REMOTE ENGINE START CONTROL MODULE REGISTRATION PROCEDURE - 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" 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)
- 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 fl ash 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 fl ash 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 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):
- 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" 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)
- The system will fl ash 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.
- Release the brake pedal and then immediately press and release the brake pedal again.
- The system will fl ash 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. |
