Subject: Direct ignition system (DIS) circuit diagrams for 1995–2003 Toyota OBD-II vehicles
Source: Toyota service manualsDirect ignition systems (DIS) rely on crankshaft, camshaft, and other sensors to inform the PCM (ECM) when to trigger the power transistor in each ignitor. When triggered, the power transistor stops the current through the primary coil winding, causing two spark plugs to fire.
Each DIS ignition coil fires two spark plugs simultaneously. After the spark plugs fire, the ignitor sends a signal back to the PCM via the IGF terminal. This allows the PCM to shut off fuel delivery should the ignitor fail, which prevents the catalytic converter from overheating.
Use the table below to locate the DIS circuit diagram for the vehicle being tested:
