Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review GENERAL TROUBLESHOOTING INFORMATION . If the misfire is frequent enough to trigger detection of increased emissions during two consecutive driving cycles, the MIL will come on, and DTC P0300 (and some combination of P0301 through P0304) will be stored. If the misfire is frequent enough to damage the catalyst, the MIL will flash whenever the misfire occurs, and DTC P0300 (and some combination of P0301 through P0304) will be stored. When the misfire stops, the MIL will remain on. If any of the DTCs listed below are indicated at the same time as the random misfire DTCs, troubleshoot those DTCs first, then recheck for random misfire DTCs: P0101, P0102, P0103: Mass airflow (MAF) sensor P0107, P0108: Manifold absolute pressure (MAP) sensor P0171, P0172: Fuel system P0335, P0339: Crankshaft position (CKP) sensor P0365, P0369: Camshaft position (CMP) sensor P0506, P0507: Idle control system P2646, P2647, P2648, P2649: VTEC system

1. Honda diagnostic system (HDS) tablet tester
2. Honda interface module (HIM) and an iN workstation with the latest HDS software version
3. HDS pocket tester
4. GNA600 and an iN workstation with the latest HDS software version

Any one of the above updating tools can be used.

Note. Use this procedure when you need to update the ECM/PCM at any time. Make sure the HDS/iN workstation has the latest HDS software version. Before you update the ECM/PCM, make sure the battery in the vehicle is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. Never turn the ignition switch to ACC (I) or LOCK (0) during the update. If there is a problem with the update, leave the ignition switch ON (II). To prevent ECM/PCM damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, door locks, etc.) during the update. To ensure the latest program is installed, do an ECM/PCM update whenever the ECM/PCM is substituted or replaced. You cannot update an ECM/PCM with a program it already has. It will only accept a new program. High temperature in the engine compartment might cause the ECM/PCM to become too hot to run the update. If the engine has been running before this procedure, open the hood and cool the engine compartment. If you need to diagnose the Honda interface module (HIM) because the HIM's red (# 3) light came on or was flashing during the update, leave the ignition switch in ON (II) when you disconnect the HIM from the data link connector (DLC). This prevents damage to the ECM/PCM.

Scheme 185

1. Turn the ignition switch to ON (II), but do not start the engine.
2. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
3. Make sure the HDS communicates with the ECM/PCM and other vehicle systems. If it doesn't, go to «DLC CIRCUIT TROUBLESHOOTING»(ref-320426-S32678800202009071400000) . If you are returning from the DLC circuit troubleshooting, skip steps 4 and 5 , and clean the throttle body after updating the ECM/PCM (see «THROTTLE BODY CLEANING»(ref-320437-S26671565662009071400000) ).
4. Select the INSPECTION MENU with the HDS.
5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure.
6. Exit the HDS diagnostic system, then select the update mode, and follow the screen prompts to update the ECM/PCM.
7. If the software in the ECM/PCM is the latest, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the ECM/PCM is not the latest, follow the instructions on the screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the ECM/PCM update system requires you to cool the ECM/PCM, follow the instructions on screen. If you have a problem during the update procedure (programming takes over 15 minutes, status bar goes over 100%, D (A/T) or immobilizer indicator flashes, HDS tablet freezes, etc.), follow these steps to minimize the chance of damaging the ECM/PCM: Leave the ignition switch in the ON (II) position. Connect a jumper battery (do not connect a battery charger). Shut down the HDS. Disconnect the HDS from the DLC. Reboot the HDS. Reconnect the HDS to the DLC, and try the update procedure again.
8. If the TP POSITION CHECK failed in step 5 , clean the throttle body (see «THROTTLE BODY CLEANING»(ref-320437-S26671565662009071400000) ).
9. Do «ECM/PCM IDLE LEARN PROCEDURE»(ref-320447-S03803966382009071400000) .
10. Do the CKP pattern learn procedure (see «CKP PATTERN CLEAR/CKP PATTERN LEARN»(ref-320425-S23638437822009071400000) ).

1. Honda diagnostic system (HDS) tablet tester
2. Honda interface module (HIM) and an iN workstation with the latest HDS software version
3. HDS pocket tester
4. GNA600 and an iN workstation with the latest HDS software version

Any one of the above updating tools can be used.

Note. Make sure the HDS/iN workstation has the latest HDS software version.
