      1. Connect a positive (+) lead from the auxiliary battery to terminal 1 and a negative (-) lead to terminal 2.

      2. Press the AUTO switch.

      3. Attach black colored tape to the forward sensor to prevent it from sensing.

      4. Light up the mirror with an electric light, and check that the mirror surface changes from bright to dark.

        Standard
        Mirror surface changes from bright to dark.

      5. Measure the voltage according to the Value(s) in the table below.

        Standard Voltage
        Tester Connection Condition Specified Condition
        4 - 5

        Inner rear view mirror surface

        Bright → Dark

        		 Below 1 V → 1.25 V

        If the result is not as specified, replace the inner rear view mirror assembly.
