TIER 2 SERVICE OVERVIEW

TIER 2 SERVICE OVERVIEW

Tier 2 is a computer-controlled fuel management system. A variety of sensors send input data to an ECU (Electronic Control Unit) that compares inputs with pre-programed memory and sends output voltage to a variety of actuators to adjust and operate the engine within specified parameters.

Tier 2 is a computer-controlled fuel management system. A variety of sensors send input data to an ECU (Electronic Control Unit) that compares inputs with pre-programed memory and sends output voltage to a variety of actuators to adjust and operate the engine within specified parameters.

The system is self-diagnostic with stored trouble codes displayed on a diagnostic gauge or read directly from a diagnostic connector. For reading service codes from the diagnostic gauge, see "Diagnostic Gauge" in CONTROLS. For more information about reading codes from the diagnostic connector, see "Diagnostic Blink Code Interpretation" on the next page.

For reading service codes from the diagnostic gauge, see "Diagnostic Gauge" in CONTROLS. For more information about reading codes from the diagnostic connector, see "Diagnostic Blink Code Interpretation" on the next page.

An operator alert indicator tells the operator when warning faults or engine shutdown faults develop. Warning faults occur when engine sensors indicate moderate trouble with coolant temperature, oil pressure, charge air temperature, or fuel temperature. Warning faults cause the operator alert indicator to flash, and the engine will begin a slow power derate. In some situations an alarm may also sound. A code is stored in the ECU. If the fault corrects itself, the engine will gradually return to normal power. The alert indicator will continue to flash until the trouble goes away, but a code will remain stored.

Engine shutdown will occur due to severe faults in engine coolant temperature, oil pressure, or fuel temperature. Before shutdown, the operator alert indicator will light continuously and the engine will begin a rapid power derate. If the fault does not improve in 30 seconds the engine will shut down.
