If you experience a misre, knock, excessive smoke, or rough running
condition with no electrical DTCs, the Injector Balance Rate option
can help identify faulty injectors.
The balance rates are the fuel adjustments for each individual cylin-
der based on the variations in engine crankshaft speed. The balance
rates will change depending on if the transmission is in Neutral or
Drive. Monitor and record all cylinder balance rates in drive and
neutral. Injectors that read a higher numerical value than +/- 4.0
( e.g. +/- 5,6,7 etc.) in park/neutral and +/-6.0 in drive may identify
faulty injectors.
If the balance rates show a possible faulty injector, we recommend
you consult a professional diesel mechanic who can verify this test
and also perform a Cylinder Power Balance test to diagnose faulty
injectors.
