CONSULT Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch OFF.
2) Connect CONSULT to Data Link Con- nector for CONSULT.
1) Start engine.
2) Drive vehicle over 30 km/h (19 MPH) for at least one minute.
1) Stop vehicle with engine runningand touch ``START'' on CONSULT
screen.
2) Touch ``ABS''.
3) Touch ``SELF-DIAG RESULTS''.
+ The screen shows the detected mal-
function and how many times the igni-
tion switch has been turned since the
malfunction.
Make the necessary repairs following the
diagnostic procedures.
After the malfunctions are repaired, erase
the self-diagnostic results stored in the
control unit by touching ``ERASE''.
Check warning lamp for deactivation after
driving vehicle over 30 km/h (19 MPH) for
at least one minute.
Test the ABS in a safe area to verify that it
functions properly.

Body Front End
+When removing or installing hood, place a cloth or other padding on front fender panel and cowl top. This
prevents vehicle body from being scratched.
+Bumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
+Hood adjustment: Adjust at hinge portion.
+Hood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
+Hood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.
REMOVAL Ð Front bumper assembly
V1Remove front guard bar. Refer to ``EXTERIOR'' for details, BT-26.
V2Remove left and right headlamp wipers (on models with headlamp wipers).
V3Remove clips securing front grille and remove the front grille.
V4Remove screws and bolts securing left and right front bumper side bracket.
V5Remove bolts securing bumper lower to engine under cover.
V6Remove bolts securing left and right front bumper stay upper (without winch).
V7Remove bolts securing left and right front bumper stay side.
V8Extract bumper assembly.

+All dimensions indicated in ®gures are actual ones.
+When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge
itself to make sure there is no free play.
+When a measuring tape is used, check to be sure there is no elongation, twisting or bending.
+Measurements should be taken at the center of the mounting holes.
+An asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.
+The coordinates of the measurement points are the distances measured from the standard line of ``X'', ``Y''
and ``Z''.

INSPECTION
Hoses and connectors
+Check condition of vacuum hoses and connections.
+Check vacuum hoses and check valve for air tightness.
Vacuum hose check valve
1. Remove the vacuum hose.
2. Blow air through one end (booster side) of the vacuum hose
and make sure that air passage continuity exists.
3. Blow air through the other end (engine side) of the vacuum
hose and make sure that air passage continuity does not exist.
Check valve
1. Remove the vacuum hose.
2. Check the condition of the check valve using a handy vacuum
pump.

Precautions
+Before connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
+When connecting ECM harness connector, tighten secur-
ing bolt until the gap between orange indicators disap-
pears.
: 3.0 - 5.0 Nzm (0.3 - 0.5 kg-m, 26 - 43 in-lb)
+When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
+Before replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-54.
+If MIL illuminates or blinks irregularly when engine is
running, water may have accumulated in fuel ®lter. Drain
water from fuel ®lter. If this does not correct the problem,
perform speci®ed trouble diagnostic procedures.
+After performing each TROUBLE DIAGNOSIS, perform
``OVERALL FUNCTION CHECK'' or ``DTC (Diagnostic
Trouble Code) CONFIRMATION PROCEDURE''.
The DTC should not be displayed in the ``DTC CONFIRMA-
TION PROCEDUREº if the repair is completed. The ``OVER-
ALL FUNCTION CHECK'' should be a good result if the
repair is completed.
