What are the functions and removal process of the Ignition Control Module on Cadillac Fleetwood?

The ICM is mounted on the top part of the 4.6L rear camshaft cover and is responsible for the following functions In addition to monitoring ON-OFF pulses from the crankshaft and camshaft position sensors, is responsible for generating a camshaft reference signal for controlling the ignition and fuel injection as well as providing the PCM with a ground reference and allowing the PCM to vary the amount of spark advance. The ICM is nonrepairable, and when replacing the module, the remaining components are transferred to the new one. To perform the removal of the ICM, spark plug wires and four electrical connectors must be disconnected, four bolts illustrated in the steps that hold the module to the rear camshaft cover must be unbolted, module assembly has to be taken out of the vehicle and ignition coils removed from the assembly.

Cadillac Fleetwood Ignition Control Module

The Cadillac Fleetwood Ignition Control Module supervises the on off flow of coil current, delivering the precise spark timing that lets the luxury sedan start quickly and run smoothly. Early versions in seventies and eighties Cadillac Fleetwood models sat inside the electronic distributor, where the module's transistor switched the primary circuit far faster than old breaker points, boosting voltage to the plugs for stronger combustion. This distributor style Ignition Control Module relied on a magnetic pickup or hall effect switch and a spinning reluctor to trigger it, while centrifugal and vacuum devices still managed advance. Later years adopted distributorless systems, moving timing decisions to the engine computer but still tasking an Ignition Control Module with rapid primary current interruption based on signals from the crankshaft position sensor. By eliminating mechanical play in gears and chains, the newer Ignition Control Module setup sharpened spark accuracy, improved fuel economy and lowered emissions. Despite greater reliability, heat and age can cause any Ignition Control Module to fail, producing no flicker at the test light on the coil negative and leaving the engine unable to start. Whether tucked inside a classic distributor or paired with computer control in a later Cadillac Fleetwood, both types share the same goal, quick coil switching for dependable spark.

Each OEM Cadillac Fleetwood Ignition Control Module we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
