SKYACTIV-G 1.3, SKYACTIV-G 1.5 (PCM 200 Pin Type)

1.  Install the manifold gauge. (See REFRIGERANT SYSTEM GENERAL PROCEDURES.)

2.  Verify the high-pressure side reading of the manifold gauge.

3.  Measure the terminal voltage at PCM terminal 2BB, 2AX and 2AJ.

4.  Using the graph below, measure and verify the terminal voltages at 2AX.

5.  Follow the PCM inspection when measuring the other terminal voltages. (See PCM INSPECTION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

•  Terminal 2BB: Approx. 5 V (Ignition switch ON)

•  Terminal 2AJ: 1.0 V or less

―  If each voltage is not normal, inspect the related wiring harness.

•  If there is any malfunction, replace the related wiring harness.

•  If the wiring harness is normal, replace the refrigerant pressure sensor. (See REFRIGERANT PRESSURE SENSOR REMOVAL/INSTALLATION [MANUAL AIR CONDITIONER].)

SKYACTIV-G 1.5 (PCM 186 Pin Type)

1.  Install the manifold gauge. (See REFRIGERANT SYSTEM GENERAL PROCEDURES.)

2.  Verify the high-pressure side reading of the manifold gauge.

3.  Measure the terminal voltage at PCM terminal 2AZ, 2AV and 2AI.

4.  Using the graph below, measure and verify the terminal voltages at 2AV.

5.  Follow the PCM inspection when measuring the other terminal voltages. (See PCM INSPECTION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

•  Terminal 2AZ: Approx. 5 V (Ignition switch ON)

•  Terminal 2AI: 1.0 V or less

―  If each voltage is not normal, inspect the related wiring harness.

•  If there is any malfunction, replace the related wiring harness.

•  If the wiring harness is normal, replace the refrigerant pressure sensor. (See REFRIGERANT PRESSURE SENSOR REMOVAL/INSTALLATION [MANUAL AIR CONDITIONER].)

SKYACTIV-D 1.5

1.  Install the manifold gauge. (See REFRIGERANT SYSTEM GENERAL PROCEDURES.)

2.  Verify the high-pressure side reading of the manifold gauge.

3.  Measure the terminal voltage at PCM terminal 2AR, 2BH and 2Z.

4.  Using the graph below, measure and verify the terminal voltage at 2BH.

5.  Follow the PCM inspection when measuring the other terminal voltages. (See PCM INSPECTION [SKYACTIV-D 1.5].)

•  Terminal 2AR: Approx. 5 V (Ignition switch on)

•  Terminal 2Z: 1.0 V or less

―  If the each voltage is not normal, inspect the related wiring harness.

•  If there is any malfunction, replace the related wiring harness.

•  If wiring harness is normal, replace the refrigerant pressure sensor. (See REFRIGERANT PRESSURE SENSOR REMOVAL/INSTALLATION [MANUAL AIR CONDITIONER].)
