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
(E51) No. 1 — (B134) No. 11:
(E51) No. 2 — (B134) No. 10:
2 CHECK POOR CONTACT.
Check poor contact in tumble generator valve
actuator connector.
Check
Is the resistance less than 1 Ω? Go to step 2.
Is there poor contact in tumble
generator valve actuator con-
nector?
EN(H4DOTC 2.5)-206
Yes
Repair the open
circuit between
ECM and tumble
generator valve
connector.
NOTE:
In this case repair
the following:
• Open circuit in
harness between
ECM and tumble
generator valve
actuator connector.
• Poor contact in
coupling connector
Repair the poor Replace the tum-
contact in tumble ble generator valve
