DESCRIPTION
HINT:
-
These DTCs indicate malfunctions relating to the primary circuit.
-
If DTC P035113 is output, check the No. 1 ignition coil assembly circuit.
-
If DTC P035213 is output, check the No. 2 ignition coil assembly circuit.
-
If DTC P035313 is output, check the No. 3 ignition coil assembly circuit.
-
If DTC P035413 is output, check the No. 4 ignition coil assembly 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 assembly 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 spark of the spark plugs passes 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 the current supplied to the primary coil on and off. 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.

Reference: Inspection using an oscilloscope.
HINT:
-
The correct waveform is as shown.
-
With the engine idling, check the waveform between terminals IGT (1 to 4) and E1, and IGF1 and E1 of the ECM connector.

CH1: Between IGT (1 to 4) and E1
CH2: Between IGF1 and E1
|
Tester Range
|
2 V/DIV., 20 ms./DIV.

Condition
|
Idling with warm engine
|
MONITOR DESCRIPTION
If the ECM does not receive any IGF signals despite transmitting the IGT signal, it interprets this as a malfunction of an igniter and stores a DTC.

CAUTION / NOTICE / HINT
NOTICE:
-
Inspect the fuses for circuits related to this system before performing the following procedure.
-
Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

- for Lithium-ion Battery: Click here
(Select Powertrain in Health Check and then check the time stamp data.)
Click here
-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs.
Powertrain > Engine > Clear DTCs
(e) Turn the power switch off and wait for at least 30 seconds.
