    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 connectors disconnected.

      Tester Connection Wiring Color Terminal Description Condition Specified Condition
      2C-24 (BECU) - Body ground L - Body ground Battery power supply Always 11 to 14 V
      2C-30 (ALTB) - Body ground BR - Body ground Battery power supply Always 11 to 14 V
      2F-16 (GND1) - 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 2C and 2F main body ECU (driver side junction block assembly) connectors.
    4. Measure the voltage according to the value(s) in the table below.
      Tester Connection Wiring Color Terminal Description Condition Specified Condition
      D50-24 (DCTY) - Body ground V - Body ground Driver side door courtesy switch input Driver side door open Below 1 V
      D50-24 (DCTY) - Body ground V - Body ground Driver side door courtesy switch input Driver side door closed Pulse generation
