CYLINDER BLOCK
• Install the main bearing cap while referring to the front mark
(B) and the journal number stamp (A).
NOTE:
Main bearing cap cannot be replaced as a single part,
because it is machined together with cylinder block.
8. Tighten main bearing cap bolts in numerical order as shown with the following steps:
a. Apply new engine oil to threads and seat surfaces of the bolts.
b. Tighten main bearing cap bolts in numerical order.
c. Turn main bearing cap bolts 60 degrees clockwise (angle tight- ening) in numerical order as shown.
CAUTION:
Check and confirm the tightening angle by using the Tool

• Check crankshaft end play. Refer to EM-102, "
Inspection".
9. Install piston to connecting rod with the following procedure:
a. Using a heat gun, heat the piston until the pist on pin can be pushed in by hand without excess force
[approximately 60 to 70 °C (140 to 158 °F)]. From the front to the rear, insert piston pin into piston and con-
necting rod.
b. Set so that the front mark (A) on the piston head and the cylin- der number (C) are in the position as shown.
NOTE:
The symbols without notes are for manufacturing.

EC-58
< SYSTEM DESCRIPTION >[HR16DE]
DIAGNOSIS SYSTEM (ECM)
• ECM blinks MIL for about 10 seconds if all SRT codes are not set.
MALFUNCTION WARNING MODE
Description
In this function ECM turns on or blinks MIL when it detects a malfunction in the emission control system com-
ponents and/or the powertrain control components (which affe
ct vehicle emissions) to inform the driver that a
malfunction has been detected.
Operation Procedure
1. Turn ignition switch ON.
2. Check that MIL illuminates. If it remains OFF, check MIL circuit. Refer to EC-456, "
Diagnosis Procedure".
3. Start engine and let it idle. • For two trip detection logic diagnoses, ECM turns on MIL when it detects the same malfunction twice inthe two consecutive driving cycles.
• For 1st trip detection logic diagnoses, ECM turns on MIL when it detects a malfunction in one driving cycle.
• ECM blinks MIL when it detects a malfunction t hat may damage the three way catalyst (misfire).
SELF-DIAGNOSTIC RESULTS MODE
Description
This function allows to indicate DTCs or 1st trip DT Cs stored in ECM according to the number of times MIL is
blinking.
How to Set Self-diagnostic Results Mode
NOTE:
• It is better to count the time accurately with a clock.
• It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a mal-
function.
• After ignition switch is turned off, ECM is always released from the “self-diagnostic results” mode.
1. Confirm that accelerator pedal is fully releas ed, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds. • Fully depress the accelerator pedal.
• Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it depressed for approx. 10 seconds until the MIL starts blinking.
NOTE:
Do not release the accelerator pedal for 10 seconds if MIL starts blinking during this period. This blinking
is displaying SRT status and is continued for another 10 seconds.
4. Fully release the accelerator pedal. ECM has entered to “Self-diagnostic results” mode.

INSPECTION AFTER REMOVAL
Check the following items, and replace the part if necessary.
• Check components for deformation, cracks, and other damage.
• Check boots of transverse link and steering outer so cket ball joint for breakage, axial end play, and swing
torque. Refer to FSU-10, "
Inspection" and FSU-20, "Ball Joint".
INSPECTION AFTER DISASSEMBLY
Wheel Hub
• Check wheel hub for cracks (with magnetic exploration or dye testing). Replace if necessary.
Steering Knuckle
• Check steering knuckle for deformation, cracks, and other damage. Replace if any non-standard conditions
are found.
Snap Rings
• Check snap ring for wear or cracks. Replace if necessary.
INSPECTION AFTER ASSEMBLY
Check wheel bearing rotating torque as per the following instructions.
NOTE:
The adequacy of turning torque can be judged from a measurement value by a spring balancer.
1. For a proper fit of the bearing, turn the wheel hub clockwise and counterclockwise, respectively, 10 times
or more with a press-fit load applied.
2. Set a suitable tool on strut mounting hole (upper). Measure rotating torque at an rpm of 8 - 12 rpm.
• If the turning torque cannot be obtained by the above method, measure the torque, according to the instructions below.
- Install drive shaft and tighten the hub lock nut to the specified
torque. Rotate the wheel hub to fit properly.
- Set a suitable tool on a wheel nut and measure turning torque at turning speeds of 8 to 12 rpm.
INSPECTION BEFORE INSTALLATION
Check wheel sensor rotor for foreign matter. Clean the rotor, if necessary.
INSPECTION AFTER INSTALLATION
1. Check wheel sensor harness to be sure the connectors are fully seated. Refer to BRC-140, "FRONT
WHEEL SENSOR : Removal and Installation".
2. Check the wheel alignment. Refer to FSU-7, "

Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2 ″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified oils.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe) . All hoses must be equipped with
positive shut-off devices (either manual or automatic) near the end of
the hoses opposite to the manifold gauge.
SERVICE COUPLERS
Do not attempt to connect HFC-134a (R-134a) service couplers to
the CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers
do not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. The hose fitting must be 1/
2 ″-16 ACME if the scale controls refrigerant flow electronically.
CHARGING CYLINDER
Using a charging cylinder is not re commended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.

5. Check that belt tension is within the specification using suitable tool. Refer to EM-116, "Drive Belt".
DRIVE BELT : InspectionINFOID:0000000012432250
• Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
• Visually check belt for wear, damage, and cracks on inside and edges.
• Turn crankshaft pulley clockwise twice, and check that the tension on all pulleys equalizes before testing.
• When measuring deflection, apply 98.1 N (10 kg, 22 lb) at the ( ) marked point.
• Measure the belt tension and frequency using suitable tool at the ( ) marked point.
CAUTION:
• When checking immediately after installation, first ad just it to the specified value. Then, after turning
crankshaft two turns or more, readjust to the speci fied value to avoid variation in deflection between
pulleys.
DRIVE BELT : AdjustmentINFOID:0000000012432251
CAUTION:
• When belt is replaced with new one, adjust belt tension to the value for “New belt,” because new belt will not fully seat in the pulley groove.
• When tension of the belt being used exceeds “Limit,” adjust it to the value for “After adjusted.”
• When installing a belt, check it is co rrectly engaged with the pulley groove.
• Do not allow engine oil or engine coolant to get on the belt.
• Do not twist or bend the belt strongly.
1. Partially remove the fender protector (RH) front side clip. Refer to EXT-38, "
Removal and Installation".
2. Loosen lock nut (A) and temporarily set to the following torque.
3. Adjust the belt tension by turning the adjusting bolt. Refer to EM-116, "
