Code P1300 Description

Direct Ignition System (DIS) is a 1-cylinder ignition system that ignites one cylinder with one ignition coil. The 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 the 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 IGF circuit to ensure primary switching occurred. The P1300 code is for the ignition coil No.1 and is set when there is no IGF signal to the ECM during engine operation.
