IPC Specific Override Displays: Is08

OPTION 1 override allows the ability to change vehicle option content information that is stored in IPC memory. The IPC uses this information to determine how to operate displays and other electronic devices. Incorrect option content information in IPC causes many different problems.

Upon selection of override, the option content information number will be displayed. To determine the proper OPTION 1 number, determine if vehicle is equipped with either of the following, and then add or subtract the number amount using the WARMER (increase) or COOLER (decrease) buttons.

If vehicle has French Canadian displays, add 128. If vehicle has Ride Control, add 8. If vehicle is not equipped with one or both of these options, subtract the amount from OPTION 1 number. When correct number is reached, simultaneously press and hold ECON and FRONT DEFROST buttons for 3 seconds to permanently store NEW correct value in EEPROM. Display will blank momentarily and then display new number.
