P1300 TOYOTA Description
Direct Ignition System (DIS) is a 1-cylinder ignition system that ignites one cylinder with one ignition coil. Ignitor is integral to the ignition coil. The Engine Control Module (ECM) determines the ignition timing and outputs an ignition signal (IGT) for each cylinder. Based on the IGT signals, power transistors in the ignitor cut of current to primary coil in the ignition coil, causing the ignition coil to fire the spark plug. After delivering a command to turn off the primary circuit on the IGT wire, ECM monitors the IGF circuit to ensure primary switching occurred.
