Mode 1 (PCM Adaptive Memory Drive Mode)

  1. Using scan tool, check RFCFLAG PID status. If RFCFLAG PID is on, procedure is complete, PCM has adaptive memory. If RFCFLAG PID is off, perform following procedure before performing EGR monitor repair verification drive mode or HO2S/TWC monitor repair verification drive mode.
  2. Start engine and warm to normal operating temperature. Ensure all electrical and A/C loads are off. Ensure ignition timing and idle speed are within specification. Adjust as necessary. See BASIC DIAGNOSTIC PROCEDURES article. Ensure nothing is connected to DLC. Increase engine RPM to specified speed. See Fig 1 .
  3. Operate engine at specified RPM for minimum of 15 seconds. Idle engine for more than 20 seconds when cooling fan stops. Using scan tool, monitor RPM PID, FAN2 PID (with A/C) or FAN1 PID (without A/C). Turn ignition off and on. Using scan tool, check RFCFLAG PID to confirm PCM adaptive memory status. If RFCFLAG PID is on, procedure is complete, PCM has adaptive memory. If RFCFLAG PID is off, go back to previous step.
