DETECTION CONDITION

•  When the following condition is met, the PCM detects the control current at fuel injector No.2 as 0.67 A or less for continuous 8 times.

MONITORING CONDITIONS

―  During engine running

―  Battery voltage: 8 V or more

―  During fuel injection control

―  2 s or more have elapsed since PCM launch

―  The following DTCs are not detected:

•  PCM internal processor malfunction: P0606:00

•  Internal PCM malfunction: P062B:00

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA/Snapshot data is available.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

•  PCM restricts engine torque.

•  Inhibits the EGR control.

•  Inhibits the auto diesel particulate filter regeneration control.

•  Inhibits the compulsory diesel particulate filter regeneration control.

•  Inhibits engine-stop by operating the i-stop function.

•  PCM restricts engine-transaxle integration control. (ATX)

POSSIBLE CAUSE

•  Fuel injector No.2 connector or terminals malfunction

•  PCM connector or terminals malfunction

•  Open circuit in wiring harness between the following terminals:

―  Fuel injector No.2 terminal A—PCM terminal 1CW

―  Fuel injector No.2 terminal B—PCM terminal 1CT

•  Fuel injector No.2 malfunction

•  PCM malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the FREEZE FRAME DATA/snapshot data on the repair order.	—	Go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT FUEL INJECTOR NO.2 CONNECTOR CONDITION • Switch the ignition off. • Disconnect the fuel injector No.2 connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 7.
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 7.
4		No	Go to the next step.
5	INSPECT FUEL INJECTOR NO.2 CIRCUIT FOR OPEN CIRCUIT • Verify that the fuel injector No.2 and PCM connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side). ― Fuel injector No.2 terminal A—PCM terminal 1CW ― Fuel injector No.2 terminal B—PCM terminal 1CT • Is there continuity?	Yes	Go to the next step.
5		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals. • Fuel injector No.2 terminal A—PCM terminal 1CW • Fuel injector No.2 terminal B—PCM terminal 1CT If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has an open circuit. Go to Step 7.
6	INSPECT FUEL INJECTOR NO.2 • Inspect the fuel injector No.2. (See FUEL INJECTOR INSPECTION [SKYACTIV-D 1.5].) • Is there any malfunction?	Yes	Replace the fuel injector No.2, then go to the next step. (See FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
6		No	Go to the next step.
7	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) • Perform the KOER self test. (See KOEO/KOER SELF TEST [SKYACTIV-D 1.5].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].) Go to the next step.
7		No	Go to the next step.
8	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 1.5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
8		No	DTC troubleshooting completed.
