INTRODUCTION

Starting with the launch of the i-HDS software, updating (rewriting) a vehicle control module will require a dedicated i-HDS laptop and an approved vehicle communications interface (VCI).

NOTE: The CM Update (rewrite) feature within the MVCI menu is removed and is no longer supported.

The procedures in this service bulletin are used and referenced in other service bulletins.

For detailed information on i-HDS usage, refer to the i-HDS Quick Start Guide on SIS. Click on General Publications > Tool Information.  Most 2002 and later Honda vehicles have reprogrammable control modules. To update (rewrite) any of these control modules, you need the vehicle along with the Denso DST-i or the Bosch MVCI, and a laptop installed with the i-HDS software.  The i-HDS software includes the J2534 Rewrite icon, which is used for vehicle control module updates.

This service bulletin describes these subjects:

  • REQUIRED TOOLS AND EQUIPMENT

UPDATING TIPS AND PRECAUTIONS

  • When updating a control module/unit on a new vehicle, make sure all its fuses were installed at PDI.
  • To prevent control unit/module damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moonroof, etc.) during the update.
  • The corresponding service bulletin will always indicate the correct database update to use. To check the database update version on the i-HDS laptop, click on the HDS Download Manager icon on the taskbar

  • Do not connect an additional power supply to the DST-i or MVCI when it is connected to the vehicle; power is supplied through the DLC.
  • To ensure that the control module/unit is not permanently damaged during updating, verify that the vehicle’s 12-volt battery is fully charged before starting an update.

NOTE: If the vehicle’s 12-volt battery drops below 10 volts during the update, the programming status bar may go past 100 percent, or the updating tool may display an error message.

If a problem occurs during an update, do the following to minimize the chances of damaging the control  unit/module:

IMPORTANT: Keep the ignition ON.

  • Connect a jumper battery (do not connect a battery charger).
  • Disconnect the DST-i or MVCI from the vehicle’s DLC.
  • Restart the Rewrite application.
  • Reconnect the DST-i or the MVCI to the vehicle’s DLC, and retry the update procedure.

NOTE: Unnecessary or incorrect repairs resulting from an update (rewrite) will not be covered under warranty.
