checked in this diagnosis?
