WARNING: This page is about a different car, the 2018 Subaru BRZ. However, it is still accessible from the selected car via links, so may be relevant.
  1. Initialization procedure for the headlight leveling computer ASSY
    CAUTION: Perform initialization using the following procedure when removing, installing, or replacing the height control sensor RR LH, when performing a procedure that changes the height of the vehicle, such as replacing the suspension, and when replacing the headlight leveling computer ASSY.
    NOTE: When initializing the headlight leveling computer ASSY, the amount of fuel shown on the scales of the fuel receiver gauge is broken into 5 levels, and processing is performed based on the amount of fuel at that time.
    1. Checking the vehicle condition
      1. Put the vehicle in the following condition.
        • Remove any loadable luggage from the vehicle. (The spare tire and on-board tools are mounted on the vehicle.)
        • There are no passengers in the vehicle.
        • Turn off the headlights.
        • Vehicle is stopped, and the vehicle height does not change. (Vehicle posture is stable on a level surface.)
          NOTE: Initialization cannot be normally performed unless above-mentioned conditions are all satisfied.
    2. Checking the warning display
      1. 3 seconds after IG OFF →ON, check the warning display of the headlight leveling warning light in the combination meter ASSY.
        OPERATION CONTENTS DESCRIPTION - CRITERIA

        Operation contents Warning display
        Replacement (new one) or initialization error of the headlight leveling computer ASSY Continues blinking 6 times at 2 Hz
        Replacement or removal/installation of the height control sensor RR LH, or suspension replacement, etc. OFF
        NOTE: If it is outside the specification, check the headlight leveling computer ASSY, the height control sensor RR LH, and the wiring harnesses and connectors.
    3. Initialization operation
      1. Turn the ignition switch to ON.
      2. Using the SST, short-circuit 1 (LVL) to 4 (CG) of DLC3.

      3. Based on the position of the indicator of the fuel receiver gauge (amount of remaining fuel), determine the applicable number of times to operate the light control switch using the following chart.
        INDICATOR POSITION DESCRIPTION

        Remaining amount in the scales Number of times to operate the light control switch
        Indicator is in range A 1 time
        Indicator is in range B 2 times
        Indicator is in range C 3 times
        Indicator is in range D 4 times
        Indicator is in range E 5 times

      4. After short-circuiting the initialization terminals, turn the light control switch OFF →HEAD →OFF for the number N(*2)of times.
        NOTE:
        • *2: N is the number of times to operate the light control switch determined based on the position of the indicator of the fuel receiver gauge.
        • Start operating the switch within 20 seconds after short-circuiting the initialization terminals.
        • Operate the switch approx. at 3-second intervals.
      5. After operating the light control switch, check the warning display 3 seconds later.
        Operation contents Warning display Result
        Replacement of the headlight leveling computer ASSY (new) Blinks 6 times at 2 Hz →Continues blinking N((1)) times at 2 Hz Initialization completed normally
        Continues blinking 6 times at 2 Hz Initialization error
        Replacement or removal/installation of the height control sensor RR LH, or suspension replacement, etc. No blinking →Continues blinking N((1)) times at 2 Hz Initialization completed normally
        Continues blinking 6 times at 2 Hz Initialization error
        NOTE:
        • (1) N is the number of times the light control switch was operated.
        • For initialization errors, the headlight leveling warning light in the combination meter ASSY turns on.
        • If the number of times the warning light blinks and the number of times the switch was operated are different, initialization was not completed normally.
        • If it was not completed normally (initialization error), start over from (*1).
      6. Once the normal completion of the initialization is confirmed, turn the ignition switch to OFF.
        NOTE: Blinking from initialization completing normally continues until IG OFF.
