Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step Check Yes No
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 — (B134) No. 9:
(E55) No. 2 — (B135) No. 8:Is the resistance less than 1
Ω?Go to step 2.Repair the open
circuit between
ECM and tumble
generator valve
connector.
N
OTE:
In this case repair
the following:
Open circuit in
harness between
ECM and tumble
generator valve
actuator connec-
tor.
Poor contact in
coupling connector
2 CHECK POOR CONTACT.
Check poor contact in tumble generator valve
actuator connector.Is there poor contact in tumble
generator valve actuator con-
nector.Repair the poor
contact in tumble
generator valve
actuator connec-
tor.Replace the tum-
ble generator valve
assembly.
