HOW TO TROUBLESHOOT CIRCUITS AT THE ECM/PCM CONNECTORS

Special Tools Required



Digital multimeter KS-AHM-32-003 (1) or a commercially available digital multimeter



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.

UPDATING THE ECM/PCM

Special Tools Required



Honda diagnostic system (HDS) tablet tester



Honda interface module (HIM) and an iN workstation with HDS and CM update software



HDS pocket tester



GNA 600 and an iN workstation with HDS and CM update software

1. Turn the ignition switch ON (II), but do not start the engine.

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.

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 the

DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ). 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 ).

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.

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 TP POSITION CHECK indicates FAILED, continue this procedure.

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.

8. If the TP POSITION CHECK failed in step 5, clean the throttle body (see THROTTLE BODY

CLEANING ).

9. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

10. Do the crank (CKP) pattern learn procedure.

SUBSTITUTING THE ECM/PCM

Special Tools Required



Honda diagnostic system (HDS) tablet tester



Honda interface module (HIM) and an iN workstation with HDS and CM update software



HDS pocket tester



GNA 600 and an iN workstation with HDS and CM update software

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 ON (II).

3. Make sure the HDS communicates with the ECM/PCM. If it doesn't, go to the DLC circuit

troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ). 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 ).

4. Select the INSPECTION MENU with the HDS.



Reboot the HDS.



Reconnect the HDS to the DLC, and try the update procedure again.

NOTE:

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