CAUTION:
Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO 2.0 (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. Ref. to ENGINE (DIAGNOSTICS) (H4DO 2.0 (EXCEPT FOR HEV))>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE
.
- CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH (SHORT TO POWER SUPPLY)
.
- Turn the ignition switch to OFF.
- Disconnect the connector from ECM.
- Measure the voltage between ECM connector and chassis ground.
Connector and terminal
(E158) No. 111 (+) - Chassis ground (-):
(E158) No. 102 (+) - Chassis ground (-):
Is the voltage 5 V or more?
Yes: Repair the short circuit to power in harness between ECM connector and tumble generator valve actuator RH connector.
No: Replace the tumble generator valve actuator RH. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO (EXCEPT FOR HEV))>TUMBLE GENERATOR VALVE ACTUATOR .
NOTE: The tumble generator valve actuator cannot be disassembled.
