DTC DETECTION LOGIC
NOTE:
• If DTC P1217 is displayed with DTC UXXXX, first perform the tr ouble diagnosis for DTC UXXXX.
• If DTC P1217 is displayed with DTC P0607, first pe rform the trouble diagnosis for DTC P0607. Refer
to EC-884, "DTC Logic"
.
If the cooling fan or another component in the coo ling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be su re to replace the coolant. Refer to CO-35, "System Inspection"
.
Also, replace the engine oil. Refer to MA-27, "ENGINE OIL : Changing Engine Oil"
.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-12, "FOR USA AND CANADA : Engine Cool-
ant Mixture Ratio".
2. After refilling coolant, run engine to en sure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-892, "Component Function Check"
.
NOTE:
Use component function check to check the overall functi on of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-893, "Diagnosis Procedure"
.
Component Function CheckINFOID:0000000009462750
1.PERFORM COMPONENT FUNCTION CHECK-I
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.

IGNITION SIGNAL
Is the inspection result normal?
YES >> Check intermittent incident. Refer to
GI-43, "Intermittent Incident".
NO >> Replace malfunctioning ignition coil with power transistor. Refer to EM-162, "Removal and Instal-
lation LH" or EM-162, "Removal and Installation RH".
Component Inspection (Igniti on Coil with Power Transistor)INFOID:0000000009462850
1.CHECK IGNITION COIL WITH POWER TRANSISTOR-I
1. Turn ignition switch OFF.
2. Disconnect ignition coil harness connector.
3. Check resistance between ignition coil terminals as per the following.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace malfunctioning ignition coil with power transistor. Refer to EM-162, "Removal and Instal-
lation LH" or EM-162, "Removal and Installation RH".
2.CHECK IGNITION COIL WITH POWER TRANSISTOR-II
CAUTION:
Perform the following procedure in a place with no combustible objects and good ventilation.
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT to release fuel pressure, or fuel pressure applies again during the following proce-
dure.
4. Start engine.
5. After engine stalls, crank it 2 or 3 times to release all fuel pressure.
6. Turn ignition switch OFF.
7. Remove all ignition coil harness connectors to avoi d the electrical discharge from the ignition coils.
8. Remove ignition coil and spark plug of the cylinder to be checked.
9. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
10. Connect spark plug and harness connector to ignition coil.
11. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 - 0.66 in) between the edge of the spark plug and grounded metal
portion as shown in the figure.
12. Crank engine for approximately 3 seconds, and check whether spark is generated between the spark plug and the grounded
metal portion.
CAUTION:
• During the operation, always stay 0.5 m (19.7 in) or more
away from the spark plug and the ignition coil. Be careful
not to get an electrical s hock while checking, because the
electrical discharge voltage becomes 20 kV or more.
• It might cause to damage the igni tion coil if the gap of more than 17 mm (0.66 in) is taken.
NOTE:
When the gap is less than 13 mm (0.52 in), the sp ark might be generated even if the coil is mal-
functioning.
Is the inspection result normal?
YES >> INSPECTION END

SENSOR POWER SUPPLY2 CIRCUIT
DescriptionINFOID:0000000009462861
ECM supplies a voltage of 5 V to some of the sensors systematically divided into 2 groups, respectively.
Accordingly, when a short circuit develops in a sensor power source, a malfunction may occur simultaneously
in the sensors belonging to the same group as the short-circuited sensor.
Sensor power supply 1
• Accelerator pedal position (APP) sensor 1
• Camshaft position (CMP) sensor (PHASE)
• Electric throttle control actuator
• Battery current sensor
NOTE:
If sensor power supply 1 circuit is malfunctioning, DTC P0643 is displayed.
Sensor power supply 2
• Accelerator pedal position (APP) sensor 2
• Crankshaft position (CKP) sensor (POS)
• Refrigerant pressure sensor
• EVAP control system pressure sensor
• Engine oil pressure sensor
Diagnosis ProcedureINFOID:0000000009462862
1.CHECK SENSOR POWER SUPPLY 1
1. Turn ignition switch OFF.
2. Disconnect ECM harness connectors
3. Turn ignition switch ON.
4. Check the voltage between ECM harness connector and ground.
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-43, "Intermittent Incident".
NO >> GO TO 2.
2.CHECK SENSOR POWER SUPPLY 2 CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect following sensors harness connector.
3. Check harness for short to power and short to ground, between the following terminals.
