< FUNCTION DIAGNOSIS >[BASE AUDIO AND DISPLAY SYSTEM]
DIAGNOSIS SYSTEM (AV CONTROL UNIT)
 Displays the communication status between AV control unit (mas-
ter unit) and each unit.
 The error counter displays “OK” if any malfunction was not
detected in the past and displays “0” if a malfunction is detected. It
increases by 1 if the condition is normal at the next ignition switch
ON cycle. The upper limit of the counter is 39.
 If it resets, the error counter is erased.
Delete Unit Connection Log
Deletes any unit connection records and error records from the AV
control unit memory. (Clear the records of the unit that has been
removed)

SEATS
When isolating seat noise it is important to note the position the seat is in and the load placed on the seat
when the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

7.CHECK SPARK PLUG
Check the initial spark plug for fouling, etc.
Is the inspection result normal?
YES >> Replace spark plug(s) with standard type one(s). For
spark plug type, refer to EM-136, "
Spark Plug".
NO >> Repair or clean spark plug. Then GO TO 8.
8.CHECK FUNCTION OF IGNITION COIL-III
1. Reconnect the initial spark plugs.
2. Crank engine for about 3 seconds, and recheck whether spark is generated between the spark plug and
the grounded portion.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace spark plug(s) with standard type one(s). For spark plug type, refer to EM-136, "
Spark
Plug".
9.CHECK COMPRESSION PRESSURE
Check compression pressure. Refer to EM-22, "
Inspection".
Is the inspection result normal?
YES >> GO TO 10.
NO >> Check pistons, piston rings, valves, valve seats and cylinder head gaskets.
10.CHECK FUEL PRESSURE
1. Install all removed parts.
2. Release fuel pressure to zero. Refer to EC-411, "
Inspection".
3. Install fuel pressure gauge and check fuel pressure. Refer to EC-411, "
Inspection".
Is the inspection result normal?
YES >> GO TO 12.
NO >> GO TO 11.
11 .DETECT MALFUNCTIONING PART
Check fuel hoses and fuel tubes for clogging.
Is the inspection result normal?
YES >> Replace “fuel filter and fuel pump assembly”.
NO >> Repair or replace malfunctioning part.
12.CHECK IGNITION TIMING
Check idle speed and ignition timing.
For procedure, refer to EC-11, "
BASIC INSPECTION : Special Repair Requirement".
For specification, refer to EC-414, "
Idle Speed" and EC-414, "Ignition Timing".
Is the inspection result normal?
YES >> GO TO 13.
NO >> Follow the EC-11, "
BASIC INSPECTION : Special Repair Requirement".
13.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT
1. Turn ignition switch OFF.

d. Using the valve guide reamer (commercial service tool) (A),
apply reamer finish to valve guide.
2. If valve seat is removed in step 7 (DISASSEMBLY), install it.
Replace with oversize [0.5 mm (0.020 in)] valve seat.
a. Ream cylinder head recess diameter (a) for service valve seat.
 Be sure to ream in circles concentric to valve guide center.
This will enable valve to fit correctly.
b. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil (A).
c. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head.
WARNING:
Cylinder head contains heat. When working, wear protective equipment to avoid getting burned.
CAUTION:
Avoid directly touching cold valve seats.
d. Using the valve seat cutter set (commercial service tool) or valve
seat grinder, finish seat to the specified dimensions. Refer to
EM-139, "
CylinderHead".
CAUTION:
When using the valve seat cutter, firmly grip cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cut in a single drive. Improper
pressure on with cutter or cutting many different times may
result in stage valve seat.
e. Using compound, grind to adjust valve fitting.
f. Check again for normal contact. Refer to EM-104, "
Inspection".
3. Install new valve oil seals as follows:Standard

13. Install connecting rod bearing cap.
 Match the stamped cylinder number marks on connecting rod
with those on connecting rod bearing cap to install.
 Be sure that front mark (H) on connecting rod bearing cap is facing front of the engine.
14. Tighten connecting rod bolt as follows:
a. Inspect the outer diameter of connecting rod bolt. Refer to EM-119, "
Inspection".
b. Apply engine oil to the threads and seats of connecting rod bolts.
c. Tighten connecting rod bolts.
d. Then tighten all connecting rod bolts 90 degrees clockwise (angle tightening).
CAUTION:
Always use the angle wrench [SST: KV10112100 (BT8653-
A)]. Avoid tightening based on visual check alone.
 After tightening connecting rod bolts, check that crankshaft
rotates smoothly.
 Check the connecting rod side clearance. Refer to EM-119,
"Inspection".
15. Install baffle plate to main bearing beam.
16. Install new rear oil seal retainer to cylinder block. Refer to EM-94, "
REAR OIL SEAL : Removal and Instal-
lation".
17. Install pilot converter.
