(See DTC TABLE [PCM (SKYACTIV-D 2.2)])
		No	Go to the next step.
3	INSPECT COOLANT CONTROL VALVE/COOLANT CONTROL VALVE POSITION SENSOR CONNECTOR CONDITION •  Switch the ignition OFF. •  Disconnect the coolant control valve/coolant control valve position sensor connector. •  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector, then go to Step 10.
4	INSPECT PCM CONNECTOR CONDITION •  Disconnect the PCM connector. •  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector, then go to Step 10.
5	INSPECT COOLANT CONTROL VALVE CONTROL CIRCUIT FOR SHORT TO GROUND •  Verify that the coolant control valve/coolant control valve position sensor connector and the PCM connector are disconnected. •  Inspect for continuity between the following terminals (vehicle wiring harness side) and ground. ―  Coolant control valve/coolant control valve position sensor terminal C •  Is there continuity?	Yes	Refer to the wiring diagram and verify if there is a common connector between the following terminals. •  Coolant control valve/coolant control valve position sensor terminal C and PCM terminal 1BO If there is a common connector: ―  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location. ―  Repair or replace the malfunctioning location. If there is no common connector: ―  Repair or replace the wiring harness which is shorted to ground. Go to Step 10.
		No	Go to the next step.
6	INSPECT COOLANT CONTROL VALVE CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY •  Verify that the coolant control valve/coolant control valve position sensor connector is disconnected. •  Switch the ignition ON (engine off). Note •  Another DTC may be stored by the PCM detecting an open circuit. •  Measure the voltage at the following terminals (vehicle wiring harness side). ―  Coolant control valve/coolant control valve position sensor terminal E •  Is the voltage 0 V?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify if there is a common connector between the following terminals. •  Coolant control valve/coolant control valve position sensor terminal E and PCM terminal 1BN If there is a common connector: ―  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to power supply to determine the malfunctioning location. ―  Repair or replace the malfunctioning location. If there is no common connector: ―  Repair or replace the wiring harness which is shorted to the power supply. Go to Step 10.
7	INSPECT COOLANT CONTROL VALVE CONTROL CIRCUIT FOR OPEN CIRCUIT •  Switch the ignition OFF. •  Verify that the coolant control valve/coolant control valve position sensor connector is disconnected. •  Inspect between the following terminals (vehicle wiring harness side) for continuity. ―  Coolant control valve/coolant control valve position sensor terminal A and PCM terminal 1AO ―  Coolant control valve/coolant control valve position sensor terminal B and PCM terminal 1AJ ―  Coolant control valve/coolant control valve position sensor terminal C and PCM terminal 1BO ―  Coolant control valve/coolant control valve position sensor terminal E and PCM terminal 1BN •  Is there continuity?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify if there is a common connector between the following terminals. •  Coolant control valve/coolant control valve position sensor terminal A and PCM terminal 1AO •  Coolant control valve/coolant control valve position sensor terminal B and PCM terminal 1AJ •  Coolant control valve/coolant control valve position sensor terminal C and PCM terminal 1BO •  Coolant control valve/coolant control valve position sensor terminal E and PCM terminal 1BN If there is a common connector: ―  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location. ―  Repair or replace the malfunctioning location. If there is no common connector: ―  Repair or replace the wiring harness which has an open circuit. Go to Step 10.
8	INSPECT COOLANT CONTROL VALVE •  Inspect the coolant control valve. (See COOLANT CONTROL VALVE INSPECTION [SKYACTIV-D 2.2]) •  Is the coolant control valve normal?	Yes	Go to the next step.
		No	Replace the coolant control valve, then go to Step 10. (See COOLANT CONTROL VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
9	INSPECT COOLANT CONTROL VALVE POSITION SENSOR •  Reconnect all the disconnected connectors. •  Inspect the coolant control valve position sensor. (See COOLANT CONTROL VALVE POSITION SENSOR INSPECTION [SKYACTIV-D 2.2]) •  Is the coolant control valve position sensor normal?	Yes	Go to the next step.
		No	Replace the coolant control valve, then go to the next step. (See COOLANT CONTROL VALVE POSITION SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
10	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Reconnect all the disconnected connectors. •  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC. (See CLEARING DTC [PCM (SKYACTIV-D 2.2)]) •  Perform the KOEO self-test. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Is DTC P2B61:00 displayed?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
