(c) Turn ignition switch to LOCK, and wait at least 20 se-
conds.
(d) Turn ignition switch to ACC or ON, and wait at least 20 se-
conds.
(e) Using SST, connect terminals Tc and E1 of DLC1.
SST 09843−18020
(f) Check DTC.
OK:
DTC 12 is not output.
HINT:
Codes other than code 12 may be output at this time, but they
are not relevant to this check.
NG Replace front passenger airbag assembly.
OK
From the results of the above inspection, the malfunctioning part can now be \

to the air filter side freely.
(c) Start the engine, and maintain speed at 2,500 rpm.
(d) Repeat the above test. Check that there is a strong resis-
tance to air flow.
If operation is not as specified, replace the EGR vacuum modu-
lator.

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.
