DRAINING
1. Stop engine.
2. Remove drain plug (1) and drain gear oil.
3. Set a gasket on drain plug (1) and install it to final drive assem- bly and tighten to the specified torque. Refer to FFD-17, "
COM-
PONENTS (VQ35DE MODELS)" , FFD-19, "COMPONENTS
(VK45DE MODELS)" .
CAUTION:
Do not reuse gasket.
FILLING
1. Remove filler plug (1). Fill with new gear oil until oil level reaches
the specified level near filler plug mounting hole.
2. After refilling oil, check oil level. Set a gasket to filler plug (1), then install it to final drive assembly. Refer to FFD-17, "

PRECAUTIONS

Never reverse polarity of battery terminals.

Install only parts specified for a vehicle.

Before replacing the control unit, check the input and output and functions of the component parts.

Do not apply excessive force when disconnecting a connector.

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.
