1.CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM.
3) Measure the voltage between ECM connector and chassis ground.
Connector & terminal
(B134) No. 25 (+) — Chassis ground (−):
(B134) No. 14 (+) — Chassis ground (−):
Is the voltage 5 V or more?
Repair the short circuit to power in harness between ECM connector and tumble generator valve actuator RH connector.
Replace the tumble generator valve actuator RH. Tumble Generator Valve Actuator">
1. OUTLINE OF DIAGNOSIS
Detect the open or short circuit of tumble generator valve motor.
Judge as NG when the overcurrent signal is sent from IC after tumble generator valve driving IC diagnosis.
2. COMPONENT DESCRIPTION

(1) | Engine control module (ECM) | (2) | Tumble generator valve | (3) | Battery |
3. EXECUTION CONDITION
Secondary Parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
TGV command | = Open or = closed |
4. GENERAL DRIVING CYCLE
Always perform the diagnosis continuously.
5. DIAGNOSTIC METHOD
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Malfunction Criteria | Threshold Value |
Overcurrent signal from driver IC Short circuit to GND is detected when IC current > 16 A or Short circuit to B+ is detected when IC current > 14 A | = ON |
Time Needed for Diagnosis: 1 second
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
