Honda Accord: ECM/PCM Idle Learn Procedure

Do the idle learn procedure whenever you do any of these actions:
- Replace ECM/PCM.
- Reset ECM/PCM
- Update ECM/PCM.
- Replace or clean the throttle body.
- Disassemble the engine or the transmission.
NOTE: Erasing DTCs with the HDS does not require you to do the idle learn procedure.

1. Make sure all electrical items (A/C, audio, lights, etc.) are off.
2. Reset the ECM/PCM with the HDS.
3. Turn the ignition switch to ON (II), and wait 2 seconds.
4. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194 Р’В°F (90 Р’В°C).
