Special Tools Required

  1. Digital multimeter KS-AHM-32-003 (1) or a commercially available digital multimeter
  2. Backprobe set 07SAZ-001000A (2)

  1. Connect the backprobe adapters (A) to the stacking patch cords (B), and connect the cords to a digital multimeter (C).
  2. Using the wire insulation as a guide for the contoured tip of the backprobe adapter, gently slide the tip into the connector from the wire side until it touches the end of the wire terminal.
  3. If you cannot get to the wire side of the connector or the wire side is sealed (A), disconnect the connector and probe the terminals (B) from the terminal side. Do not force the probe into the connector. NOTE: Do not puncture the insulation on a wire. Punctures can cause poor or intermittent electrical connections.
  1. Honda diagnostic system (HDS) tablet tester
  2. Honda interface module (HIM) and an iN workstation with HDS and CM update software
  3. HDS pocket tester
  4. GNA600 and an iN workstation with HDS and CM update software

Note. Use this procedure when you need to update the ECM/PCM during troubleshooting procedures. Make sure the HDS/HIM has the latest software version down loaded from the iN (interactive network). 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 OFF during the update. If there is a problem with the update, leave the ignition switch ON. 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. If you need to diagnose the Honda interface module (HIM) because the HIM's red (# 3) light came on or was flashed during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent ECM/PCM damage.

  1. Turn the ignition switch 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 system. If it doesn't, go to «DLC CIRCUIT TROUBLESHOOTING»(ref-355245-S06359967292010012100000) . If you are returning from the DLC circuit troubleshooting, skip step 4 and 5 , then clean the throttle body after updating the ECM/PCM (see «THROTTLE BODY CLEANING»(ref-290823-S19534659422008072200000) ).
  4. Select the INSPECTION MENU with the HDS.
  5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the screen prompts with the HDS. 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 run into a problem (programming takes over 15 minutes, status bar goes over 100%, D or immobilizer indicator flashes, HDS tablet freezes, etc.) during the update procedure, 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-290823-S19534659422008072200000) ).
  9. Do «ECM/PCM IDLE LEARN PROCEDURE»(ref-290807-S02808252682008072200000) .
  10. Do the crank (CKP) pattern learn procedure.
  1. Honda diagnostic system (HDS) tablet tester
  2. Honda interface module (HIM) and an iN workstation with HDS and CM update software
  3. HDS pocket tester
  4. GNA 600 and an iN workstation with HDS and CM update software

Any one of the above updating tools can be used.

Note. Use this procedure when you need to substitute a known-good ECM/PCM during troubleshooting procedures.

  1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
  2. Turn the ignition switch to ON (II).
  3. Make sure the HDS communicates with the ECM/PCM. If it doesn't, go to «DLC CIRCUIT TROUBLESHOOTING»(ref-355245-S06359967292010012100000) . If you are returning from DLC circuit troubleshooting, skip steps 4 thru 14 , then clean the throttle body after substituting the ECM/PCM (see «THROTTLE BODY CLEANING»(ref-290823-S19534659422008072200000) ).
  4. Select the INSPECTION MENU with the HDS.
  5. Select the ETCS TEST, then select the TP POSITION CHECK and follow the screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure.
  6. Turn the ignition switch to LOCK (0).
  7. Jump the SCS line with the HDS.
  8. Remove the passenger's dashboard undercover (see «PASSENGER'S DASHBOARD UNDERCOVER REMOVAL/INSTALLATION»(ref-290806-S30518185312008072200000) ), the passenger's kick panel (see «TRIM REMOVAL/INSTALLATION - DOOR AREAS»(ref-290846-S09306060772008072200000) ), and the glove box (see «GLOVE BOX REMOVAL/INSTALLATION»(ref-290806-S13331020522008072200000) ).
  9. Cut the plastic cross brace in the glove box opening with diagonal cutters in the area shown, and discard it.

  16. Open the SCS line with the HDS.
  17. Turn the ignition switch to ON (II). NOTE: DTC P0630 "VIN Not Programmed or Mismatch" may be stored because the VIN has not been programmed into the ECM/PCM; ignore it, and continue this procedure.
  18. Manually input the VIN to the ECM/PCM with the HDS.
  19. Select the IMMOBI SYSTEM with the HDS.
