Mode 1 - PCM Adaptive Memory Produce Drive Mode

1. Start engine and let it idle until reaches normal operating temperature.
2. Verify if vehicle is under following conditions, perform correction if necessary:
   • All accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
   • Initial ignition timing and idle speed are within specification. For adjustments see IDLE SPEED & IGNITION TIMING in ON-VEHICLE ADJUSTMENTS article.
   • TEN and GND terminals of DLC-1 are not connected.
3. Race engine speed as shown in graph. See Fig 1. Then idle engine for more than 20 seconds, after cooling fan has stopped. If possible, monitor RPM PID for engine speed and FAN1 PID (without A/C) or FAN2 PID (with A/C) for cooling fan status during this procedure.
