DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
Step
1 CHECK HARNESS BETWEEN ECM AND
TUMBLE GENERATOR VALVE ACTUATOR
CONNECTOR.
1)Turn the ignition switch to OFF.
2)Disconnect the connector from tumble gen-
erator valve and ECM connector.
3)Measure the resistance between tumble
generator valve actuator and ECM connector.
Connector & terminal
(E55) No. 1 — (B84) No.4:
(E55) No. 2 — (B84) No.5:
2 CHECK POOR CONTACT.
Check poor contact in tumble generator valve
actuator connector.
Check
Is the resistance less than 1Ω? Go to step 2.
Is there poor contact in tumble
generator valve actuator con-
nector.
