CAUTION / NOTICE / HINT

Tech Tips

When the main body ECU (multiplex network body ECU) is replaced, the automatic light control system will not function until the engine is started.

PROCEDURE


  1. INSTALL MULTIPLEX NETWORK BODY ECU (MAIN BODY ECU)

    Note


    • If the multiplex network body ECU (main body ECU) is replaced, replace it with a new one.

    • Make sure that no foreign matter gets on the connecting surfaces.

    • Do not touch the ECU connector.


    1. A01V8SEC01
      *1 Housing Sidewall
      *a 20°

      Insert the multiplex network body ECU (main body ECU) up to the position where it contacts the housing sidewall of the guide as shown in the illustration.

      Tech Tips

      Make sure to keep the angle 20° or more as shown in the illustration.

    2. A01V7KQC01
      *1 Housing Sidewall
      *2 Junction Block Fuse

      Slide the guide of the multiplex network body ECU (main body ECU) along the housing sidewall so that it contacts the junction block fuses as shown in the illustration.

    3. A01V7R0C01
      *1 Side A Contact Portion

      While keeping the multiplex network body ECU (main body ECU) in contact with side A of the junction block (axis of rotation), rotate it downward as shown in the illustration.

    4. A01V7TVC01
      *1 Push Area

      Press the push area until the claw engages to install the multiplex network body ECU (main body ECU).

      Note


      • Make sure to press only the push area.

      • Confirm the engagement of the multiplex network body ECU (main body ECU) and junction block by listening for the lock sound.

      Tech Tips

      If a lock sound cannot be heard, visually check the lock part engagement. The engagement can also be confirmed if the multiplex network body ECU (main body ECU) and junction block are flush.

  2. INSTALL INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY


    1. Install the instrument panel junction block assembly with the bolt and 2 nuts.
