Suction control valve circuit problem
DETECTION CONDITION
•  Any of following conditions occurs:
―  When the following conditions are met, the suction control valve control current 1.0 A or less for a continuous 1 s:
MONITORING CONDITIONS
•  Battery voltage: 8—20 V
•  Engine running

―  When the following conditions are met, the suction control valve control current exceeds 1.0 A for a continuous 1 s:
MONITORING CONDITIONS
•  Battery voltage: 8—20 V
•  Engine running
•  Suction control valve control duty value: 0 %
Diagnostic support note
•  This is an intermittent monitor (fuel system).
•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  PCM restricts engine torque.
•  Increase the idle speed.
•  Inhibits the EGR control.
•  Inhibits the diesel particulate filter regeneration control.
•  Inhibits engine-stop by operating the i-stop function.
•  PCM restricts engine-transaxle integration control.
POSSIBLE CAUSE
•  Suction control valve connector or terminals malfunction
•  Short to ground in wiring harness between the following terminals:
―  Suction control valve terminal A—PCM terminal 1CC
―  Suction control valve terminal B—PCM terminal 1BY
•  PCM connector or terminals malfunction
•  Short to power supply in wiring harness between the following terminals:
―  Suction control valve terminal A—PCM terminal 1CC
―  Suction control valve terminal B—PCM terminal 1BY
•  Suction control valve circuits are shorted to each other
•  Open circuit in wiring harness between the following terminals:
―  Suction control valve terminal A—PCM terminal 1CC
―  Suction control valve terminal B—PCM terminal 1BY
•  Suction control valve malfunction
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then 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.
No
Go to the next step.
3
INSPECT SUCTION CONTROL VALVE CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the suction control valve 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 10.
No
Go to the next step.
4
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR SHORT TO GROUND
•  Verify that the suction control valve connector is disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  Suction control valve terminal A
―  Suction control valve terminal B
•  Is there continuity?
Yes
If the short to ground circuit could be detected in the wiring harness:
•  Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected in the wiring harness:
•  Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 10.
No
Go to the next step.
5
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 10.
No
Go to the next step.
6
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR SHORT TO POWER SUPPLY
•  Verify that the suction control valve and PCM connectors are disconnected.
•  Switch the ignition ON (engine off).
•  Measure the voltage at the following terminals (wiring harness-side):
―  Suction control valve terminal A
―  Suction control valve terminal B
•  Is the voltage 0 V?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible short to power supply, then go to Step 10.
7
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR SHORT TO EACH OTHER
•  Verify that the suction control valve and PCM connectors are disconnected.
•  Switch the ignition off.
•  Inspect for continuity between suction control valve terminals A and B (wiring harness-side).
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to each other, then go to Step 10.
No
Go to the next step.
8
INSPECT SUCTION CONTROL VALVE CIRCUIT FOR OPEN CIRCUIT
•  Verify that the suction control valve and PCM connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Suction control valve terminal A—PCM terminal 1CC
―  Suction control valve terminal B—PCM terminal 1BY
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 10.
9
INSPECT SUCTION CONTROL VALVE
•  Inspect the suction control valve.
•  Is there any malfunction?
Yes
Replace the suction control valve, then go to the next step.
(See SUCTION CONTROL VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
10
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOER self test.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
DTC troubleshooting completed.
