CAUTION: Use the check board when measuring the ECM terminal voltage and resistance. Refer to ENGINE (DIAGNOSTICS) (H4DO (EXCEPT FOR HEV))>General Description>PREPARATION TOOL>HOW TO USE CHECK BOARD .

NOTE: After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Refer to ENGINE (DIAGNOSTICS) (H4DO (EXCEPT FOR HEV))>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .

CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR LH (OPEN) .
1. Turn the ignition switch to OFF.
2. Disconnect the connector from ECM.
3. Disconnect the connector from tumble generator valve actuator LH.
4. Measure the resistance of harness between ECM connector and tumble generator valve actuator LH connector.
  Connector & terminal
  
  (E158) No. 110 - (E51) No. 5:
  
  (E158) No. 101 - (E51) No. 4:
  
  Is the resistance less than 1 Ω?
  
  Yes:
  
  Go to 2.
  
  No:
  
  Repair the harness and connector.
  NOTE:
  In this case, repair the following item:
  - Open circuit in harness between ECM connector and tumble generator valve actuator LH connector
  - Poor contact of coupling connector
CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR LH (SHORT TO GROUND) .
Measure the resistance between ECM connector and chassis ground.

Connector & terminal

(E158) No. 110 - Chassis ground:

(E158) No. 101 - Chassis 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. Refer to FUEL INJECTION (FUEL SYSTEMS) (H4DO (EXCEPT FOR HEV))>TUMBLE GENERATOR VALVE ACTUATOR .

NOTE: The tumble generator valve actuator cannot be disassembled.
