What does Lexus P1310 code mean?
The Direct Ignition System (DIS) is a 1-cylinder ignition system that fires one cylinder with one ignition coil. The igniter is an integral part of 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, the power transistors in the igniter cut off the current to the ignition coil primary coil, causing the ignition coil to fire the spark plug. After giving the command to deactivate the primary circuit on the IGT wire, the ECM monitors the IGF circuit to ensure that primary switching has occurred.
