and its component parts are explained.

Diagnostic Trouble Code No. and Detection Item
Indicates the diagnostic trouble codes, diagnostic
trouble code settings and suspect areas for a
problem.
Wiring Diagram
This shows a wiring diagram of the circuit.
Use this diagram together with ELECTRICAL
WIRING DIAGRAM to thoroughly understand the
circuit.
Wire colors are indicated by an alphabetical code.

Y = Yellow, SB = Sky Blue
The first letter indicates the basic wire color and
the second letter indicates the color of the stripe.
Inspection Procedures
Use the inspection procedures to determine
if the circuit is normal or abnormal. If it is ab-
normal, use it to determine whether the prob-
lem is located in the sensors, actuators, wire
harness or ECU.

Indicates the condition of the connector of the ECU
during the check.


Connections of tester are
indicated by (+), (±) after
terminals name.

15. INSPECT INTAKE VALVE
(a) Using a vernier calipers, check the valve overall length.
Standard overall length: 88.65 mm (3.4902 in.)
Minimum overall length: 88.35 mm (3.4784 in.)
(b) Using a vernier calipers, check the valve head margin thickness.
Standard margin thickness: 1.0 mm (0.039 in.)
Minimum margin thickness: 0.7 mm (0.028 in.)
16. INSPECT EXHAUST VALVE
(a) Using a vernier calipers, check the valve overall length. Standard overall length: 88.69 mm (3.4917 in.)
Minimum overall length: 88.39 mm (3.4799 in.)
(b) Using a vernier calipers, check the valve head margin thickness.
Standard margin thickness: 1.0 mm (0.039 in.)
Minimum margin thickness: 0.7 mm (0.028 in.)
17. INSPECT VALVE SEATS
(a) Apply a light coat of prussian blue (or white lead) to the valve face.
(b) Lightly press the valve against the seat.
(c) Check the valve face and seat according to the following procedure.
(1) If blue appears 360 around the face, the valve is
concentric. If not, replace the valve.

(2) If blue appears 360
around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
(3) Check that the seat contact is in the middle of the valve face with the width between 1.0 ± 1.4 mm
(0.039 ± 0.055 in.).
18. REPAIR VALVE SEATS
NOTICE:
Take off a cutter gradually to make smooth valve seats.
(a) If the seating is too high on the valve face, use 30
and
45
cutters to correct the seat.
(b) If the seating is too low on the valve face, use 75
and 45

cutters to correct the seat.
(c) Hand±lap the valve and valve seat with an abrasive com- pound.
(d) Check the valve seating position.
19. INSPECT VALVE LIFTER
(a) Using a micrometer, measure the lifter diameter. Lifter diameter:
30.966 ± 30.976 mm (1.2191 ±1.2195 in.)
20. INSPECT VALVE LIFTER OIL CLEARANCE
(a) Using a caliper gauge, measure the lifter bore diameter of the cylinder head.
Lifter bore diameter:
31.000 ± 31.025 mm (1.2205 ± 1.2215 in.)
(b) Subtract the lifter diameter measurement from the lifter bore diameter measurement.
Standard oil clearance:
0.024 ± 0.059 mm (0.0009 ± 0.0023 in.)
Maximum oil clearance: 0.1 mm (0.0039 in.)

1. CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte quantity of each cell.
(1) If the electrolyte is under the low level, replace the battery (or add di\
stilled water if possible) andcheck the charging system.
2. CHECK BATTERY VOLTAGE
(a) If it has not been 20 minutes since you drove the vehicleor since the engine was stopped, turn the ignition switch
and the electrical system (headlight, blower motor, rear
defogger etc.) to the on position for 60 seconds. This will
remove the surface charge on the battery.
(b) Turn off the ignition switch and the electrical systems.
(c) Measure the battery voltage between the negative (±) and positive (+) terminals of the battery.
Standard voltage: 12.5 to 12.9 V at 20 C (68 F)
HINT:
If the voltage is less than specification, charge the battery.
(d) Check the indicator as shown in the illustration.

3. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loosened or corroded.
(b) Check the fusible links, high±current fuses and regular fuses.
4. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cordsetc.
HINT:

If any defect found, replace the drive belt.

Cracks on the rib side of a belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be
replaced.
