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

      Tester Connection Wiring Color Terminal Description Condition Specified Condition
      R6-5 (B) - R6-7 (E) L - W-B +B Power supply Always 11 to 14 V
      R6-6 (IG) - R6-7 (E) V - W-B Engine switch power supply Engine switch off Below 1 V
      R6-6 (IG) - R6-7 (E) V - W-B Engine switch power supply Engine switch on (IG) 11 to 14 V
      R6-7 (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 R6 ECU connector.

    4. Measure the voltage according to the value(s) in the table below.

      Tester Connection Wiring Color Terminal Description Condition Specified Condition
      R6-9 (OPN) - R6-7 (E) B - W-B Sliding roof motor open Engine switch on (IG), SLIDE OPEN switch ON Below 1 V
      R6-9 (OPN) - R6-7 (E) B - W-B Sliding roof motor open Engine switch on (IG), SLIDE OPEN switch OFF 11 to 14 V
      R6-8 (CLS) - R6-7 (E) SB - W-B Sliding roof motor close Engine switch on (IG), SLIDE CLOSE switch ON Below 1 V
