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.
