10-11 1413-00 (3) Operating Steps Pre-Glow: Step 1 ▶ If normal communication with the ECU is established 2 seconds after the power is supplied to the IGN terminal from the battery, the GCU supplies the battery power to raise the temperature of the glow plug - The time for pre-heating is controlled by the ECU. If the input voltage (VB) is 11.5 V or less, GCU supplies the battery voltage for preheating time (T1). If the input voltage (VB) is greater than 11.5 V, GCU supplies the voltage of 11.5 V for preheating time (T1). - - The preheating time may vary according to the conditions. Input voltage VB (V) Pre-heating time T1 (sec) 6 8.27 7 5.8 8 4.1 9 3.15 10 2.4 11 1.95 ≥ 11.5 1.9 |
