MONITOR RESULT
The detailed information is described in CHECKING MONITOR STATUSº (see page DI-3).
TID (Test Identification) is assigned to each emission-related component.
TLT (Test Limit Type):
If TLT is 0, the component is malfunctioning when the test value is higher than the test limit.
If TLT is 1, the component is malfunctioning when the test value is lower than the test limit.
CID (Component Identification) is assigned to each test value.
Unit Conversion is used to calculate the test value indicated on generic OBD scan tools.

INSPECTION PROCEDURE
In case of using TOYOTA hand-held tester, start inspection from step 1.
In case of not using TOYOTA hand-held tester, start inspection from step 2.
1 Check telescopic motor operation using TOYOTA hand-held tester.
PREPARATION:
(a) Connect the TOYOTA hand-held tester to the DLC3.
(b) Turn ignition switch ON and push the TOYOTA hand-held
tester main switch ON.
(c) Select the ACTIVE TEST mode on the TOYOTA hand-
held tester.
CHECK:
Check that the steering column length become short (long) and
confirm that telescopic position value change when the AC-
TIVE TEST carried out.
OK:
Steering column length must be short (long).
Telescopic position value must be changed.
OK Proceed to next circuit inspection shown on the
problem symptoms table (See page DI-663).
NG
2 Check telescopic motor.
PREPARATION:
(a) Disconnect telescopic motor connector and tilt motor con-
nector.
(b) Remove telescopic motor (See page SR-30).
CHECK:

(c) Check the valve head margin thickness.
Standard margin thickness:
IN 1.25 mm (0.049 in.)
EX 1.40 mm (0.055 in.)
Minimum margin thickness:
0.5 mm (0.020 in.)
If the margin thickness is less than the minimum, replace the
valve.
(d) Check the valve overall length.
Standard overall length:
Intake: 95.05 mm (3.7421 in.)
Exhaust: 95.10 mm (3.7441 in.)
Minimum overall length:
Intake: 94.55 mm (3.7224 in.)
Exhaust: 94.60 mm (3.7244 in.)
If the overall length is less than the 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 to below the minimum.
11. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats. Re-
move just enough metal to clean the seats.

(b) Using vernier calipers, measure the free length of the
valve spring.
Free length:
54.1 mm (2.130 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 installed length.
Installed tension:
204 - 226 N (20.8 - 23.0 kgf, 45.9 - 50.7 lbf)
at 35.0 mm (1.378 in.)
If the installed tension is not as specified, replace the valve
spring.
13. INSPECT CAMSHAFT FOR RUNOUT
(a) Place the camshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout:
0.08 mm (0.0031 in.)
If the circle runout is greater than the maximum, replace the
camshaft.
14. INSPECT CAM LOBES
Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
Intake:
41.94 - 42.04 mm (1.6512 - 1.6551 in.)
Exhaust:
41.96 - 42.06 mm (1.6520 - 1.6559 in.)
Minimum cam lobe height:
Intake:
41.79 mm (1.6453 in.)
Exhaust:
41.81 mm (1.6461 in.)
If the cam lobe height is less than the minimum, replace the
camshaft.

(A), (B) and (C).
(10) Install the oil feed pipe and the 22 bearing cap bolts
as shown.
HINT:
Bolt length:
94 mm (3.70 in.) for A
72 mm (2.83 in.) for B

(a) Check the crankshaft pulley position.
Check that the timing mark of the crankshaft pulley is
aligned with the centers of the crankshaft pulley bolt and
the idler pulley bolt.
NOTICE:
Having the crankshaft pulley at the wrong angle can cause
the piston head and the valve head to come into contact
with each other when removing the camshaft, causing
damage on them. So always set the crankshaft pulley at the
correct angle.
(b) Remove the RH camshafts.
(1) Move a service bolt of the sub-gear upward by turn-
ing the hexagon shaped port of the exhaust cam-
shaft with a wrench.
(2) Secure the sub-gear to the main gear with a service
bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 - 20 mm
HINT:
When removing the camshafts, make sure that the torsional
spring force of the sub-gear is eliminated by the above opera-
tion.
(3) Set the timing mark (1 dot mark) of the camshaft
main gear at approx. 10° angle by turning the hexa-
gon wrench head portion of the exhaust camshaft
with a wrench.
(4) Uniformly loosen and remove the 22 bearing cap
bolts a little at a time for several times in the se-
quence shown.
