Remote Engine Start Bi-directional Transmitter Programming Procedure
NOTE: Up to eight (8) transmitters can be programmed to the remote engine start system.
1. Open the driver’s door (the driver’s door must remain open throughout the entire process).
2. Depress and hold the vehicle’s brake pedal.
3. Turn the ignition to the “on” then “off”, “on” then “off”, “on” then “off”, then back “on” and leave “on” throughout the
programming process. (Four ignition key cycles ending in “on”, total duration from point of first ignition “on cycle
must not exceed five (5) seconds)
4. The system will flash the side marker lights, tail lights, front position lights and honk the horn three (3) times,
indicating that the system has entered transmitter learn mode.
5. Press and release the “
“ button on the transmitter you wish to program.
6. The system will flash the side marker lights, tail lights, front position lights and honk the horn one (1) time,
indicating that the system has learned the transmitter. Upon successful programming, the remote start confirming
transmitter button will flash one (1) time (within five (5) seconds).
7. Repeat step five (5) for any additional transmitters (the system will accept up to eight (8) transmitters).
8. The system will exit transmitter programming mode if the ignition key is turned to the OFF position, the door is
closed or after two (2) minutes.

Remote Engine Start Diagnostic Mode
The Forester remote engine start module is equipped with a diagnostic mode that will aid in troubleshooting abnormal failure to start or
abnormal shut down conditions. The diagnostic mode saves the last abnormal failure to start or abnormal shut down in memory.
Normal shut downs will not be included in the diagnostic table. Normal shutdowns include: 15-minute run time expiration, shut down or
failure to start when the vehicle door is opened, shut down via RES transmitter and failure to start when the service mode is active.
Accessing diagnostic mode (same as transmitter learn mode):
1.
Open the driver’s door (the driver’s door must remain open throughout the entire process).
2.
Depress and hold the vehicle’s brake pedal.
3.
Turn the ignition to the “on” then “off”, “on” then “off”, “on” then “off”, then back “on” and leave “on” throughout the programming
process. (Four ignition key cycles ending in “on”, total duration from point of first ignition “on cycle must not exceed five (5) seconds)
4.
The system will flash the side marker lights, tail lights, front position lights and honk the horn three (3) times, indicating that the
system has entered transmitter learn mode.
5.
Release the brake pedal and then immediately press and release the brake pedal again.
6. The system will flash the side marker lights, tail lights, front position lights and honk the horn a number of times
corresponding with the table below.
Horn Honks
12
Shutdown Condition
Diagnosis
No Honk
Normal Operation
Normal remote start operation. No abnormal shut downs
have occurred since installation of the system.
1 Honk
Hood Safety Switch Active
Verify that hood is closed and latched. Check for damaged
or mis-aligned hood switch/bracket.
2 Honks
Brake Pedal Depressed
Check for damaged or inop brake switch in vehicle or
connection issue between BIU and brake pedal switch. This
does not indicate failure of an RES component.
3 Honks
RES Stop Request
The vehicle's BIU sent a "stop request" to the RES module
to indicate a vehicle related concern (DTC's, etc.). Vehicle
condition must be corrected prior to restoring RES operation.
This does not indicate failure of an RES component.
Contact SOA for a listing of conditions and DTC's that would
cause the BIU to transmit an "RES Stop Request" message.
4 Honks
RPM Over-rev
The RES module reads a CAN message to determine
engine speed (> 3,500 RPM). Check vehicle systems to
determine what would cause an abnormal high RPM. This
does not indicate failure of an RES component.
5 Honks
Missing CAN Messages
The RES system detected missing CAN Bus messages
from the BIU or TCU. Verify proper operation of both BIU
and TCU. This does not indicate failure of an RES
component.
6 Honks
Shifter Not in Park
This indicates that the shifter was not in park at time of
RES activation or was moved out of park after RES
activation. Verify operation of transmission/shifter switches.
Verify operation of the BIU and TCU. This does not indicate
failure of an RES component.
7 Honks
CAN Error
This fault indicates that the RES module recorded 24 or
more CAN error messages. Clear any vehicle DTC's that
are present and re-test. If DTC's continue to occur, remove
the (2) 30 AMP fuses from the RES main harness. If DTC's
return, there is an issue with another vehicle component.
If DTC's do not return or return only when RES system is
running the vehicle, replace the RES control module
p/n H001SFJ010.
Advanced Troubleshooting
The RES system shuts down when any vehicle door (or rear gate on 5-door vehicles) is opened.
- This is an additional safety feature and is normal
operation.
Note: The vehicle will continue to run if the trunk is
opened on sedan vehicles.
The vehicle starts by itself without pressing the transmitter button
Two conditions could exist that would allow the vehicle to
start without user interaction with the RES transmitter.
1. Another user’s transmitter accidently programmed to
the system and in range of activation.
2. Damage (usually caused by severe drop/shock) to
the RES transmitter that is allowing the button to stay
engaged or damage causing a self transmit.
1. Another user’s transmitter accidently programmed to
the system and in range of activation.
To correct this situation, the unauthorized transmitter
must be de-programmed from the system. All customer
RES transmitters must be available. Following the
