(f) Check the outer mirror operation, as shown in the illustra-
tion.
(1) Push the retract switch from the (B) position to the
(A) position.
(2) Check that the right and left mirrors move from the
retracted position to the driving position.
(g) Check the outer mirror operation, as shown in the illustra-
tion.
(1) Move one of mirrors to the driving position by hand.
(2) Push the retract switch From the (A) position to the
(B) position.
(3) Check that the other mirror moves from the re-
tracted position to the driving position.
(h) Check operation of the outer mirror body when the igni-
tion switch is turned OFF during operation.
(1) When turning the ignition switch OFF during opera-
tion of the mirror body, check that the mirror body
operation stops.
(2) Check that the mirror body continues to operate
when the ignition switch is turned to ACC again.
HINT:
If the retract switch is switched while the ignition switch is OFF
and the ignition switch is turned to ACC again, the mirror body
will operate in the opposite direction.
(i) Check operation of the outer mirror body when it is re-
strained by an obstacle.
(1) Check that operation stops when restraining the
mirror body movement by hand while the mirror
body is moving to the retraced position or the driving
position.
(2) Switch the retract switch under the above condition,
and check that the mirror body starts operation
again to the opposite direction.

Freeze frame data:
Freeze frame data records the engine conditions
(fuel system, calculator load, water temperature,
fuel trim, engine speed, vehicle speed, etc.) when
a malfunction is detected. When troubleshooting,
it is useful for determining whether the vehicle was
running or stopped, the engine was warmed up or
not, the air±fuel ratio was lean or rich, etc. at the
time of the malfunction.
(c) Check the DLC3.
The vehicle's ECM uses the ISO 9141±2 (Euro±OBD)/
ISO 14230(M±OBD) communication protocol. The termi-
nal arrangement of DLC3 complies with ISO 15031±03
and matches the ISO 9141±2/ ISO 14230 format.

HINT:
If the display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the hand±held tester to
the DLC3, turned the ignition switch ON and operated the
hand±held tester, there is a problem on the vehicle side or tool
side.

If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.

If communication is still not possible is when the tool is
connected to another vehicle, the problem is probably in
the tool itself, so consult the Service Deparment listed in
the tool's instruction manual.
(d) Inspect the battery voltage.
Battery voltage: 11 to 14 V
If voltage is below 11V, recharge the battery before proceeding.
(e) Check the CHK ENG.
(1) The CHK ENG lamp comes on when the ignition
switch is turned ON and the engine is not running.
HINT:
If the CHK ENG lamp is not illuminated, troubleshoot the com-
bination meter.
(2) When the engine is started, the CHK ENG should
go off. If the lamp remains on, it means that the diag-
nosis system has detected a malfunction or ab-
normality in the system.

BASIC INSPECTION
When the malfunction is not confirmed in the DTC check, troubleshooting \
should be carried out in all the
possible circuits considered as causes of the problem. In many cases, by carrying out the basic engine check
shown in the following flow chart, the location causing the problem can be found quickly and efficiently.
Therefore, using this check is essential in the engine troubleshooting.
1CHECK BATTERY VOLTAGE
NOTICE:
Carry out this check with the engine stopped and ignition switch off. Reference:

mal even if the measured values are a little different from those listed here. Do not decide whether
a part is faulty or not solely according to the ºNormal Conditionº here.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the Hand±held tester to the DLC3.
