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 five 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:
|
| 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:
|
| Three (3) horn honks/light flashes immediately after activation from RES fob. | The RES system has detected one of the following operational failures:
|
| 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) 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 H001SAL010.
