Resetting Keep Alive RAM will return PCM memory to its default setting. Adaptive learning contents such as idle and fuel trim are included. A PCM Reset is also part of a KAM Reset.
After Keep Alive RAM has been reset, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.
A Keep Alive Random Access Memory Reset is done as follows:
During Key ON, Engine OFF with the scan tool, use the Reset Keep Alive Memory function. This is found in the Active Command Modes menu on the New Generation Star scan tool.
If a generic scan tool is used, this function may not be supported. Refer to scan tool manufacturer's instruction manual.
If an error message is received or the scan tool does not support this function, disconnecting the battery ground cable for a minimum of 5 minutes may be used as an alternative procedure.
