Description
INFOID:0000000006496268
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Diagnosis Procedure
INFOID:0000000006635698
1.
CHECK OIL PRESSURE WARNING LAMP
1.
Start engine.
2.
Check oil pressure warning lamp and confirm it is not illumi-
nated.
Is oil pressure warning lamp illuminated?
YES
>> Check the engine oil level. Refer to
NO
>> GO TO 2.
2.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE
Check the exhaust valve timing control solenoid valve. Refer to
EC-576, "Component Inspection"
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Replace exhaust valve timing control solenoid valve. Refer to
.
3.
CHECK CRANKSHAFT POSITION SENSOR
Check the crankshaft position sensor. Refer to
EC-658, "Component Inspection"
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Replace crankshaft position sensor. Refer to
4.
CHECK EXHAUST CAMSHAFT POSITION SENSOR
Check the exhaust camshaft position sensor. Refer to
EC-662, "Component Inspection"
.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Replace exhaust valve timing control position sensor. Refer to
5.
CHECK CAMSHAFT (EXHAUST)
Check the following.
ENG SPEED
1,700 - 2,950 rpm (A constant rotation is maintained.)
COOLAN TEMP/S
More than 70
°
C (158
°
F)
Selector lever
1st or 2nd position
Driving location uphill
Driving vehicle uphill
(Increased engine load will help maintain the driving
conditions required for this test.)

• Accumulation of debris to the signal plate of camshaft rear end
• Chipping signal plate of camshaft rear end
Is the inspection result normal?
YES
>> GO TO 6.
NO
>> Remove debris and clean the signal plate of camshaft
rear end or replace camshaft. Refer to
.
6.
CHECK TIMING CHAIN INSTALLATION
Check service records for any recent repairs that may cause timing chain misaligned.
Are there any service records that may cause timing chain misaligned?
YES
>> Check timing chain installation. Refer to
NO
>> GO TO 7.
7.
CHECK LUBRICATION CIRCUIT
, “INSPECTION AFTER INSTALLATION”.
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-42, "Intermittent Incident"
.
NO
>> Clean lubrication line.
Component Inspection
INFOID:0000000006635699
1.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-I
1.
Turn ignition switch OFF.
2.
Disconnect exhaust valve timing control solenoid valve harness connector.
3.
Check resistance between exhaust valve timing control solenoid valve terminals as per the following.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Replace exhaust valve timing control solenoid valve. Refer to
.
2.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II
1.
Remove exhaust valve timing control solenoid valve.
2.
Provide 12 V DC between exhaust valve timing control solenoid
valve terminals 1 and 2, and then interrupt it. Check that the
plunger moves as shown in the figure.
CAUTION:
Do not apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in exhaust valve
timing control solenoid valve.
NOTE:
Always replace O-ring when exhaust valve timing control
solenoid valve is removed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Replace exhaust valve timing control solenoid valve. Refer to
.
