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.

Non-turbo and turbo models use the same idle-up system, consisting of an air by-pass solenoid valve, A/C switch and relay, P/S switch, high altitude compensation, hot idle compensation, connecting hoses and electrical components.
