How to igniter and pick up coils for Toyota 4A-FE?
Note: This procedure applies only to the 1.6 litre 4A-FE engine. 1 Ensure the ignition is switched off. 2 Disconnect the electrical connector at the distributor and, using an ohmmeter, measure the resistance between the pick-up coil terminals (see illustration). 3 Compare the measurements to those listed in this Chapter’s Specifications.
When to replace an ICM / ECU ignition system?
It is far more likely that a bad connector or wire the is cause of the problem than the black box. With that in mind do not even consider replacing an ICM/ECU unless you are 100% confident that all ignition system components, switches, wires and connectors are in perfect working order.
What kind of signal does a pickup coil need?
For example a blue/white signal wire from the pickup coil needs to have continuity between its terminal where it connects to the harness from the coil, and its terminal where the harness connects to the ECM.
Can a faulty ECM cause a no spark condition?
It is extremely rare for a no spark condition to be the result of a faulty coil or ECM. Users get fixated on these items and jump to the conclusion they must be responsible for their problem because these items are easy to see and replace. This is the opposite of the strategy needed to fix a no spark condition.
How does the Ignition Control Module ( ICM ) work?
The ignition control module (ICM), upon receiving this PIP signal, starts to ‘open and close’ the ignition coil’s primary current. As you might already be aware, it’s this action that makes the ignition coil spark. The fuel injection computer also receives the PIP Signal at the same time that the ignition module does.

How is the PIP signal sent to the ignition module?
The ignition control module also sends a Profile Ignition Pick (PIP) signal that the PCM uses to start activating the fuel injectors. The PIP signal is sent to the PCM thru’ the wire labeled with the number 1. The PIP signal is only sent after the ignition module gets the crank sensor signal.
