DESCRIPTION
HINT:
- These DTCs indicate a malfunction related to a primary circuit.
- If DTC P0351 is displayed, check No. 1 ignition coil circuit.
- If DTC P0352 is displayed, check No. 2 ignition coil circuit.
- If DTC P0353 is displayed, check No. 3 ignition coil circuit.
- If DTC P0354 is displayed, check No. 4 ignition coil circuit.
- If DTC P0355 is displayed, check No. 5 ignition coil circuit.
- If DTC P0356 is displayed, check No. 6 ignition coil circuit.
- If DTC P0357 is displayed, check No. 7 ignition coil circuit.
- If DTC P0358 is displayed, check No. 8 ignition coil circuit.
A Direct Ignition System (DIS) is used on this vehicle.
The DIS is a 1-cylinder ignition system which ignites one cylinder with one ignition coil. In the 1-cylinder ignition system, the one spark plug is connected to the end of the secondary winding. High voltage generated in the secondary winding is applied directly to the spark plug. The spark of the spark plug passes from the center electrode to the ground electrode.
The ECM determines the ignition timing and outputs the ignition signals (IGTs) for each cylinder. Using the IGTs, the ECM turns the power transistor inside the igniter on/off, which switches on/off current to the primary coil. When current to the primary coil is cut off, high voltage is generated in the secondary coil and this voltage is applied to the spark plugs to create sparks inside the cylinders. As the ECM cuts current to the primary coil, the igniter sends back ignition confirmation signals (IGFs) for each cylinder ignition to the ECM.
Reference: Inspect using an oscilloscope.
While cranking or idling the engine, check the waveform between terminals IGT1 to IGT8 and E1, and IGF1 to IGF2 and E1 of the E6, E8 and E6 ECM connectors.

Typical Enabling Conditions:
Typical Malfunction Thresholds:
Component Operating Range:
If the ECM does not receive an IGF after sending an IGT, it interprets this as a fault in the igniter and sets a DTC.

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.
- If DTCs P0351, P0354, P0356 and P0357 are output simultaneously, IGF1 circuit may be open or short.
- If DTCs P0352, P0353, P0355 and P0358 are output simultaneously, IGF2 circuit may be open or short.
