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.
Customer Driven Preferences
Second type of configuration data is customer preference driven. These are items that the customer may or may not want to have enabled. Typically, customer preference items can be toggled on or off with compatible scan tool. You may need to ask the customer which preferences they had enabled prior to installation of new module. To carry out customer configuration process, use PDU. On PDU select CUSTOMER PREFERENCE INDEX for modules on the vehicle that have customer preference items. Configure items as necessary. See CUSTOMER PREFERENCE INDEX table.
| Customer Preference | Index Module | Configurable Item State |
|---|---|---|
| GEM, DDM | Smart Locks | ON/OFF |
| GEM, DDM | Automatic Locks | ON/OFF |
| GEM | Illuminated Exit | ON/OFF |
| DDM | Horn Chirp | ON/OFF |
