HINT:
When a signal enters the ECU to LOCK the front dif ferential and
set the rear differential to FREE (when battery positive voltage
is inputted to terminal 6 (RF) of ECU and about 0 V is inputted
to terminal 12 (R)), or a signal to FREE both the front and rear
differentials, the indicator lights keep blinking until the ignition
switch is turned off (Fail−safe function).
If the circuit is not as specified, check and repair or replace the
trouble part shown in the table above.
(b) Inspect the battery positive voltage Battery positive voltage: 10 − 14.5 V
(c) Inspect the system circuit with connector connected (1) Turn the ignition switch to the ON position.
(2) Keep the center Diff. lock condition.
(3) Remove the Diff. lock ECU.
(4) Using a voltmeter, measure the voltage when thedifferential lock control switch is in the position, as
shown below.
