This bulletin supercedes TSB-19-54-001REV, issued March, 2019, to correct Warranty Coverage in
Warranty Information. Revisions are italicized and indicated by A.

PURPOSE
During quick charging of the traction battery using the ABB quick charger, an isolation error may
be detected by the charger, causing charging to stop approximately 2 minutes after charging was
started.
This TSB instructs dealers to reprogram the BMU (i-MiEV) or sub-BMU (Outlander PHEV) with
updated software to correct the issue.

BACKGROUND
When the BMU or sub-BMU is in operation, the coupling condenser provided in the current leak
detection circuit repeats charging and discharging and its duration is monitored by the sub-BMU
to judge if current leak occurs in the high voltage circuit.
On the other hand, during the quick charging process the sub-BMU does not carry out current leak
judgement as it is done by the charger side. But as charging and discharging of the coupling
condenser continues even during quick charging, it is possible that the charger misjudges a current
leak due to voltage fluctuation in the high voltage circuit.

AFFECTED VEHICLES
D

2016 - 2017 i-MiEV vehicles, and for BMU service parts produced before mid-March, 2019.

D

2018 - 2019 Outlander PHEV vehicles, produced before the following VINs:
D

U.S. And Puerto Rico: JA4J24A50KZ036473 (January 10, 2019)

D

Canada: JA4J24A55KZ607102 (January 10, 2019)

REQUIRED OPERATIONS
1.
2.

Confirm your MUT-III is updated with the latest reprogramming database.
Reprogram the BMU or sub-BMU with the new software. Refer to the “BMU/Sub-BMU
Reprogramming Chart” for new software information.

IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before
reprogramming, and DTCs are listed in the BMU or Sub-BMU memory, diagnose and repair those
DTCs per the service manual before reprogramming. DO NOT reprogram the BMU or Sub-BMU until
the reason(s) for other DTCs being set is corrected.

REPAIR PROCEDURE
SOFTWARE/MEDIC VERSION VERIFICATION
1.

Verify that the BMU/Sub-BMU has not already been updated to the latest S/W number in the
table above.
If the BMU/Sub-BMU is at the latest level, reprogramming is not necessary.

NOTE: Reprogramming the BMU/Sub-BMU with the latest database (e.g., N190301 ) includes all past and
current reprogramming for TSBs of affected vehicles. It is not necessary to reprogram the
BMU/Sub-BMU for each previous TSB.

For MEDIC 3.5/4 users only: (MUT-III STV users go to
step 5)
2.

Verify the MEDIC 3.5/4 is at version 3.5 and at
update 586 or higher.
If your MEDIC 3.5/4 update is at least 586, continue
with the Reprogramming Procedure.

STANDALONE MUT-III SCAN TOOL VIEWER (STV)
ONLY:
(MEDIC 3.5 USERS - GO TO THE
REPROGRAMMING PROCEDURE). Verify that your
MUT3-SE has the most current version of the
reprogramming database:
From the MUT3-SE Main Page:
a.

Click “STV.”

b. Click the “ECU Reprogramming” button.

c.

Click “SDB Data List.”

d. Confirm that the database number displayed in
the upper right above the chart is N190301 or
higher.

If the database number displayed on your
MUT3-SE is N190301 or higher, continue to
the next section.

D

If the reprogramming database number
displayed on your MUT3-SE is lower than
N190301, then the MUT3-SE database
needs to be updated.

Once database number is confirmed, hit the
Home button to go back to the System Select
screen.
