DESCRIPTION
A direct ignition system is used on this vehicle.
The direct ignition system 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.

MONITOR DESCRIPTION
These DTCs are stored when a malfunction is detected in an ignition coil assembly circuit. If there is an open or short in an ignition coil assembly circuit, the ECM will illuminate the MIL and store a DTC.
WIRING DIAGRAM
PROCEDURE
PERFORM SPARK TEST
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs.
Powertrain > Engine > Clear DTCs
Turn the ignition switch off and wait for a few minutes.
Shuffle the arrangement of the ignition coil assemblies (among No. 1 to No. 3 cylinders).
Note:Do not change the location of the connectors.
Perform a spark test.
Enter the following menus: Powertrain / Engine / Trouble Codes.
