DTC P2008 [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)]

id0102c4840100

DTC P2008

Variable swirl control (VSC) solenoid valve control circuit open

DETECTION CONDITION

•  The PCM monitors the VSC solenoid valve control signal. If the following conditions are detected, the PCM determines that the VSC solenoid valve control circuit has a malfunction.

―  The PCM turns the VSC solenoid valve off, but the VSC solenoid valve control voltage is less than 5 V for 2 s (open circuit)

―  The PCM internal driver IC temperature is more than 150 °C {320 °F} when the VSC solenoid valve is on

POSSIBLE CAUSE

•  VSC solenoid valve malfunction

•  Connector or terminal malfunction

•  Open circuit in wiring harness between VSC solenoid valve terminal A and main relay

•  Open circuit in wiring harness between VSC solenoid valve terminal B and PCM terminal 181

•  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.
1		No	Record the FREEZE FRAME 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.
2		No	Go to the next step.
3	VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Connect the M-MDS to the DLC-2. • Clear the DTC from the PCM memory using the M-MDS. • Run the vehicle under the FREEZE FRAME DATA stored condition. • Is the same DTC present?	Yes	Go to the next step.
3		No	Intermittent concern exists. Perform the “INTERMITTENT CONCERNS TROUBLESHOOTING”. (See INTERMITTENT CONCERN TROUBLESHOOTING [WL-C, WE-C].)
4	INSPECT VSC SOLENOID VALVE CONNECTOR FOR POOR CONNECTION • Turn the engine switch off. • Disconnect the VSC solenoid valve connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 9.
4		No	Go to the next step.
5	INSPECT VSC SOLENOID VALVE CONTROL CIRCUIT 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.
5		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
6	INSPECT VSC SOLENOID VALVE • Inspect the VSC solenoid valve. (See VARIABLE SWIRL CONTROL (VSC) SOLENOID VALVE INSPECTION (Australian, European (L.H.D. U.K.) specs.) [WL-C, WE-C].) • Is there any malfunction?	Yes	Replace the VSC solenoid valve, then go to Step 9. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [WL-C, WE-C].)
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the engine switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 9.
7		No	Go to the next step.
8	INSPECT VSC SOLENOID VALVE CONTROL CIRCUIT FOR OPEN CIRCUIT • Turn the engine switch off. • Inspect for continuity between VSC solenoid valve terminal B (wiring harness-side) and PCM terminal 181 (wiring harness-side) • Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9	VERIFY TROUBLESHOOTING OF DTC P2008 COMPLETED • Turn the engine switch off. • Make sure to reconnect all disconnected connectors. • Turn the engine switch to the ON position (Engine off). • Clear the DTC from the memory using the M-MDS. • Run the vehicle under the FREEZE FRAME DATA stored condition. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [WL-C, WE-C].) (See PCM REMOVAL/INSTALLATION (U.K. Specs.) [WL-C, WE-C].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure“. (See AFTER REPAIR PROCEDURE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].) • Are any DTCs present?	Yes	Go to the applicable DTC troubleshooting. (See DTC TABLE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].)
10		No	Troubleshooting completed.
