Possible causes are: 1. Vehicle hood is open or safety switch is active. 2. Vehicle brake pedal is pressed or switch is active. 3. Ignition key is resting in the ignition cylinder or the “key chime” circuit is active. 4. Transmission shifter is not in the PARK position. The RES system has detected one of the following operational failures: 1. Remote start has exceeded the maximum 20 minute run time duration between physical ignition key cycles. Cycle ignition key ON then OFF to clear max run timer. OR 2. A vehicle related issue (OTC) is requiring RES to abort operation. Correct vehicle issue and retry activation. Indicates that the RES system was either not registered or not successfully registered to the vehicle using the Subaru Select Monitor tool. 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. 23 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 a vehicle door is opened and shut down via the RES transmitter. Accessing diagnostic mode: 1. Enter the vehicle and close all vehicle doors, trunk or rear gate. 2. Verify that the transmission shifter is in the “park” position. 3. Turn the ignition to the “ON” position 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 (6) ignition key cycles ending in “ON”, total duration from point of second ignition “ON” cycle must not exceed eight (8) seconds.) NOTE: In order to avoid accidentally entering Run Time Selection Mode (see page 22 of this guide), cycle the ignition from OFF to ON six (6) times as quickly as possible. 4. 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 below table. Remote Engine Start Shutdown – Overrev Protection – Video Link Prevent Remote Engine Start – Shifter Out of Park – Video Link Hom 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 the 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) 10 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 (ECU). 24 The RES system will not run for the full default 15-minute run time. Advanced Troubleshooting The RES system will not operate when activated multiple times in a row. The RES system run time is selectable for 3 minutes, 5 minutes, 10 minutes and 15 minutes. Please refer to the vehicle owner’s manual, RES quick reference card or page 22 of this guide for RES system run time selection. A safety feature has been added to the RES system to prevent operation for more than 20 minutes in between physical ignition key cycles. Turning the ignition key to the ON/RUN position and then back off will reset the 20 minute timer. If the 20 minute max duration has been reached in between vehicle ignition key cycles, the vehicle’s horn will honk three (3) times on subsequent remote start activations to alert the user that the max operation time has been reached. 25 The RES system shuts down when any vehicle door, trunk or rear gate is opened. Advanced Troubleshooting The vehicle starts by itself without pressing the RES transmitter button. Remote Engine Start Shutdown – Door Open – Video Link 26 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. Refer to the Installation Instructions Post Installation Checklist for details. Two conditions could exist that would allow the vehicle to start without user interaction with the RES transmitter. 1. Another user’s transmitter was accidently programmed to the RES system and in range of activation. 2. Damage (usually from a severe drop/shock) to the RES transmitter is causing the button to stay engaged or 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 RES system. All customer RES transmitters must be available. Following the transmitter programming procedure on page 22 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” or remove any unauthorized transmitter. – Does this solve the problem? 2. Damage (usually from a severe drop/shock) to the RES transmitter is causing the button to stay engaged or causing a self transmit. If this issue is the cause of the vehicle starting on its’ own, a slight touch or rub of the RES transmitter button would cause it to activate. If this is the case, replace and program the RES transmitter P/N: HOOl SFL020. The SSM IV (DST-i) screen displays “Registration Failure” when attempting to register the RES control module to the vehicle. Advanced Troubleshooting – Are the 8-pin and 12-pin connectors at the RES control module secure? – Are the ignition switch T-connectors properly installed and secure? – Are the vehicle pre-arrangement connectors secure between the RES control module and pre-arrangement connectors? – Verify+ 12 volt battery power at the 8-pin and 12-pin RES module connectors.
