DTC P2010 [MZR-CD (RF Turbo)]

BME010202000205

DTC P2010

Variable swirl control (VSC) solenoid valve circuit low input

DETECTION CONDITION

• The PCM monitors the output signal to the variable swirl control solenoid valve. If the voltage of the variable swirl control solenoid valve is less than 7.8 V even if the variable swirl control solenoid valve is off, the PCM determines that there is a malfunction in the variable swirl control solenoid valve control system.
Diagnostic support note
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• VSC solenoid valve malfunction
• Open circuit in wiring harness between VSC solenoid valve terminal A and PCM control relay terminal C
• Open circuit in wiring harness between VSC solenoid valve terminal B and PCM terminal 101
• Short to GND in wiring harness between VSC solenoid valve terminal B and PCM terminal 101
• Connector or terminal malfunction
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related service repair information availability.
• Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?
• Connect the WDS or equivalent to the DLC-2.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Start the engine.
• Is the PENDING CODE for this DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the "INTERMITTENT CONCERN TROUBLESHOOTING".
4
INSPECT POOR CONNECTION OF VSC SOLENOID VALVE CONNECTOR
• Turn engine switch to off.
• Disconnect the VSC solenoid valve connector.
• Inspect for poor connection (such as damaged/pulled-out terminals, corrosion).
• Is there any malfunction?
Yes
Go to the next step.
No
Repair or replace the suspected terminal, go to Step 10.
5
INSPECT VSC SOLENOID VALVE POWER SUPPLY FOR OPEN CIRCUIT
• Turn the engine switch to the ON position (Engine off).
• Measure the voltage between VSC solenoid valve terminal A (wiring harness-side) and body ground
• Is the voltage B+?
Yes
Go to the next step.
No
Repair or replace the wiring harness for an open circuit, go to Step 10.
6
INSPECT VSC SOLENOID VALVE CONTROL FOR SHORT TO GROUND
• Turn the engine switch off.
• Inspect for continuity between VSC solenoid valve terminal B (wiring harness-side) and body ground.
• Is there continuity?
Yes
Repair or replace the wiring harness for a short to GND, go to Step 10.
No
Go to the next step.
7
INSPECT VSC SOLENOID VALVE
• Inspect the VSC solenoid valve.
•  Is there any malfunction?
Yes
Replace the VSC solenoid valve, go to Step 10.
No
Go to the next step.
8
INSPECT POOR CONNECTION OF PCM CONNECTOR
• Turn the engine switch off.
• Disconnect PCM connector.
• Inspect for poor connection (such as damaged/pulled-out terminals, corrosion).
• Is there any malfunction?
Yes
Repair or replace the suspected terminal, go to Step 10.
No
Go to the next step.
9
INSPECT VSC SOLENOID VALVE CONTROL FOR OPEN CIRCUIT
• Turn the engine switch off.
• Inspect for continuity between VSC solenoid valve terminal B (wiring harness-side) and PCM terminal 101 (wiring harness-side).
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a short to GND, go to the next step.
10
VERIFY TROUBLESHOOTING OF DTC P2010 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Start the engine.
• Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, them go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
• Perform the Repair Verification Drive Mode.
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
