Ignition Coils/Modules
The electronic ignition system uses an individual ignition coil for each cylinder. There are two separate ignition module assemblies located in the camshaft cover of each cylinder bank. Each ignition module assembly contains an ignition control module and four ignition coils. Each ignition coil connects directly to a spark plug using a boot. This arrangement eliminates the need for secondary ignition wires. The ignition module assemblies receive power from a fused ignition feed. Both ignition module assemblies connect to chassis ground. A Reference Low and four ignition control (IC) circuits connect each ignition module assembly to the PCM. The PCM uses the individual IC circuits to control coil sequencing and spark timing for each ignition coil. The IC circuits transmit timing pulses from the PCM to the ignition control module to trigger the ignition coil and fire the spark plug. The PCM controls ignition system sequencing and timing events
Ignition "modulator"??? I assume you mean "ignition module" or "Ignition control module". If this is what you mean, it is mounted on the ignition coil assembly. Toyota refers to this part as "transistorized ignitor".
Ignition module sits in the ignition distributor, remove distributor cap, there will be two elec. harness plugs, the one with two wire's is for the pick up coil, the other one is for the ignition module, just unscrew module out of distributor and install new one.
The ignition module is generally located on top of the ECU for distributor cars. For distributorless ignition cars, the ignition module is usually inside the coil pack.
CONTROL MODULE-IGNITION
1996 Kia Sephia 1.6L MFI SOHC 4cyl
The Control Module-Ignition is located:
Under hood, driver side, front side of strut tower, rear of relay block, mounted under ignition coil
It does not have an ignition control module. The PCM (powertrain control module) fires the coil pack based on signal it recieves from the crankshaft position sensor and the camshaft position sensor.
Hi...
The Ignition module of your Century.
Is located UNDER THE IGNITION COILS.
The ignition coils are tie on the ignition module.
But LET ME tell you, something about your problem with the battery,
The Ignition Module is the LESS posible to Drain the Battry,
Because only use 3 connector, and the Ign. module is powered
with the ignition switch, is mean when you Turn the key to OFF.
All the power of the Ign. module Cut off.
If the ignition has no power when the car is OFF, impossible
Drain the battery,
I recomend check that all the lights went off after you close all the doors. Check the glove box light, Trunk light.
Some times the Factory Radio on chevys give up this problem, If the car is equipaded with a Aftermarket alarm.
You should check the circuit.
I'm a mechanic,
I hope this help on your problem.
Thank you for use fixya...
