SERVICE PROCEDURE FLOWCHART

SERVICE PROCEDURE INFORMATION

STEP 1:  Turn off vehicle electrical systems to reduce electrical load.

• Turn off all electrical accessories (i.e., climate control, audio-navigation system, etc.).
• Set headlight switch to DRL OFF position.
• Set windshield wiper switch to OFF position.
• Set driver easy exit seat slide function to OFF position.
• Confirm all exterior lighting systems are off.
• Turn off interior lighting systems (confirm that no light comes on even if a door is opened)
• Disable the seat belt warning system (this can be turned off via the buckle switch).
• Turn off the seat heaters and/or ventilation system (only for the vehicle to which it is equipped).
• Disable the rain sensing function (only for the vehicle to which it is equipped).
• Confirm the rear defogger system is off.
• Confirm the steering wheel heater is off (only for the vehicle to which it is equipped).
• Disable any additional/aftermarket accessories (security system, etc.).

STEP 2:  Inspect vehicle 12v auxiliary battery condition and connect power supply.

Push the power switch without  pressing brake pedal (Power-ON), wait at least 1 minute then confirm battery voltage is at least 12.0 Volts. If the battery is below 12.0 Volts, charge the battery before performing reprogramming. Subaru of America, Inc. (SOA) highly recommends utilizing the Subaru Midtronics DCA8000 Dynamic Diagnostic Charging System. Once the DCA8000 is connected and the battery is fully charged, restart the charger and select Power Supply Mode. The battery voltage will be stabilized and ready for reprogramming.

BATTERY CHARGER NOTES

• For instructions on using the Power Supply Mode, reference the applicable User Manual for the Midtronics DCA-8000 Dynamic Diagnostic Charging on STIS.
• Select the correct battery type (Enhanced Flooded, Flooded, Gel, AGM, or AGM Spiral).
• Input the CCA which matches the vehicle's battery.
• If using a DCA-8000 Dynamic Diagnostic Charging System, set the power supply voltage to 13.5 Volts.
• DO NOT connect the GTS+ until the Power Supply mode function has completed its battery test mode and the Charging Voltage has dropped to and shows a steady 13.5 Volts on the display.
• Once Power Supply Mode reaches a steady 13.5 Volts, connect the GTS+ to the OBD connector and proceed with initiating the normal reprogramming process.
• Amperage will fluctuate based upon the vehicle's demand for power.
  NOTE: If the voltage rises beyond 14 Volts while programming is in process, the procedure will abort. This can indicate a need to test or charge the vehicle battery before any further attempt at programming is made.
• ALWAYS set the power supply voltage to 13.5 Volts when using Power Supply Mode. NEVER turn the ignition switch on when charging at voltages 15 Volts or higher.
• Control module failures resulting from battery discharge during reprogramming are not a matter for warranty. Should any DTCs reset after the reprogramming update is performed, diagnose per the procedure outlined in the applicable Service Manual.

REMINDER:  If the DCA-8000 indicates the vehicle's battery must be charged, charge the battery fully before proceeding to reprogram the vehicle while using the Power Supply Mode.

STEP 3:  Stabilize the power supply to Global TechStream Plus (GTS+).
