Reprogram PCM EEPROM Option To Enable Cruise Bit
IMPORTANT:
In order to set the CRUISE CONTROL option to YES, the entire PCM has to be reprogrammed. The latest software and calibrations can be selected for downloading if this is desired.
Change the CRUISE CONTROL option to YES by reprogramming the powertrain control module (PCM) using the Service Stall System (SSS). Refer to the Service Stall System (SSS) User Guide for reprogramming procedures.
