Terminal Relay
Terminal relays control operation of the diff-
lock, rotation of the rotary knives, 2WD/4WD
selection and traction assist selection.
The operating condition can be checked by the
illumination of the LEDs.
Two terminal relays of four circuits each are
used.

Inspection of Terminal Relay
Have ready a simple terminal relay.
It is normal that there is conduction
between terminals 5 and 9 of the terminal
relay.

Caution
Do not short-circuit the battery terminals.
It is normal that there is conduction
between 9 and 13 and LED1 lights up with
the battery connected between COM and 1.

Inspection of Power Relay
Note:
All the power relays have the same internal
circuits. Accordingly the inspection method
should be the same.
Disconnect the power relay from the
terminal relay.
The normal measured resistance between
relay terminals 1 and 8 is about 480 Ω.
