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.
Programmable Module Installation (PMI)
The PMI method is used when a new, programmable module is installed in the vehicle. It is no longer necessary to command the diagnostic tool to gather module option content from the old module. The diagnostic tool (WDS only) automatically obtains any available module option content information from the old module during the vehicle ID routine that runs when the diagnostic tool is initially connected to the vehicle. It is important to connect the WDS to the vehicle and allow it to identify the vehicle and obtain configuration data prior to removing any modules.
