INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT FUSE (D/C CUT, MPX-B)


    1. Remove the D/C CUT and MPX-B fuses from the engine room relay block and junction block No. 1.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D/C CUT fuse Always Below 1 Ω
      MPX-B fuse Always Below 1 Ω

    NG

    REPLACE FUSE

    OK

  2. CHECK COWL SIDE JUNCTION BLOCK RH (POWER SOURCE)


    1. Install the D/C CUT and MPX-B fuses to the engine room relay block and junction block No. 1.

    2. A0163I1E01

      Disconnect the RK cowl side junction block RH connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      RK-5 (+B) - Body ground Always 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU RH (COWL SIDE JUNCTION BLOCK RH))


    1. A0163JBE01

      Disconnect the RD and RA cowl side junction block RH connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      RD-7 (E) - Body ground Always Below 1 Ω
      RA-5 (-S) - Body ground Always

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
