Engine Mount: Testing and Inspection

Active Control Engine Mount

CIRCUIT DESCRIPTION
Active control engine mount (ACM) system dampens engine vibration at low engine speed using ACM VSV. The VSV is controlled by a pulse signal transmitted to the VSV from the engine control module (ECM). In normal operation, the frequency of this pulse signal is correctly matched to engine speed to effectively dampen engine vibration.
