Cyl (#) balance max limit exceeded

Cylinder Balance Operation

Many factors influence the combustion process in a power cylinder. This can affect the production of torque or horsepower from that cylinder. Some of the factors include piston and cylinder geometry, injector performance, and rail pressure. Variations in these factors can cause unevenness in torque and horsepower from one cylinder to the next. Power cylinder unevenness also causes increased engine noise and vibration, especially at low idle conditions. This is also referred to as rough idle.

The ECM uses a Cylinder Balance control strategy to even the power contribution of the cylinders, particularly at low idle conditions. This strategy incorporates information from the crankshaft position system. The ECM uses the instantaneous engine speed near Top Dead Center (TDC) for each cylinder as an indication of that cylinder's power contribution. The ECM computes a nominal instantaneous engine speed value based on all cylinders. The nominal value would be the expected value from all cylinders if the engine is balanced. By knowing the error quantities, the ECM can add or subtract fuel from a particular cylinder. The control strategy attempts to correct the cylinder unbalance by using fuel quantity compensation through adjustments of the pulse width values for each fuel injector. This method of compensation is repeated until all error quantities are close to zero causing all cylinders to contribute the same amount.

DTC

Condition

Possible Causes

4561-4566

4571-4576

Cyl (#) balance below min limit

Cyl (#) balance max limit exceeded

  • Electrical fault
  • Low fuel pressure
  • Aerated fuel
  • Contaminated fuel
  • EGR valve stuck open
  • Injection control system
  • Failed injector
  • Base engine compression imbalance

DTC 4561-4566 - Cylinder (#) balance below min limit

DTC 4571-4576 - Cylinder (#) balance max limit exceeded

The ECM continuously calculates the balance of each cylinder during normal engine operation. If a cylinder is under or over performing, a cylinder balance DTC will be set.

Pin-point Cylinder Balance Fault

  1. Visually inspect engine for damaged or disconnected components.

    • Check all fluid levels.
    • Check engine and control system for electrical or mechanical damage.

     

  2. Check for other active DTCs that could cause a cylinder imbalance.

    • If injector electrical faults are set, diagnose the electrical fault before diagnosing a cylinder imbalance.

     

  3. Check fuel pressure, fuel aeration, and possible fuel contamination.

    Note: These checks can be verified quickly by using the Fuel Pressure Test Gauge with shut-off valve. See Fuel Pressure and Aeration test in the "Hard Start and No Start" section of this manual.

  4. Check ICP pressure and voltage.

    • Check ICP voltage at KOEO.
    • See "Performance Specifications" appendix in this manual for specification.
    • Check ICP system pressure during KOER. Run KOER Standard Test.
    • See "Performance Specifications" appendix in this manual for specification.

     

  5. Inspect EGR valve. Verify valve is not stuck open.

    • Run KOEO Standard Test
    • Run KOER Air Management Test.

Repair any faults found in any of the preceding checks before continuing.

  1. Run KOER Injector Disable Test to identify imbalanced cylinder.

  2. Run Relative Compression Test to verify if cylinder imbalance is mechanical issue or injector issue.

    If the Relative Compression Test fails the same cylinder as indicated by Injector Disable Test, the fault is a mechanical failure.

    • Check crankcase pressure.
    • Check valve lash and brake lash (if equipped).

I've run the compression test run the disable test run the air management test run the standard tests EGR valve is brand-new ICP is brand-new and I run those tests also

I would get a mechanical gauge on it and monitor fuel pressure as well as install a clear hose or site glass inline for the suction and return to monitor for air bubbles or fluctuations of fuel pressure, etc

Customer reply replied 2 years ago
What will it mean if i have air bubbles on suction side or return side. Also what should my gauge read
Technician: Daniel Wilson,
 replied 2 years ago

It would mean you are sucking in air somewhere causing an aeration of fuel possible small leak on the suction side, damaged injector oring, etc. Service Max may not pick that up from the sensors.

If one of the injector pumps in the high-pressure rail was bad with that cause air

Cups not pumps

Yes that is definitely a possibility.
