Relay box in engine compartment

(13) High speed

A. Overview

The supplementary electrical heater is installed in DI engine equipped vehicle as a basic

equipment. The PTC system is operated according to two temperature values measured at the

coolant temperature sensor and HFM sensor. This device is mounted in the heater air outlet and

increase the temperature of air to the passenger compartment. Because PTC system is heated by

electrical power, high capacity alternator is required. PTC does not operate during engine

cranking, while the battery voltage is lower than 11 V or during preheating process of glow plugs.
