Campaign - EV-ECU Software Update For Charger Usage: Overview
No: SC-13-001DATE: January, 2013
MODEL: 2012 i-MiEV
PURPOSE
The current internal software programming for the EV-ECU is incompatible with the Electric Vehicle Supply Equipment charger produced by Clipper Creek. Use of a Clipper Creek charger could potentially damage the internal components within the i-MiEV electrical system. If this damage occurs it could potentially affect the i-MiEVs ability to start. This bulletin describes the procedures necessary to update the software programming of the EV-ECU to ensure compatibility between an i-MiEV and the Clipper Creek EVSE.
AFFECTED VEHICLES
2012 i-MiEV built from 10/28/2011 - 9/07/2012
CUSTOMER NOTIFICATIONS
A letter will be sent to all owners of affected vehicles requesting them to bring their vehicle to a local certified Mitsubishi i-MiEV dealer to have their EV-ECU updated to the latest software. A copy of the customer notification letter appears at the end of this bulletin.
REQUIRED OPERATIONS
Before starting this campaign procedure CHECK THE WARRANTY SUPERSCREEN to verify if the vehicle is an affected VIN for this campaign and this campaign procedure has not already been completed.
Repairs must be completed by a certified i-MiEV technician. Please ensure the Main Drive battery's charge is properly maintained while the vehicle is not being serviced.
SPECIAL EQUIPMENT
The following equipment is needed to reprogram the EV-ECU:
^ VCI (Vehicle Communication Interface) - MB991824.
^ MEDIC Laptop computer with A/C power adapter - 520924 or 547708.
^ MUT-III main harness 'A' (blue connector at the DLC end) - MB991910.
^ USB 2.0 cable - MB991827.
^ Reprogramming Database N12121 or higher
^ MEDIC 3 update at 163 or higher.
^ Standalone MUT-III laptop with Reprogramming CD 01/13 installed.
REPAIR PROCEDURE
1. Verify the MEDIC 3 is at update 163 or higher.
If your MEDIC 3 update is at least 163 continue with the REPROGRAMMING PROCEDURE below.
If your MEDIC 3 update is below 163, update your MEDIC 3 as follows.
2. Select the MEDIC 3 "Admin" tab. Click on "Updates."
For MEDIC 3 users only: (Stand alone MUT-III users go to step 5)
3. If the MEDIC Updates screen advises updates are available, click the "Begin" button.
4. Once MEDIC 3 is at update 163 or higher, continue to the REPROGRAMMING PROCEDURE.
5. Standalone MUT-III Scan Tool Viewer (SVT) ONLY: (MEDIC 3 USERS go to the REPROGRAMMING PROCEDURE below).
Verify that your MUT-III has the most current version of the reprogramming database:
a. From the MUT-III Main Page:
^ Select "Special Function"
^ Select "ECU Reprogramming"
^ Select "Database File Display-CAN"
^ Confirm the database number displayed at the top right of the chart is N12121.
1. If the database number displayed on your MUT-III is N12121 or greater, continue to the Reprogramming Procedure below.
2. If the database number displayed on your MUT-III is lower than N12121, locate the Yellow MUT-Ill Reflash CD 01/13 and follow the instructions on the CD label to update your MUT-III.
REPROGRAMMING PROCEDURE
1. With the vehicle parked set the parking brake and open the hood.
2. Remove the 12V auxiliary battery cover. Unscrew the plastic nut (pull up while turning).
3. Attach the battery charger (with a charging rate not to exceed 10 amps) to the 12V auxiliary battery.
NOTE:
Ensure battery charger does not time out during this procedure.
NOTE:
Connect the positive (+) terminal of the 12V auxiliary battery (1) to the positive (+) battery charger cable (2). Connect the negative (-) battery charger cable (3) to the designated ground location (4).
4. Connect MUT-III as follows:
^ Turn the laptop computer on. If you're running on battery power and the charge indicator in the lower right hand corner of the screen does not show a full charge, it is recommended that either the laptop battery be charged prior to beginning, or that reprogramming be completed with the A/C power adaptor connected to the laptop.
^ Connect the USB cable to the VCI.
^ When the laptop displays the MUT-III main screen, connect the USB cable to the laptop.
^ Connect the MUT-III main harness with the blue DLC connection to the VCI.
^ Connect the blue connector of the MUT-III main harness to the vehicle's data link connector.
^ Turn the VCI power switch ON. Verify that the indicator lamp in the upper right corner of the screen is green.
5. Turn the electric motor switch to the ON position.
NOTE:
Ensure all accessories are off (e.g. lights, heating and AC system, audio/navi unit, etc...).
