SERVICE INFORMATION BULLETIN
APPLICABILITY: All 2019-22MY Vehicles Equipped with Gen2
NUMBER: 15-281-21R
Telematics
DATE: 3/25/21
SUBJECT:

Customer Takeover after STARLINK Telematics
Remote Engine Start (RES) Request

REVISED:

11/02/21

INTRODUCTION:
This Service Information Bulletin will focus on the Remote Engine Start (RES) takeover process and
potential customer concerns which may arise when taking over operation of the vehicle after starting
it using the Gen2 STARLINK Telematics RES feature.
A SUCCESSFUL RES takeover occurs when the driver possessing a functioning keyless access fob
enters the vehicle through the driver’s door, sits in the driver seat, buckles their seatbelt, depresses
the brake pedal and engages the push-button ignition switch to take control from the RES. The
combination meter center display illuminates “Ready to Drive” and the CVT select lever (shifter) is
now controlled by the driver. A successful Telematics remote engine start (RES) can complete in one
of two ways:
•

The RES timer expires and the engine is off before the customer enters the vehicle.

•

The customer enters the vehicle with the engine still running and attempts to takeover control
of the vehicle before the RES timer expires.

UNSUCCESSFUL RES takeover attempts are explainable and usually result from a specific
sequence of events occurring just before or at the time of the takeover action. Most of the unexpected
behavior can be avoided if the customer follows the standard sequence detailed above describing a
successful RES takeover.
Customer concerns involving an unsuccessful RES takeover may present as:
•

An inability to move the select lever into Drive or;

•

The vehicle does not respond as expected during a takeover attempt which may result in the
customer performing a remote engine stop from the MySubaru APP to takeover control of the
vehicle.

CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles,
or to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
The following scenarios outline root causes of unexpected behaviors which can impede the
customer’s ability to takeover control of the vehicle after a RES request:
1) Key Fob Not Registering Inside of the Vehicle:
As a condition of vehicle takeover during a RES event, just as with a standard push-button ignition,
the keyless access fob must be within the operating range of the vehicle. The following factors may
impede the proper operation of the keyless access fob:
•

A weak keyless access fob battery

•

The presence of aftermarket electronics

•

The use of RFID blocking wallets or handbags.

The keyless access warning indicator (if equipped) will illuminate in the combination meter
simultaneously signaling a failed RES takeover if the fob is not recognized.
Technicians should attempt to duplicate the customer concern of failed RES takeover using ALL
the keyless access fobs the customer has to ensure the expected operation of each. Additionally, the
customer should be asked about the presence of any aftermarket electronics that may be installed
in the vehicle including (but not limited to) OBD II tracking devices, aftermarket power outlets,
aftermarket LEDs, and / or if any RF blocking materials might in use. For example, RFID wallets,
mylar balloons, or “Dynamat®” -type sound-deadening insulation can all impede keyless access fob
operation.
2) Locked Steering Wheel:
A locked steering wheel can prevent RES takeover in the same way it prevents conventional starting
attempts in vehicles equipped with push-button start. A locked steering wheel preventing RES
takeover can be confirmed by a blinking green LED on the push-button ignition switch.
When attempting to duplicate the customer concern of a failed RES takeover due to a locked steering
wheel, Technicians should take note of the push button ignition switch (flashing) LED following a
failed takeover attempt. Once the flashing LED is confirmed, the Technician should attempt RES
takeover by making sure the vehicle is in park, applying the parking brake, firmly depressing the
brake pedal, and wiggling the steering wheel left and right while depressing the push button ignition
switch. If this is successful, the customer should be educated on how to perform this procedure
should the condition occur in the future.
3) Vehicle Not Entered Through Drivers’ Front Door Before RES Takeover Attempt:
A pre-requisite of a successful RES takeover is the operator entering the vehicle through the driver’s
front door. The BIU monitors door lock and door latch operation and passes status messages to
the DCM over the CAN system. Should the driver enter the vehicle through any other door, the
conditions for a successful RES takeover will not be met.

Technicians should attempt to duplicate the customer concern of failed takeover. Once confirmed,
the Technician should monitor the BIU PIDs for the driver’s door latch to ensure it correctly indicates
the driver’s door status. It is unlikely there would be a concern with the driver’s door latch status
because if faulted, it would not meet requirements for a successful RES in the first place. The
customer should be made aware of the requirement to always enter the vehicle through the driver’s
front door and the process for completing a successful vehicle takeover as detailed above.
4) After Entering the Vehicle, the Customer Engages the Key Fob Lock Button But Does
So Before Depressing the Brake Pedal and Push-Button Ignition Switch During A RES
Takeover Attempt:
NOTE: This condition is very rare and is not occurring with any reported frequency. Nonetheless,
it is mentioned here to address the possibility this customer behavior may be a root cause of the
concern.
In a rare case where the customer enters a vehicle under RES control then uses the keyless access
fob to lock the vehicle doors before depressing the brake pedal and pressing the push-button ignition
switch, RES takeover will fail. There is logic in the keyless access control module (KCAM) causing
this behavior which is a NORMAL operating characteristic. There should be no attempt to repair
this condition. The Technician should explain to the customer their actions are impeding the
successful RES takeover procedure detailed above. Taking the time to explain this procedure will
help the customer avoid this condition during future takeover attempts.
5) One More Possible Source of Customer Concern:
Customers who experience a failed RES takeover may react to the situation differently to takeover
vehicle control. Once inside the vehicle and experiencing a failed takeover, the customer could
wait for the RES timer to expire. They are then essentially performing a standard engine start up
procedure by engaging the brake pedal and depressing the push-button ignition switch. Another way
to takeover control would be to use the MySubaru APP and perform a remote engine stop which
immediately expires the RES timer and stops the engine. Again, the customer would perform the
standard engine start procedure and taking control.
Customers may unintentionally perform a long press of the pushbutton starter during the takeover
procedure. This long press would have to be three seconds or more before the push-button start
system will shut the running engine off. A customer doing this will also get an error message
indicating “Remote Service has stopped abnormally.” At this point, the customer can perform
the standard engine start procedure and takeover the vehicle. Technicians should be mindful of
customers reporting this error message as it may be accidentally caused by the customer or, indicate
a possible RES takeover failure. Take this opportunity to duplicate the conditions under which the
error message occurred and educate the customer on the successful RES takeover procedure detailed
above.
IMPORTANT REMINDERS:
•

SOA strongly discourages the printing and/or local storage of service information as previously
released information and electronic publications may be updated at any time.

•

Always check for any open recalls or campaigns anytime a vehicle is in for servicing.

•

Always refer to STIS for the latest service information before performing any repairs.
