How to test the Ignition Control Module and related circuits on Ford Explorer?

This test assumes that the coil trigger signal has been checked and is not present at the ignition coil harness side connector. Special electronic test equipment is required to thoroughly test the ICM and related circuits. This test verifies the integrity of the most important circuits and assumes that, if the circuits are good the module is most likely defective. The Ignition Control Module is mounted to the radiator support behind the battery. Check for power to the ICM. Using a voltmeter, probe terminal number 8 (red wire +) and check for battery voltage. With the ignition ON (engine not running), there should be battery voltage. If battery voltage is not present, check the PCM power relay and related wiring for an open or shorted circuit. Turn the ignition OFF. Using an ohmmeter, check for continuity between terminal 9 of the ICM connector and battery ground. Continuity should exist. If no continuity exists, check the ground circuit for an open. Check the resistance of the crankshaft position (CKP) sensor on terminals number 5 and number 6. It should be between 2000 and 3000 ohms. If it isn't, check the crankshaft position sensor. Check the circuit from the ignition module to the SPOUT connector on terminal number 3 (pink wire +) for a complete circuit. Continuity should exist. If the test results are correct, replace the ignition module with a new one. Remove the battery. Disconnect the electrical connector from the ignition module. Remove the screw securing the Ignition Control Module to the radiator support. Slide the assembly up to remove the rivet from the positioning hole in the panel. Installation is the reverse of the removal.

Ford Explorer Ignition Control Module

The Ford Explorer Ignition Control Module manages the on off flow of coil current to create precise spark that lets the SUV start and run smoothly. By rapidly switching the primary circuit, the Ignition Control Module builds and collapses the coil magnetic field, stepping voltage up to the 15,000 plus needed to jump each spark plug gap for full combustion, better mileage and lower emissions. Early Ford Explorer models applied a distributor based Ignition Control Module that responded to signals from a reluctor and magnetic or hall pickup inside the distributor, with initial timing set by hand and advance handled by centrifugal and vacuum hardware. Later Ford versions moved to a distributorless style where the Ignition Control Module works with the powertrain computer, using crankshaft and sometimes camshaft sensors to decide exact firing moments, eliminating mechanical wear points and manual adjustment. Although more reliable, either Explorer design can fail, leading to no spark, rough running or starting trouble, and regular testing verifies the Ignition Control Module functions before it strands a Ford Explorer on the roadside.
