Mode 1 (Pcm Adaptive Memory Production Drive Mode)

1. Start the engine and warm it up completely.
2. Verify the following conditions and correct if necessary:
   • All accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
   • Initial ignition timing and idle speed are within the specification.
   • TEN and GND of DLC are not connected.
3. Perform no load racing at the engine speed shown in the graph, then idle the engine for more than 20 s  after the cooling fan has stopped. If possible, monitor RPM PID for engine speed and FAN2 PID (with A/C), FAN1 PID (without A/C) for cooling fan status during this procedure.
