DESCRIPTION

УКАЗАНИЕ:
  1. These DTCs indicate malfunctions relating to the primary circuit.
  2. If DTC P0351 is set, check the No. 1 ignition coil circuit.
  3. If DTC P0352 is set, check the No. 2 ignition coil circuit.
  4. If DTC P0353 is set, check the No. 3 ignition coil circuit.
  5. If DTC P0354 is set, check the No. 4 ignition coil circuit.
  6. If DTC P0355 is set, check the No. 5 ignition coil circuit.
  7. If DTC P0356 is set, check the No. 6 ignition coil circuit.
  8. If DTC P0356 is set, check the No. 7 ignition coil circuit.
  9. If DTC P0356 is set, check the No. 8 ignition coil circuit.

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 spark plug is connected to the end of each secondary wiring. A powerful voltage, generated in the secondary wiring, is applied directly to each spark plug. The sparks of the spark plugs pass from the center electrode to the ground electrodes.
The ECM determines the ignition timing and transmits the ignition signals (IGT) 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, a powerful voltage 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, the igniter sends back an ignition confirmation signal (IGF) to the ECM, for each cylinder ignition.

MONITOR DESCRIPTION


A082388E07

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

УКАЗАНИЕ:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1.PERFORM SIMULATION TEST

  1. Clear the DTC(s) (see page Нажмите здесь).

  1. Change the arrangement of the ignition coils (with igniters).

    ПРИМЕЧАНИЕ:
    Do not change the location of the connectors.

  1. Perform a simulation test.
