INSPECTIONCAMSHAFT
h(1) Visually check the camshaft journal surfaces and replace if
_damage or seizure is evident.
If the journal is seized, check the cylinder head for possibledamage. Check also for clogged oil holes in the cylinder
head.
(2) Check cams for excessive wear and damage and replace if
defects are evident. Measure the cam height and replace ifthe limit is not reached.

ROCKER ARM
(1) Visually check the roller and replace if dent, damage, or
seizure is evident.
(2) Check the roller for smooth rotation. Replace if it binds or
there is an excessive play.
(3) Check the valve contact surface for possible damage or
seizure and replace as necessary.
SERVICE POINTS OF REASSEMBLYNOSLGAB10. INSTALLATION OF CAMSHAFT
(1) Apply engine oil to journals and cams of the camshafts.
(2) Install the camshafts on the cylinder head.
Use care not to confuse the intake camshaft with the
exhaust one. The intake camshaft has a slit on its rear
end for driving the crank angle sensor.
(3) Make also sure that the dowel pins on the camshaft
sprocket end are located on the top.

(1) Bearing cap Nos.2 to 5 are of the same shape. At
installation, check with the markings on the caps of capnumber and intake/exhaust identification symbol. Only

TROUBLESHOOTING
When checking and correcting engine troubles, it is
important to start with inspection of the basic
systems.
In case you have such troubles as (1) engine start
failure, (2) rough idling or (3) poor acceleration,
therefore, you should first check the following basic
systems:
(1) Power supply
0 Batteryl
Fusible linkl
Fuse
(2) Body ground
(3) Fuel supplyl
Fuel linel
Fuel filter
l
Fuel pump

(4) Ignition systeml

0 Ignition coil
(5) Emission control systeml
Crankcase ventilation systeml
Exhaust gas recirculation systeml

(6) Others
0 Ignition timing

Idle speed
Troubles with the MPI system are often caused by
poor contact of harness connector. It is, therefore,
important to check harness connector contact.

Auto-cruisecontrol unitDescription of operation
When the SET switch is switched ON (at the vehicle speed
desired to be maintained, and with the CRUISE switch of the
cruise-control switches ON) that vehicle speed is maintained as
a constanf speed.
Furthermore, the constant speed is gradually reduced (the
“coasting” feature) when the SET switch is pressed and held
while the vehicle is traveling at the previously set constant
speed, and, when the SET switch is released, the vehicle then
maintains that newly set constant speed (the speed at whichthe SET switch was released).
Current flows to the control unit, the cruise control switch
(“SET”), and to ground.Troubleshooting hint

Sub fusible link @
vacuum
w-vStop light
Auto-cruisecontrol unit13A0366Description of operation
When the brake pedal is depressed during constant-speedtravel, the stop light switch’s (NC) contacts for the cruise-control system open, with the result that the current to the
auto-cruise vacuum pump is interrupted, thus canceling the
constant-speed travel.
At the same time, moreover, the closing of the (NO) contacts
for the stop light results in the sending of the cancel signal to
the control unit, so that the auto-cruise vacuum pump current is
discontinued within the control unit, thereby canceling the
constant-speed travel.
The flow of current is from the sub fusible link
