Push Area


i.

Set the main body ECU (multiplex network body ECU) to the position where the guide of the main body ECU (multiplex network body ECU) contacts the housing sidewall of the instrument panel junction block assembly as shown in the illustration.

NOTICE:

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



ii.

Slide the main body ECU (multiplex network body ECU) along the housing sidewall as shown in the illustration and engage the guides.


iii.

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


iv.

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

NOTICE:
·

Make sure to press only the push area.

·

Confirm the engagement of the main body ECU (multiplex network body ECU) and instrument panel junction block assembly by listening for the click sound of the lock engaging.

·

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