``LOCK MODE'' displayed on CONSULT screen
Con®rm SELF-DIAGNOSTIC RESULTS
``LOCK MODE'' is displayed on CONSULT
screen.
1. Turn the ignition switch to OFF position
and wait 1 minute.
(After 1 minute, security indicator will
blink.)
2. Turn the ignition key switch to ON posi-
tion with a registered key.
(Do not start engine.) Wait 5 seconds.
3. Return the key to the OFF position.
4. Repeat steps 2 and 3 twice (total of
three cycles).
5. Start the engine.
Does the engine start?
No
cYe s
System is OK.
(Now the system is
escaped from ``LOCK
MODE''.)
PERFORM INITIALISATION.
Perform initialisation with CONSULT.
For the initialisation procedure, refer to
``CONSULT operation manual NATS V2.0
(GASOLINE)''.
Can the system be initialised?
Note: If the initialisation is incompleted or
failed, CONSULT shows
mes-
sage on the screen.
No
cYe s
System is OK.
Go to DIAGNOSTIC PROCEDURE 5,
EL-265 to check ``CHAIN OF IMMU-KEY''.

CAMSHAFT VISUAL CHECK
Check camshaft for scratches, seizure and wear.
CAMSHAFT END PLAY
1. Install camshaft in cylinder head.
2. Measure camshaft end play.
Camshaft end play:
0.065 - 0.169 mm (0.0026 - 0.0067 in)
CAMSHAFT JOURNAL CLEARANCE
1. Measure the inner diameter of camshaft bearing.
Standard inner diameter:
30.000 - 30.021 mm (1.1811 - 1.1819 in)
2. Measure the outer diameter of camshaft journal.
Standard outer diameter:
29.935 - 29.955 mm (1.1785 - 1.1793 in)
If the clearance is greater than the maximum, replace camshaft
and/or cylinder head.
Maximum clearance:
0.045 - 0.086 mm (0.0018 - 0.0034 in)
CAMSHAFT RUNOUT
Camshaft runout [TIR (Total Indicator Reading)]:
Limit 0.02 mm (0.0008 in)
If beyond the limit, replace.
CAMSHAFT CAM HEIGHT
Standard cam height:
Intake
48.005 - 48.195 mm (1.8900 - 1.8974 in)
Exhaust
49.505 - 49.695 mm (1.9490 - 1.9565 in)
Cam wear:
Limit 0.15 mm (0.0059 in)

CRANKSHAFT
1. Check crankshaft main and pin journals for score, wear or
cracks.
2. With a micrometer, measure journals for taper and out-of-
round.
Out-of-round (X þ Y):
Main journal
Less than 0.005 mm (0.0002 in)
Pin journal
Less than 0.0025 mm (0.0001 in)
Taper (A þ B):
Main journal
Less than 0.005 mm (0.0002 in)
Pin journal
Less than 0.0025 mm (0.0001 in)
3. Measure crankshaft runout.
Runout (Total indicator reading):
Standard Less than 0.025 mm (0.0010 in)
Limit 0.05 mm (0.0020 in)
BEARING CLEARANCE
+Use Method A or Method B. Method A is preferred because it
is more accurate.
Method A (Using bore gauge and micrometer)
Main bearing
1. Set main bearings in their proper positions on cylinder block
and main bearing cap.
2. Install main bearing cap to cylinder block.
Tighten all bolts in correct order in two or three stages. Refer
to EM-54.
3. Measure inner diameter ``A'' of each main bearing.

4. Measure outer diameter ``Dp'' of each crankshaft pin journal.
5. Calculate connecting rod bearing clearance.
Connecting rod bearing clearance=CþDp:
Standard
0.014 - 0.054 mm (0.0006 - 0.0021 in)
Limit
0.090 mm (0.0035 in)
If it exceeds the limit, replace bearing.
+If it still exceeds the limit even with a new bearing, regrind crank
pin and use undersized bearings.
+Refer to SDS for regrinding crankshaft and available ser-
vice parts.
Method B (Using plastigage)
CAUTION:
+Do not turn crankshaft or connecting rod while plastigage
is being inserted.
+If incorrect bearing clearance exists, use a thicker or
undersized main bearing to ensure speci®ed clearance.
CONNECTING ROD BUSHING CLEARANCE (Small end)
1. Measure inner diameter ``C'' of bushing.
2. Measure outer diameter ``Dp'' of piston pin.
3. Calculate connecting rod bushing clearance.
Connecting rod bushing clearance=CþDp
Standard:
0.025 - 0.044 mm (0.0010 - 0.0017 in)
If it exceeds the limit, replace connecting rod assembly or con-
necting rod bushing and/or piston set with pin.
REPLACEMENT OF CONNECTING ROD BUSHING
(Small end)
1. Drive in small end bushing until it is ¯ush with end surface of
rod.
Be sure to align the oil holes.
2. Ream the bushing so that clearance with piston pin is within
speci®cation.
Clearance between connecting rod bushing and pis-
ton pin:
0.005 - 0.017 mm (0.0002 - 0.0007 in)
FLYWHEEL/DRIVE PLATE RUNOUT
Runout (Total indicator reading):
Less than 0.15 mm (0.0059 in)
CAUTION:
+Be careful not to damage the ring gear teeth.
+Check the drive plate for deformation or cracks.
+Do not allow any magnetic materials to contact the ring
gear teeth.
+Do not resurface drive plate. Replace as necessary.
