        *a Component without harness connected
        (Map Light Assembly)

        HINT: 

        As the circuit includes a diode, make sure that the polarity of each terminal is correct and diode test mode is selected before connecting the tester.

        Standard Voltage

        Tester Connection Condition Specified Condition
        Tester positive (+) → 15 (RLMP)
        Tester negative (-) → 3 (DOOR)        		 Door linked switch on 0.6V to 1V

        If the result is not as specified, replace the map light assembly.

    2. Resistance Check
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        15 (RLMP) - 11 (GND) Dome light switch on Below 1 Ω

        If the result is not as specified, replace the map light assembly.

    3. Illumination Inspection
      1. Apply auxiliary battery voltage to the map light assembly and check that the lights illuminate.

        OK

        MAP LIGHT LH AND MAP LIGHT RH

        Measurement Condition Condition Specified Condition
        Auxiliary battery positive (+) → 10 (+B1)
        Auxiliary battery negative (-) → 11 (GND)        		 Dome light switch off and map light switch LH on Map light LH illuminates
        Dome light switch off and map light switch RH on Map light RH illuminates
        Map light switch LH and RH off and dome light switch on Map light LH and RH illuminate
        Auxiliary battery positive (+) → 10 (+B1)
        Auxiliary battery negative (-) → 3 (DOOR)        		 Map light switch LH and RH off and door linked switch on Map light LH and RH illuminate
        Map light switch LH and RH off and door linked switch off Map light LH and RH do not illuminate
        Auxiliary battery positive (+) → 10 (+B1)
        Auxiliary battery negative (-) → 15 (RLMP)        		 Map light switch LH and RH off Map light LH and RH illuminate
        Map light switch LH and RH on Map light LH and RH do not illuminate

        OK

        SWITCH ILLUMINATION AND SHIFT LEVER ILLUMINATION

        Measurement Condition Condition Specified Condition
        Auxiliary battery positive (+) → 9 (ILLB)
        Auxiliary battery negative (-) → 2 (LILL)        		 Always Switch illumination and shift lever illumination illuminate

        If the result is not as specified, replace the map light assembly.
