DESCRIPTION

A Direct Ignition System (DIS) is used on this vehicle.

The DIS is a 1-cylinder ignition system in which each cylinder is ignited by one ignition coil and one spark plug is connected to the end of each secondary wiring. High-voltage is generated in the secondary wiring and then applied directly to each spark plug. The sparks of the spark plugs pass from the center electrodes to the ground electrodes.

The ECM determines the ignition timing and transmits the ignition (IGT) signals to each cylinder. Using the IGT signal, the ECM turns the power transistor inside the igniter on and off. The power transistor, in turn, switches on and off the current to the primary coil. When the current to the primary coil is cut off, highvoltage is generated in the secondary coil. This voltage is applied to the spark plugs, causing them to spark inside the cylinders. As the ECM cuts the current to the primary coil off, the igniter sends back an ignition confirmation (IGF) signal to the ECM, for each cylinder ignition.

No IGF signal to ECM while engine is running (1 trip detection logic)
  • Ignition system
  •  Open or short in IGF1 or IGT circuit (1 to 6) between ignition coil with igniter and ECM
  •  No. 1 to No. 6 ignition coils with igniters
  •  ECM

Reference: Inspection using an oscilloscope

DESCRIPTION

While cranking or idling, check the waveform between terminals IGT (1 to 6) and E1, and IGF1 and E1 of the ECM connector

DESCRIPTION

MONITOR DESCRIPTION

MONITOR DESCRIPTION

If the ECM does not receive any IGF signals despite transmitting the IGT signal, it interprets this as a fault in the igniter and sets a DTC.

If the malfunction is not repaired successfully, a DTC is set 1 second after the engine is next started.

INSPECTION PROCEDURE

HINT: Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
