    2. Measure the voltage and resistance according to the value(s) in the table below.

      HINT: 

      Measure the values on the wire harness side with the connector disconnected.

      Tester Connection Wiring Color Terminal Description Condition Specified Condition
      J19-1 (IG) - J19-5 (E) LG - W-B IG power supply Engine switch off Below 1 V
      J19-1 (IG) - J19-5 (E) LG - W-B IG power supply Engine switch on (IG) 11 to 14 V
      J19-5 (E) - Body ground W-B - Body ground Ground Always Below 1 Ω

      If the result is not as specified, there may be a malfunction in the wire harness.

    3. Reconnect the J19 rear sunshade relay connector.
    4. Measure the voltage according to the value(s) in the table below.
      Tester Connection Wiring Color Terminal Description Condition Specified Condition
