Resetting Keep-Alive Memory (KAM)

  1. Resetting KAM will return PCM memory to its default setting. If not using a scan tool, disconnect negative battery terminal for a minimum for 5 minutes then go to next step. If using New Generation Star (NGS) scan tool, turn ignition on. Select ACTIVE COMMAND MODES, then RESET KEEP ALIVE MEMORY. Go to next step.
  2. After KAM has been reset, engine must idle for 15 minutes to learn new idle air trim values. Idle quality will improve as strategy adapts. Adaptation occurs in 4 separate modes with engine idling, transmission selector and A/C in specified position. See IDLE AIR TRIM LEARNING MODES  .
