Drive Motor Control Module: Testing and Inspection

MCM (Motor Control Module) Update

Special Tools Required

- Honda diagnostic system (HDS) tablet tester
- Honda interface module (HIM) and an iN workstation with the latest HDS software version HDS pocket tester
- GNA600 and an iN workstation with the latest HDS software version
Any one of the above updating tools can be used.

Use this procedure when you need to update the MCM during a troubleshooting procedure.

The MCM has the programs for the IMA motor control.

Update the MCM if its program is not the latest.

NOTE:

- Make sure the HDS/iN workstation has the latest HDS software version.

- To ensure the latest programs are installed, do an MCM update whenever the MCM is substituted or replaced.

- Select IMA motor and/or IMA battery in the HIM MCM update menu.

- You can not update a 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.

- Do not turn the ignition switch to ACC (I) or to LOCK (0) while updating the MCM. If you do, the MCM can be damaged.

- 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 will prevent MCM damage.

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

2. Connect the HDS or the Honda Interface Module (HIM) to the data link connector (DLC) (A) located under the driver's side of dashboard.

3. Make sure the HDS communicates with the vehicle, the BCM module, and the MCM If it doesn't, troubleshooting the DLC circuit.. Testing and Inspection

4. Do the MCM update procedure as described on the HIM label and in the CM update system.
