Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Car Configuration Parameters
Car configuration parameters affect both the BCM and IPC . The parameters are set in the BCM . The parameters are also set in the IPC as backup data for service, in case online As-Built data is not available.
A scan tool is required to set the car configuration parameters. During a Programmable Module Installation (PMI) of the BCM , As-Built data must be obtained and installed. Any changed customer preference items are returned to the factory settings and must be manually reset.
