RE:
Outlander PHEV sub-BMU Service Campaign
ATIN NO.
ATIN-18-SC-001-A
AFFECTED VEHICLES: Certain 2018 Outlander PHEV vehicles
PURPOSE
A service campaign will be released today for the sub-BMU reprogramming on certain 2018
Outlander PHEV vehicles built between September 14, 2017 and August 7, 2018. To maximize
customer satisfaction with the quality of their new vehicle, we recommend this service
campaign be completed prior to vehicle delivery to the customer. If this is not possible, the
vehicle can still be delivered, but please ask the customer to bring the vehicle back to the
dealership to have the campaign completed.
Due to inappropriate programming of the sub-Battery Management Unit (sub-BMU), the subBMU may falsely judge the leak detection circuit as faulty by picking up electrical noises from
operation of the drive selector, brake application, or air conditioner operation. False judgment
of the leak detection circuit may result in several malfunction indicators illuminating, including:
Engine Malfunction, EV System Service Required, and RBS (Regenerative Brake System), with
Diagnostic Trouble Codes (DTCs) P0AA7, P0AA8, and P0AA9 (Leak Sensor Detection Circuit). The
malfunction indicators may be accompanied by a decrease in vehicle power and vehicle speed
being restricted to a maximum of 37 mph (60 km/h). (NOTE: Vehicle power/speed restriction
will be released once the Power switch is turned OFF, then back ON. The malfunction
indicators will stop illuminating after the Power switch is turned OFF and ON several times.)
The Service Campaign Bulletin outlining the repair procedure will be available today on MEDIC
and MDL.
NOTE: The software update associated with this Service Campaign addresses DTC P0AA9 in
addition to DTC P0AA7 & P0AA8. If a vehicle previously received software update based on
TSB-18-54-005, this Service Campaign still applies.
Affected new vehicle inventory VINs can be reviewed on the Mitsubishi Dealer Link in the Most
Recent: Open Campaign List available under the service section of “e-reports” beginning today.
Notification letters will be mailed on October 31, 2018 to owners of affected vehicles,
requesting they contact their local Authorized Mitsubishi dealership to schedule an
appointment to have this service campaign performed.
When checking for applicability of this campaign (C1811R), please check for and complete any
other open campaigns. Always get the customer’s approval before completing a campaign on a
customer-owned vehicle.
IMPORTANT
To maximize customer satisfaction with the quality of their vehicle, affected new or used inventory
vehicles should be remedied before the vehicle is delivered. Dealers must check their inventory
vehicles’ VINs on the Warranty Superscreen to verify whether the vehicle is involved in this service
campaign.
