How to Update the ECM/PCM
2006 Honda Element EX, 2.4 YH1, StandardSECTION How to Update the ECM/PCM
NOTE:
- 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 the program it already has. It will only accept a new program.
- Before you update the ECM/PCM, make sure the vehicle's battery is fully charged.
- To prevent ECM/PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, door locks, etc.) during the update.
- 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 the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent ECM/PCM damage.
- Turn the ignition switch ON (II). Do not start the engine.
- Connect the HDS or the Honda interface module (HIM) to the data link connector (DLC) (A) located under the driver's side of the dashboard.
- If the HDS does not have the update function, disconnect the HDS from the vehicle and connect the Honda interface module (HIM).
- If the software in the ECM/PCM is the latest, disconnect the HDS or the 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, do the ECM/PCM update procedure as described on the HIM label or in the ECM/PCM update system.
- Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).
- Do the CKP pattern clear/pattern learn procedure.
