Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
If the majority of the balance rates are positive and high, the dual-mass flywheel is causing a harmonic vibration that is affecting the engine fuel control system.
A dual mass flywheel concern will cause the balance rates to be inaccurate. The transmission concerns must be repaired before any fuel system diagnostic can be performed.
The Cylinder Power Balance Test may be performed at any engine speed or load from idle to wide open throttle (WOT). There is a 5-minute time limit for each test.
A high balance rate may be caused by a fuel injector or compression only if the ECM can control fuel pressure.
