INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT FUSE (TI & TE)


    1. Remove the TI & TE fuse from the main body ECU RH (cowl side junction block RH).

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      TI & TE fuse Always Below 1 Ω

    NG

    REPLACE FUSE

    OK

  2. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - BATTERY)


    1. A015YJ0E03

      Disconnect the J28 connector from the multiplex tilt and telescopic ECU.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      J28-2 (+B) - Body ground Always 11 to 14 V

    NG

    OK

  3. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - BODY GROUND)


    1. A015YJ0E01

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J28-11 (GND) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - MAIN BODY ECU RH)


    1. A0161VTE02

      Disconnect the RA connector from the main body ECU RH (cowl side junction block RH).

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

      Standard Resistance
      Tester Condition Condition Specified Condition
      J28-2 (+B) - RA-15 Always Below 1 Ω
      J28-2 (+B) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - MAIN BODY ECU RH)

    OK

    REPAIR OR REPLACE HARNESS OR CONNECTOR (BATTERY - MAIN BODY ECU RH (COWL SIDE JUNCTION BLOCK RH))
