(c) Using SST and a hammer, drive in a new pilot bearing.
SST 09301-001 10
(d) Install 2 new bolts.
(e) First, torque the 2 bolts uniformly a little at a time.
Torque: 49 N´m (500 kgf´cm, 36 ft´lbf)
(f) Then tighten the 2 bolts an additional 80 - 100°.
6. INSPECT DIAPHRAGM SPRING FOR WEAR
Using calipers, measure the diaphragm spring for depth and
width of wear.
Maximum:
Depth A: 0.6 mm (0.024 in.)
Width B: 5.0 mm (0.197 in.)
If necessary, replace the clutch cover.
7. INSPECT RELEASE BEARING
Turn the bearing by hand while applying force in the axial direc-
tion.
HINT:
The bearing is permanently lubricated and requires no cleaning
or lubrication.
If a problem is found, replace the bearing together with the hub.

The 2 trip repeats the same mode a 2nd time. (However,
the IG switch must be turned OFF between the 1st trip and
2nd trip).
Freeze frame data:
Freeze frame data records the engine condition when a
misfire (DTC P0300 - P0306) or fuel trim malfunction
(DTC P0171, P0172), or other malfunction (first malfunc-
tion only), is detected.
Because freeze frame data records the engine conditions
(fuel system, calculator load, engine coolant tempera-
ture, fuel trim, engine speed, vehicle speed, etc.) when
the malfunction is detected, when troubleshooting it is
useful for determining whether the vehicle was running or
stopped, the engine warmed up or not, the air-fuel ratio
lean or rich, etc. at the time of the malfunction.
Priorities for Troubleshooting:
If troubleshooting priorities for multiple DTC are given in
the applicable diagnostic chart, these should be followed.
If no instructions are given troubleshoot DTC according
to the following priorities.
(1) DTC other than fuel trim malfunction (DTC P0171,
P0172), EGR (DTC P0401, P0402), and misfire
(DTC P0300 - 0306).
(2) Fuel trim malfunction (DTC P0171, P0172) and
EGR (DTC P0401, P0402).
(3) Misfire (DTC P0300 - P0306).
(b) Check the DLC3.
The vehicle's ECM uses V.P.W. (Variable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.
Terminal No.Connection / Voltage or ResistanceCondition
2Bus  Line / Pulse generationDuring transmission
4Chassis Ground / e Body Ground 1 W or lessAlways
5Signal Ground / e Body Ground 1 W or lessAlways
16Battery Positive / e Body Ground 9 - 14 VAlways
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the OBD II scan tool or
TOYOTA hand-held tester to DLC3, turned the ignition switch
ON and operated the scan tool, there is a problem on the ve-
hicle side or tool side.

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

If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.

DTC P1300 Igniter Circuit Malfunction
CIRCUIT DESCRIPTION
The ECM determines the ignition timing, turns on Tr1 at a predetermined angle (°CA) before the desired
ignition timing and outputs an ignition signal (IGT) º1º to the igniter.
Since the width of the IGT signal is constant, the dwell angle control circuit in the igniter determines the time
the control circuit starts primary current flow to the ignition coil based on the engine rpm and ignition timing
one revolution ago, that is, the time the Tr2 turns on.
When it reaches the ignition timing, the ECM turns Tr1 off and outputs the IGT signal º0º.
This turns Tr2 off, interrupting the primary current flow and generating a high voltage in the secondary coil
which causes the spark plug to spark. Also, by the counter electromotive force generated when the primary
current is interrupted, the igniter sends an ignition confirmation signal (IGF) to the ECM.
The ECM stops fuel injection as a fail safe function when the IGF signal is not input to the ECM.
DTC No.DTC Detecting ConditionTrouble Area
P1300No IGF signal to ECM for 6 consecutive IGT signals during
engine running

(d) Check the valve overall length.
Standard overall length:
Intake 98.29 - 98.79 mm (3.8697 - 3.8894 in.)
Exhaust 98.84 - 99.34 mm (3.8913 - 3.9110 in.)
Minimum overall length:
Intake 98.19 mm (3.8657 in.)
Exhaust 98.74 mm (3.8874 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder or
replace the valve.
NOTICE:
Do not grind off more than the minimum overall length.
11. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a thin coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate the valve.
(c) Check the valve face and seat for the following:

If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.

If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.

Check that the seat contact is in the middle of the
valve face with the following width:
Intake 1.0 - 1.4 mm (0.039 - 0.055 in.)
Exhaust 1.2 - 1.6 mm (0.047 - 0.063 in.)
If not, correct the valve seats as follows:

If the seating is too high on the valve face, use 15°
and 45° cutters to correct the seat.

If the seating is too low on the valve face, use 75°
and 45° cutters to correct the seat.
(d) Hand-lap the valve and valve seat with an abrasive com-
pound.
(e) After hand-lapping, clean the valve and valve seat.
12. INSPECT VALVE SPRINGS
(a) Using a steel square, measure the deviation of the valve
spring.
Maximum deviation: 2.0 mm (0.079 in.)
If deviation is greater than maximum, replace the valve spring.
(b) Using vernier calipers, measure the free length of the
valve spring.
Free length: 41.70 mm (1.6417 in.)
If the free length is not as specified, replace the valve spring.
(c) Using a spring tester, measure the tension of the valve
spring at the specified installed length.
Installed tension:
186 - 206 N (19.0 - 21.0 kgf, 42 - 46 lbf)
at 34.5 mm (1.358 in.)
If the installed tension is not as specified, replace the valve
spring.

in the illustration.
Adhesive:
Part No. 08833-00070, THREE BOND 1324
or equivalent
(b) Using a wooden block and hammer, tap in a new heater
union, leaving standard position protruding from the cylin-
der head.
Standard protrusion:
48 mm (1.89 in.)
NOTICE:
Do not tap it in too far.
2. INSTALL VALVES
(a) Install a new oil seal on the valve guide bushing.
(b) Install these parts:
(1) Valve
(2) Spring seat
(3) Valve spring

(c) Position the piston rings so that the ring ends are as
shown.
NOTICE:
Do not align the piston ring ends.
3. INSTALL BEARINGS
(a) Align the bearing claw with the groove of the connecting
rod and connecting cap.
(b) Install the bearings in the connecting rod and connecting
rod cap.
NOTICE:
Apply a generous amount of oil on the sliding surface of the
bearing, and not on the back of it or on the surface to which
it is installed.
