ECD SYSTEM (w/o DPF) - Active Control Engine Mount System


DESCRIPTION

The Active Control Engine Mount (ACM) system decreases engine vibration at low engine speed using the VSV for engine mount. The VSV is controlled by a pulse signal transmitted to the VSV from the ECM. The frequency of this pulse signal is matched to the engine speed to decrease engine vibration.

INSPECTION PROCEDURE

HINT:
  1. After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
  2. Check the fuses for circuits related to this system before performing the following inspection procedure.
1.PERFORM ACTIVE TEST USING GTS

  1. Warm up the engine.

  1. Connect the GTS to the DLC3.

  1. Move the shift lever to N or P.

  1. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the ACM Inhibit.

  1. Hold the top part of the steering wheel, and turn the Active Test from OFF to ON. Check the engine vibration.

    Result:

2.CHECK VACUUM

  1. Check if the vacuum hose cap is missing, if the hose is damaged, and if the air and vacuum hoses have looseness, disconnection or blockage.

    OK:
    Vacuum hose cap is not missing and hoses are normal.


NG
REPLACE VACUUM HOSE
OK


3.INSPECT VSV FOR ENGINE MOUNT

  1. Inspect the VSV for engine mount (Click here).



NG
REPLACE VSV FOR ENGINE MOUNT (Click here)
OK


4.CHECK HARNESS AND CONNECTOR (VSV FOR ENGINE MOUNT - ECM)

  1. Disconnect the VSV for engine mount connector.

  1. Disconnect the ECM connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:

    for LHD
    Tester Connection
    		Condition
    		Specified Condition
    C81-2 - C45-52 (ACM)
    		Always
    		Below 1 Ω
    C81-2 or C45-52 (ACM) - Body ground
    		Always
    		10 kΩ or higher

    for RHD
    Tester Connection
    		Condition
    		Specified Condition
    C81-2 - C46-52 (ACM)
    		Always
    		Below 1 Ω
    C81-2 or C46-52 (ACM) - Body ground
    		Always
    		10 kΩ or higher


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


5.INSPECT ENGINE MOUNTING INSULATOR FRONT

  1. Inspect the engine mounting insulator front (Click here).
