How to test ignition control modules without an approved ignition control module tester on Jeep Comanche?

You need an approved ignition control module tester to test the ignition control modules used. Without this equipment, module testing is beyond the scope of the home mechanic. If you have access to the necessary tool, the instructions for testing the module are provided by the manufacturer. For V6 models, detach the cable from the negative battery terminal. Remove the distributor cap and rotor. Remove the two control module attaching screws and lift the module up. Detach the pickup coil wire connector from the module, noting the wire colors. Disconnect the wire harness connector. If you will be reinstalling the old module, don't wipe the grease from the module or the distributor base. If you install a new module, spread the included silicone dielectric compound on the metal face of the module and on the distributor base where the module seats. For inline six-cylinder models, remove the ignition coil. Remove the two screws that attach the module to the coil frame. Pull off the module. Installation is the reverse of removal.

Jeep Comanche Ignition Control Module

The Jeep Comanche Ignition Control Module activates and deactivates coil current at the precise time each cylinder requires spark to ensure strong combustion and easy starting. The Ignition Control Module in the early trucks dwelt inside an electronic distributor which applied to watch a magnetic pickup or hall sensor on the reluctor wheel. Its transistor applied to snap the primary circuit open and closed quicker than the breaker points. This was meant for higher voltage and steadier running. The system installed on the Jeep Comanche applied the original Ignition Control Module to allow for manual base timing and centrifugal or vacuum advance. Subsequent modifications in the 4.0-liter editions introduced the concept of distributorless ignition. In this version, a revised Ignition Control Module worked in tandem with the engine computer. It read the crankshaft position signal and fired the coils. This design also saw the removal of mechanical wear parts. Other additions like the locking of the timing under software were made to the Comanche for improving power, mileage, and emissions. When there is no flicker at the negative coil post when cranking, the Ignition Control Module is on the top of the suspect list because, without its fast switching, the magnetic field cannot collapse. Quick validation of the voltage aids Jeep lovers in maintaining the legendary Jeep heritage and keeping every Comanche firing reliably.
