INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT FUSES (ECU-B, PSD LH, LH ECU-IG)


    1. Remove the PSD LH and LH ECU-IG fuses from the driver side junction block assembly.*1

    2. Remove the PSD LH and LH ECU-IG fuses from the passenger side junction block assembly.*2


      • *1: for LHD

      • *2: for RHD

    3. Remove the ECU-B fuse from the no. 1 engine room relay block.

    4. Measure the resistance of the fuses.

      Standard Resistance
      Below 1 Ω

    NG

    REPLACE FUSE

    OK

  2. CHECK HARNESS AND CONNECTOR (ECU LH - BATTERY AND BODY GROUND)


    1. Reinstall the PSD LH and LH ECU-IG fuses to the driver side junction block assembly.*1

    2. Reinstall the PSD LH and LH ECU-IG fuses to the passenger side junction block assembly.*2


      • *1: for LHD

      • *2: for RHD

    3. Reinstall the ECU-B fuse to the no. 1 engine room relay block.

    4. A01CFVTE03

      Disconnect the N16 power slide door ECU LH connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      N16-12 (ECUB) - Body ground Always 11 to 14 V
      N16-4 (IG) - Body ground Engine switch on (IG) 11 to 14 V
      N16-7 (B) - Body ground Always 11 to 14 V

    6. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      N16-1 (GND) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
