Special Tools Required
11-227
ECM/PCM Update
A
 Honda diagnostic system (HDS) tablet tester
 Honda interface module (HIM) and an iN workstation
with the latest HDS software version
 HDS pocket tester
 GNA 600 and 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.
 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 LOCK (0) or ACC (I) during the update. If there is a problem with the
update, l eave the ignition switch to ON (II).
 To prevent ECM/PCM damage, do not operate anything electrical (headlights, audio system, brakes,
A/C, power windows, moonroof (if equipped), door
locks, etc.) during the update.
 To ensure the latest program is installed, do an ECM/ PCM update when ever 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 was 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, l eave the ignition
switch in ON (II) when you disconnect the HIM from
the data link connector (DLC). This will pr event ECM/
PCM damage. 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. If it doesn’t, go to the DLC circuit
troubleshooting (see page 11-204). If you are
returning from the DLC circuit troubleshooting, skip
steps 4 to 5 and clean the throttle body after
updating the ECM/PCM (see page 11- 344).
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 (A/T),
make sure you update both.
NOTE: If the ECM/PCM update system requires you
to cool the ECM/PCM, follow the instructions on the
screen. If you have a problem during the update
(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 ON (II).
 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 do the update again.
8. If the TP POSITION CHECK failed in step 5, clean the throttle body (see page 11- 344).
9. Do the ECM/PCM idle learn procedure (see page 11-310).
10. Do the CKP pattern clear/CKP pattern learn procedure (see page 11-4).  Honda diagnostic system (HDS) tablet tester

3. Make sure the HDS communicates with the ECM/ PCM and other vehicle systems. If it doesn’t, go to
the DLC circuit troubleshooting (see page 11-204). If
you are returning from DLC circuit troubleshooting,
skip steps 4 through 9, 20 through 25, and 28
through 30, and do these procedures after
replacing the ECM/PCM;
 Replace the engine oil (see page 8-10) and the engine oil filter (see page 8-11).

8. A/T model: Select the A/T system with the HDS.
9. A/T model: Select the REPLACE TCM/PCM MENU, then select READ DATA and follow the screen
prompts.
NOTE: Doing this step copies (READS) the ATF life data from the original PCM so you can later download
(WRITES) it into the new PCM.
 If READ DATA indicates FAILED, continue with this procedure. 10. Turn the ignition switch to LOCK (0).
11. Jump the SCS line with the HDS.
12. Do the battery removal procedure (see page 22-69).
13. Remove the cover (A).
14. Remove the bolts (D), then remove the ECM/PCM
