CYLINDER BLOCK
 If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-130, "
ConnectingRodBearing".
Method of Using Plastigage
 Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting
rod bolts to the specified torque. Refer to EM-110, "
Disassembly and Assembly" for the tightening proce-
dure.
CAUTION:
Never rotate crankshaft.
 Remove connecting rod bearing cap and bearings, and using the
scale on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
 Install main bearings (3) to cylinder block (1) and main bearing
caps (2), and main bearing cap bolts with main bearing beam to
the specified torque. Refer to EM-110, "
Disassembly and Assem-
bly" for the tightening procedure.
 Measure the inner diameter of main bearing with a bore gauge.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)
 If the calculated value exceeds the limit, select proper main bear-
ing according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-132, "
MainBearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft journal and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install main bearing to cylinder block and main bearing caps, and tighten main bearing cap bolts with main
bearing beam to the specified torque. Refer to EM-110, "
Disassembly and Assembly" for the tightening pro-
cedure.
CAUTION:
Never rotate crankshaft.

EXHAUST SYSTEM
 Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
 When installing each mounting rubber, use silicon oil to avoid twisting.
 Temporarily tighten mounting nuts and bolts. Check each part for unusual interference, and then
tighten them to the specified torque.
 When installing each mounting rubber, avoid twisting or unusual extension in up/down, front/rear
and right/left directions.
InspectionINFOID:0000000003793263
INSPECTION AFTER INSTALLATION
 Check clearance between tail tube and rear bumper is even.
 With engine running, check exhaust tube joints for gas leakage and unusual noises.
 Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
 Oil pressure warning lamp
 Front wiper (LO, HI)
 Parking lamps
 License plate lamps
 Tail lamps
 Front fog lamps
 Headlamps (LO, HI)
 A/C compressor (magnet clutch)
 Cooling fan
Operation Procedure
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the
ignition switch OFF.
CAUTION:
Close passenger door.
4. Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test
starts.
5. The oil pressure warning lamp starts blinking when the auto active test starts.
6. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
 If auto active test mode cannot be actuated, check door switch system. Refer to DLK-57,
"ComponentFunctionCheck".
 Do not start the engine.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 5 steps are repeated 3 times.

IGNITION RELAY MALFUNCTION DETECTION FUNCTION
 IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
 IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
 If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop position by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop five times.

Cooling fan Turns ON the cooling fan relay-2 and the cooling fan relay-3 when ignition switch is
turned ON (Cooling fan operates at HI)
