DTC P2011: TGV Control Circuit/Open Bank 2: Notes
1. -
DTC detecting condition:
Immediately at fault recognition
Wiring diagram:
Engine Electrical System Ref. to WIRING SYSTEM>ENGINE ELECTRICAL SYSTEM .
Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>GENERAL DESCRIPTION>PREPARATION TOOL>HOW TO USE CHECK BOARD .
After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .
- CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR LH CONNECTOR (OPEN)
.
- Turn the ignition switch to OFF.
- Disconnect the connector from ECM.
- Disconnect the connector from tumble generator valve actuator LH.
- Measure the resistance of harness between ECM connector and tumble generator valve actuator LH connector.
Connector and terminal
(E53) No. 101 - (E110) No. 4:
(E53) No. 110 - (E110) No. 5:
Is the resistance less than 1 Ω?
Yes : Go to 2 .
No : Repair the open circuit in harness between ECM connector and tumble generator valve actuator LH connector.
- CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR LH CONNECTOR (SHORT TO GROUND)
.
Measure the resistance between the ECM connector and engine ground.
Connector and terminal
(E53) No. 101 - Engine ground:
(E53) No. 110 - Engine ground:
Is the resistance 1 MΩ or more?
Yes : Go to 3 .
No : Repair the short circuit to ground in harness between ECM connector and tumble generator valve actuator LH connector.
- CHECK FOR POOR CONTACT
.
Check for poor contact in the tumble generator valve actuator LH connector.
Is there poor contact of the tumble generator valve actuator LH connector?
Yes : Repair the poor contact of tumble generator valve actuator LH connector.
No : Replace the tumble generator valve actuator LH. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>TUMBLE GENERATOR VALVE ACTUATOR .
NOTE:The tumble generator valve actuator cannot be disassembled.
