BCM Override Parameters:: BS06

Option Content No. 1 - This override allows the ability to change contents of which options the vehicle's BCM has stored in its EEPROM. This option content is displayed in trip odometer as a number from 0 to 255. Each number is a code which represents option content. BCM uses this value to determine how to operate the displays and electronic controls. Incorrect option values cause many different problems. To determine proper option value, add up following options that vehicle is equipped with:

Take total of actual options vehicles has from above list and compare it with Option 1 value on ECCP display. If the two are different, correct Option 1 value using following procedure. To change option content number press TEMP UP or TEMP DOWN button for override control until desired number appears, (corresponding to total of actual options vehicle does have). Next, press and hold HEATER and DEFROST buttons simultaneously for 3 seconds. This will reprogram BCM EEPROM to number of options displayed on the IPC odometer.
