Malfunction Indicator (MI)EBS0036Q
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
lIf the MI does not light up, refer toDI-39, "WARNING LAMPS"
or seeEC-825.
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
On Board Diagnostic System Function
The on board diagnostic system has the following two functions.
Diagnostic Test Mode I - Bulb Check
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer toDI-39,
"WA RN ING LA MPS"or seeEC-825.

INTAKE MANIFOLD
Tightening Intake Manifold collector bolts and nuts
lTighten in numerical order as shown in the figure.
NOTE:
No.6 means double tightening of bolts 1.
Installation of Electric Throttle Control Actuator
lTighten fixing bolts of electric throttle control actuator equally and diagonally in several steps.
lAfter installation perform procedure inEM-20, "INSPECTION AFTER INSTALLATION".
Connecting Quick Connector of Fuel Hose
lInstall quick connector as follows. (The steps are the same for quick connectors on engine side and vehi-
cle)
1. Make sure no foreign substances are deposited in and around tube and quick connector and no damage
on them.
2. Thinly apply new engine oil around the fuel tube tip end.
3. Align center to insert quick connector straightly into fuel tube.
lInsert fuel tube into quick connector until the first spool on fuel
tubes is inserted completely and the second one is positioned
slightly below the quick connectors bottom end.
CAUTION:
lHold A position in illustration when inserting fuel tube
into quick connector.
lCarefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
lInsert until you hear a “click” sound and actually feel the
engagement.
lTo avoid misidentification of engagement with a similar sound, be sure to perform the next step.
4. Before clamping fuel hose with hose clamps, pull quick connector hard by hand holding A position. Make
sure it is completely engaged (connected) so that it does not come out from fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
5. Install quick connector cap on quick connector joint.
lDirect arrow mark on quick connector cap to upper side (The
figure shows quick connector cap for engine side).
6. Install fuel hose to hose clamp.
INSPECTION AFTER INSTALLATION
lCheck connections for fuel leakage.
1. Start the engine, and run it for a few minutes with engine at idle.
2. Stop the engine, and check for fuel leakage both visually and by odor of gasoline.
NOTE:
Use mirrors for checking on invisible points.

PRIMARY TIMING CHAIN
INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks and excessive wear at roller links. Replace
chain if necessary.
INSTALLATION
1. Install rear chain case.
a. Apply a continuous bead of Genuine Liquid Gasket or eqivalent
on locations shown in the figure. Refer toEM-103, "
Precautions
for Liquid Gasket".
A: Apply bead so that it does not protrude into the oil passage.
B, C: Minimize overlapping area of bead, by starting and ending
at areas of bead as shown in the figure. Apply so that the portion
marked * comes at an external location but cannot be viewed
externally after engine assembly.
D: Leave the start and end areas of the bead slightly protruding
from the case surface.

lVehicle vibration
lHeat sensitive
lFreezing
lWater intrusion
lElectrical load
lCold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
Vehicle Vibratio n
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustra-
tion.
CONNECTORS & HARNESS
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
HINT
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
SENSORS & RELAYS
Gentlyapply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
ENGINE COMPARTMENT
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
lConnectors not fully seated.
lWiring harness not long enough and is being stressed due to engine vibrations or rocking.
lWires laying across brackets or moving components.
lLoose, dirty or corroded ground wires.
lWires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the
wiring for continuity.

Trouble Diagnoses
EKS003CF
Aiming AdjustmentEKS003CG
When performing headlamp aiming adjustment, use an aiming machine, aiming wall screen or headlamp
tester. Aimers should be in good repair, calibrated and operated in accordance with respective operation man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.
lKeep all tires inflated to correct pressures.
lPlace vehicle and tester on one and same flat surface.
lSee that there is no-load in vehicle (coolant, engine oil filled up to correct level and full fuel tank) other
than the driver (or equivalent weight placed in driver's position).
