PROCEDURE


  1. INSPECT FUSE (TI & TE)


    1. Remove the TI & TE fuse from the main body ECU.

    2. Measure the resistance of the fuse.

      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. A001AV5E03
      *1 Rear view of wire harness connector: (to Multiplex Tilt and Telescopic ECU)

      Disconnect the L34 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
      L34-2 (+B) - Body ground Always 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

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


    1. A0019ACE05
      *1 Rear view of wire harness connector: (to Multiplex Tilt and Telescopic ECU)

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

      Standard resistance
      Tester Connection Condition Specified Condition
      L34-11 (GND) - Body ground Always Below 1 Ω

    OK
