2002 Toyota Tacoma Igniter Circuit Malfunction

A Direct Ignition System (DIS) has been adopted. The DIS improves the ignition timing accuracy, reduces high–voltage loss, and enhances the overall reliability of the ignition system by eliminating the distributor. The DIS is a 2–cylinder simultaneous ignition system which ignites 2 cylinders simultaneously with 1 ignition coil. In the 2–cylinder simultaneous ignition system, each of the 2 spark plugs is connected to the end of the secondary winding. High voltage generated in the secondary winding is applied directly to the spark plugs. The sparks of the 2 spark plugs pass simultaneously from the center electrode to the ground electrode. The ECM determines ignition timing end outputs the ignition signals (IGT) for each cylinder. Based on IGT signals, the igniter controls the primary ignition signals (IGC) for all ignition coils. At the same time, the igniter also sends an ignition confirmation signal (IGF) as a fail–safe measure to the ECM.

2004-2007 Mazda RX-8 Engine Cranks No Start Service Bulletin

Some vehicles (mazda rx-8) may experience difficulty starting (cranks no start). This may occur after driving the vehicle a
short distance without engine reaching normal operating temperature. Examples: starting a vehicle and moving
it to wash it, engine stall due to mis-application of clutch then restart. This commonly occurs at port facilities or
dealer lots where vehicles are frequently started cold, moved for short distances and then turned off. This concern may also occur due to low cranking RPM during engine starting.
