DTC DETECTION LOGIC
DTCM.U.T.-III SE screen terms
(Trouble diagnosis content)
DTC detection condition
P200400SWIRL/TUMBLE CONT/V (B1)
(Intake manifold runner control stuck open bank 1)
Diagnosis condition—
Signal (terminal)Intake manifold runner control valve motor signal
ThresholdThe target angle of intake manifold runner control valve controlled by ECM and the input signal from intake manifold runner control valve position sensor is not in the normal range.
Diagnosis delay time—
 
 
POSSIBLE CAUSE
  • Harness or connectors (Intake manifold runner control valve motor circuit is open or shorted.)
  • Intake manifold runner control valve motor
 
 
FAIL-SAFE
Engine operating condition in fail-safe mode
Fail safe modeVehicle behavior
Traveling control modeEngine output controlECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle speed to encourage the driver to repair malfunction.
  • Driving at 70 km/h (44 MPH) or more is possible.
noteThis value is a reference value converted from engine power to vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition.
Device fix mode
  • This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position.
  • The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
  • A control signals is not transmitted to EGR volume control valve and the EGR volume control is deactivated.
Combustion control modeStratified charge combustion control at startingNo stratified charge combustion at starting (cold start).
 
 
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
TESTING CONDITION:
  • Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
  • Always perform the test at a temperature above −12°C (10°F)

2.PERFORM DTC CONFIRMATION PROCEDURE
With M.U.T.-III SE
  1. Turn ignition switch ON.
  2. Select “DATA MONITOR” mode with M.U.T.-III SE.
  3. Make sure that “COOLANT TEMP/S” indicates between −12°C (10°F) to 59°C (138°F).
    If not, cool engine down or warm engine up until “COOLANT TEMP/S” indicates between −12°C (10°F) to 59°C (138°F). Then go to the following steps.
  4. Fully release accelerator pedal and wait at least 10 seconds.
  5. Depress accelerator pedal and wait at least 10 seconds.
  6. Check 1st trip DTC.
 
With GST
Following the procedure “With M.U.T.-III SE” above.
 
Is 1st trip DTC detected?
