REMOTE ENGINE START CONTROL MODULE REGISTRATION PROCEDURE - SDI/SSMIII

Use of Subaru Diagnostic Interface (SDI) is required.
Verify SSM III (SDI) software is current.

REMOTE ENGINE START CONTROL MODULE REGISTRATION PROCEDURE - DST-I

REMOTE ENGINE START BI-DIRECTIONAL TRANSMITTER PROGRAMMING PROCEDURE

NOTE: Up to eight (8) transmitters can be programmed to the remote engine start system.

Open the driver's door (the driver's door must remain open throughout the entire process).
Depress and hold the vehicle's brake pedal.
Turn the ignition to the "on" and leave on for approximately 2 seconds 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 second ignition "on" cycle must not exceed five (5) seconds)
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.
Press and release the button on the transmitter you wish to program.
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).
Repeat step 5 for any additional transmitters (the system will accept up to eight (8) transmitters).
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 RUN TIME SELECTION

The system is preprogrammed to run for fifteen (15) minutes before automatically stopping. The programmed run period can be changed to alternate times using the following procedure.

Enter the vehicle and close all vehicle doors, trunk or rear gate.
Verify that the transmission shifter is in the "park" position.
Turn the ignition to the "on" and leave on for approximately 2 seconds 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 eight (8) seconds).
The system will honk the horn the number of times corresponding to the current run time setting.
Open and close the driver's door to advance to the next run time setting. The system will honk the horn the number of times corresponding to the new run time setting.

Run time selection mode will exit via turning the ignition key off or thirty (30) seconds of inactivity. Upon exit the current run time selection will be stored.

Horn Honks	Run Time
1	Three (3) Minutes
2	Five (5) Minutes
3	Ten (10) Minutes
4	Fifteen (15) Minutes (Default Setting)

REMOTE ENGINE START ACTIVATION HORN HONK DIAGNOSTICS

When activating the remote engine start system will respond with various horn honk and exterior vehicle light flashes. The sequence of the horn honks/light flashes can help to differentiate between normal and abnormal operation and aid in troubleshooting. Below is a description of the various horn honk/light flash sequences and description of function.

Horn Honk/Light Flash Sequence	System Operation / Failure Mode
One (1) horn honk/light flash immediately after activation from RES fob then one (1) horn honk/light flash following ignition power, starter crank and vehicle start.	Normal operation - Indicates RES system has received remote start request from RES fob, all safety parameters are correct and vehicle has successfully started.
Two (2) horn honks/light flashes immediately after activation from RES fob.	A safety check determined a failure which prevents the system from operating. Possible causes are: Vehicle hood is open or safety switch is active. Ignition key is resting in the ignition cylinder or the "key chime" circuit is active.
One (1) horn honk/light flash immediately after activation from RES fob. Followed by a pause and then two additional horn honks/light flashes.	A safety check determined a failure which prevents the system from operating. Possible causes are: Vehicle hood is open or safety switch is active. Vehicle brake pedal is ON or active. Ignition key is resting in the ignition cylinder or the "key chime" circuit is active. Transmission shifter is not in the PARK position
Three (3) horn honks/light flashes immediately after activation from RES fob.	The RES system has detected one of the following operational failures: Remote start has exceeded the maximum 20 minute run duration between physical ignition key cycles. Cycle ignition key ON then OFF to clear max run timer. OR A vehicle related issue (DTC) is requiring RES to abort operation. Correct vehicle issue and retry activation.
Four (4) horn honks/light flashes immediately after activation from RES fob.	Indicates that the RES system was either not registered or not successfully registered to the vehicle using the Subaru Select Monitor tool.
Five (5) horn honks/light flashes immediately after activation from RES fob.	RES system is in "Service Mode". Refer to the vehicle owner's manual or RES quick reference card for details.
One (1) horn honk/light flash immediately after activation from RES fob. Followed by a pause and then six (6) additional horn honks/light flashes.	Indicates that a vehicle door, trunk or rear gate was open when activating RES. All doors, trunk or rear gate must be closed for RES system to operate.

REMOTE ENGINE START DIAGNOSTIC MODE

The 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. This is particularly helpful in determining a past failure when the system may not be currently exhibiting the observed failure mode. Normal shut downs will not be included in the diagnostic table. Normal shutdowns include: 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:

Enter the vehicle and close all vehicle doors, trunk or rear gate.
Verify that the transmission shifter is in the "park" position.
Turn the ignition to the "on" and leave on for approximately 2 seconds then "off", "on" then "off", "on" then "off", "on" then "off", "on" then "off", then back "on" and leave on throughout the programming process. (Six ignition key cycles ending in "on", total duration from point of second ignition "on" cycle must not exceed eight (8) seconds)

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	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 will not run for the full default 15-minute run time

The RES system run time is selectable for 3 minutes, 5 minute, 10 minutes and 15 minutes. Please refer to the vehicle owner's manual, RES quick reference card or this troubleshooting for RES system run time selection.

The RES system will not operate when activated multiple times in a row

A safety feature has been added to the RES system to prevent operation for more than 20 minutes in between physical ignition key cycles. Cycling the ignition key to the RUN position and then back off will clear the 20 minute timer.

If the 20 minute max duration has been reached in between physical ignition key cycles, the vehicle's horn will honk three (3) times on subsequent activations to alert the user that the max operation time has been reached.

The RES system shuts down when any vehicle door trunk or rear gate 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.

Another user's transmitter accidently programmed to the system and in range of activation.
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.

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 TRANSMITTER PROGRAMMING INSTRUCTIONS of this guide, when you reach step 5, you will program each transmitter multiple times to fill all 8 memory slots. For example, if 2 transmitters are available, program each transmitter four (4) times. This will de-program any unauthorized transmitter.

Does this solve the problem?

NO
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.
If this issue is the cause of the vehicle starting on it's own, a slight touch or rub of the button on the RES transmitter would cause it to activate. If this is the case, the recommended action is to replace the RES transmitter P/N H001SSG460.
