SIGNAL WAVEFORM AND DATA

EC12B23B

Fig.1

Fig.2

Fig.1) This shows waveform of Crank Shaft Position Sensor and Cam Shaft Position Sensor simulatneously. The middle area
          indicates reference points of Crank Shaft Position Sensor and Cam Shaft Position Sensor. 

Fig.2) Crank Shaft Position Sensor and Cam Shaft Position Sensor signal are measured simultaneously.  
          Cam Shaft Position Sensor 
          signal is outputted once when Crank Shaft Position sensor signal is outputted twice. LOW and HIGH output of Cam Shaft 
          Position sensor reference point is detected at Crank Shaft Position sensor reference point.
          ( Injection sequence is determined based on LOW and HIGH signal of Cam Shaft Position Sensor reference point as 
            detecting cylinder position.)

1.

ECM recognizes HIGH signal as LOW signal when CMPS signal drops below 2.0V and LOW signal as HIGH signal
when CMPS signal rises above 3.8V.

2.

V0 - the Minimum voltage of LOW signal does not drop below 0.0V due to the hall sensor inside resistance. When
the Minimum voltage of LOW signal is above 0.6V during signal waveform inspection, check excessive resistance
inside of CMPS component or in ground circuit.

MONITOR SCANTOOL DATA

EB35BB16

1.

Connect Scantool to Data Link Connector (DLC).

2.

Warm engine up to normal operating temperature.

3.

Turn "OFF" electrical devices and A/C.

FUEL SYSTEM

4.

Monitor "ENGINE SPEED SENSOR" parameter on the Scantool.

Specification : 750±50RPM at idle

Fig.1) Check "ENGINE SPEED SENSOR" parameter carefully after warming engine up, also check engine stall and rpm instability 
          or engine shut down.

TERMINAL AND CONNECTOR INSPECTION

E9A94F7B

1.

Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various prob-
lems and damge of component.

2.

Perform checking procedure as follows.

1)

Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.

2)

Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking
device and connecting condition between terminal and wiring.

NOTE

Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for
checking connecting condition. ( after checking, reconnect the pin at correct position. )

3.

Is the problem found?

YES

▶

Repair the trouble causing part and go to "Verification of Vehicle Repair".

NO

▶

Go to "Power Circuit Inspection".

POWER CIRCUIT INSPECTION

1.

IG KEY "OFF", ENGINE "OFF".

2.

Disconnect CMPS connector.

3.

IG KEY "ON".

DTC TROUBLESHOOTING PROCEDURES

FL -273

4.

Measure the voltage of CMPS connector terminal 1.

Specification : 11.0V~13.0V ( Main relay "ON" power )

5.

Is the measured voltage within the specification?

YES

▶

Go to "Signal Circuit Inspection".

NO

▶

Repair open in Main relay power circuit and fuse, and go to "Verification of Vehicle Repair".

[Check open in E/R FUSE

＆

RELAY BOX 15A SENSOR #2 FUSE and related circuit.]

※

If the fuse is damaged again after replacing the damaged fuse, repair short to ground in Main relay power circuit.

SIGNAL CIRCUIT INSPECTION

1.

Check CMPS signal voltage

1)

IG KEY "OFF", ENGINE "OFF".

2)

Disconnect CMPS connector.

3)

IG KEY "ON".

4)

Measure the voltage of CMPS connector terminal 2.

Specification : 4.8V~5.1V

5)

Is the measured voltage within the specification?

YES

▶

Go to "Ground Circuit Inspection".

NO

▶

Go to "Check open in signal circuit" as follows.

2.

Check open in signal circuit

1)

IG KEY "OFF", ENGINE "OFF".

2)

Disconnect CMPS connector and ECM connector.

3)

Check continuity between CMPS connector terminal 2 and ECM connector (C230-A) terminal 50.

Specification : continuity ( below 1.0

Ω

)

4)

Is the measured resistance within the specification? (Is continuity confirmed?)
