Idle-Up System: Description

The idle-up systems are used on those models with engine powered accessories that decrease engine RPM. To maintain proper engine performance, the idle-up system increases the engine RPM to the required specifications.

B2200 models with A/C use an idle-up system, consisting of a 3-way solenoid valve, servo diaphragm, connecting hoses and electrical components.

B2600 models with A/C use an idle-up system, consisting of a idle-up solenoid valve, servo diaphragm, connecting hoses and electrical components. Models with automatic transmission (A/T) also have a Power Steering (P/S) switch (if equipped).
