Relation between Illustrations and DescriptionsEAS001TI
The following sample explains the relationship between the part description in an illustration, the part name in
the text and the service procedures.
ComponentsEAS001FI

THE LARGE ILLUSTRATIONS are exploded views (see the following) and contain tightening torques,
lubrication points, section number of the PARTS CATALOG (e.g. SEC. 440) and other information neces-
sary to perform repairs.
The illustrations should be used in reference to service matters only. When ordering parts, refer to the
appropriate PARTS CATALOG .
Components shown in an illustration may be identified by a circled number. When this style of illustration
is used, the text description of the components will follow the illustration.

Do not apply excessive shock to the control unit by dropping or
hitting it.

Be careful to prevent condensation in the control unit due to
rapid temperature changes and do not let water or rain get on it.
If water is found in the control unit, dry it fully and then install it in
the vehicle.

Be careful not to let oil to get on the control unit connector.

Avoid cleaning the control unit with volatile oil.

Do not disassemble the control unit, and do not remove the
upper and lower covers.

When using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit
from damaging battery voltage because of short circuiting.

When checking input and output signals of the control unit, use
the specified check adapter.
SMJ INSTALLATION
To install SMJ, tighten bolts until orange “fulltight” mark appears and
then retighten to specified torque as required.
CAUTION:
Do not overtighten bolts, otherwise, they may be damaged.
