IMA Motor/IMA Battery Update

The MCM contains the software programs for the IMA motor control and the battery module condition monitor.

NOTE:

- Make sure the HDS/iN workstation or the MVCI has the latest HDS software version.
- To ensure the latest programs are installed, do an MCM update whenever the MCM is substituted or replaced.
- If you are using the HIM, select the IMA motor and/or the battery module in the HIM MCM update menu.
- You can not update an MCM with the program it already has. It will only accept a new program.
- Before you update the MCM, make sure the vehicle's 12 V battery is fully charged.
- Never turn the ignition switch to ACCESSORY (I) or LOCK (0) during the update. If there is a problem with the update, leave the ignition switch turned ON (II).
- To prevent MCM 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 ON (II) when you disconnect the HIM from the data link connector (DLC). This prevents damage to the MCM.

1. Turn the ignition switch to ON (II). Do not start the engine.

2. Connect the updating tool to the data link connector (DLC) (A) located under the driver's side of the dashboard.





3. Make sure the updating tool communicates with the vehicle and the MCM. If it doesn't, troubleshoot the DLC circuit DLC Circuit Troubleshooting (IMA System).

4. If the software is the MCM is not the latest, do the MCM update procedure as described on the HIM label and in the MCM update system.
