< DISASSEMBLY AND ASSEMBLY >
CYLINDER BLOCK
 If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, hone or rebore the inner
wall.
 Oversize piston is provided. When using oversize piston, rebore
cylinder so that the clearance of the piston to cylinder bore satis-
fies the standard.
CAUTION:
When using oversize piston, use oversize pistons for all cylin-
ders with oversize piston rings.
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer (A).
Piston-to-Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bore inner diameter [direction (B), position (D)].
(Clearance) = (Cylinder bore inner diameter) – (Piston skirt diameter).
 If the calculated value exceeds the limit, replace piston and piston pin assembly. Refer to EM-129, "
Piston".
Reboring Cylinder Bore
1. Cylinder bore size is determined by adding piston to cylinder bore clearance to piston skirt diameter.
2. Install main bearing caps and main bearing beam, and tighten to the specified torque. Otherwise, cylinder
bores may be distorted in final assembly.
3. Cut cylinder bores.
NOTE:
 When any cylinder needs boring, all other cylinders must also be bored.
 Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so in diameter at a
time.
4. Hone cylinders to obtain the specified piston to cylinder bore clearance.
5. Measure finished cylinder bore for the out-of-round and taper.
NOTE:
Measurement should be done after cylinder bore cools down.
CRANKSHAFT MAIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft main journals with a micrometer. Oversize (O/S) : 0.2 mm (0.008 in)
SEM843E
Measure point
: Refer to EM-143, "CylinderBlock".
Standard
JPBIA0227ZZ
Standard and limit : Refer to EM-143, "CylinderBlock".
Rebored size calculation: D = A + B – C
where,
A: Piston skirt diameter as measured
B: Piston to cylinder bore clearance (standard value)
C: Honing allowance 0.02 mm (0.0008 in)
D: Bored diameter
Standard : Refer to EM-143, "
CylinderBlock".

System DescriptionINFOID:0000000003774357
OUTLINE
Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and
relay control function of IPDM E/R.
HEADLAMP (LO) OPERATION
 BCM detects the combination switch condition with the combination switch reading function.
 BCM transmits the low beam request signal to IPDM E/R with CAN communication according to the head-
lamp (LO) ON condition.
Headlamp (LO) ON condition- Lighting switch 2ND
- Lighting switch AUTO (auto light function ON judgment)
 IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low
beam request signal.
HEADLAMP (HI) OPERATION
 BCM transmits the high beam request signal to IPDM E/R and the combination meter with CAN communica-
tion according to the headlamp (HI) ON condition.
Headlamp (HI) ON condition- Lighting switch HI with the lighting switch 2ND or AUTO (auto light function ON judgment)
- Lighting switch PASS
 Combination meter turns the high beam indicator lamp ON according to the high beam request signal.
 IPDM E/R turns the integrated headlamp high relay ON, and turns the headlamp ON according to the high
beam request signal.
