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. 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 (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, 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 (IGF)
signal to the ECM for each cylinder ignition.
DTC No. | DTC Detection Condition |

P0352 P0353 P0354 P0355 P0356 P0357
P0358 | No IGF signal to ECM while engine running

- Open or short in IGF or IGT circuit (1 to 8) between ignition coil and ECM
- No. 1 to No. 8 ignition coils
- ECM

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 stores a DTC. If the malfunction is not repaired successfully, a DTC is stored 1 second after the engine is next started. MONITOR STRATEGY

CAUTION / NOTICE / HINT
HINT: Read
freeze frame data using the Techstream. 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. PROCEDURE
