Control Module

Service on the Ignition Control Module begins by disconnecting all electrical connectors connected to the module's chassis. Record the original spark plug wire positions before you disconnect them from both ignition coils. Start by disconnecting the Ignition Control Module from the coil assemblies through screw removal and finally detach the coils from their position on the module. Next step involves removing the Ignition Control Module from the bracket assembly. Install the Ignition Control Module back onto its bracket before positioning the coils on top of the module. Refer to fastener notice in service precautions during this operation. Secure the screws back into position while tightening them to a torque setting of 4.5 n.m which equals 40 lb in. Reconnect the Spark Plug Wires according to the original order followed by installation of electrical connectors to the Ignition Control Module.

Before servicing the Ignition Control Module begin by disconnecting all electrical connectors at the icm while noting the spark plug wire positions before unclipping them from the ignition coils. The coil assemblies attach to the Ignition Control Module through screws that need removal before disconnecting the coils from their position. Start by removing the fasteners that keep the Ignition Control Module assembly fixed to the engine then extract the entire module from its bracket. Place the Ignition Control Module back on its bracket then mount the coils onto the module. Reinstall the fasteners which attach the Ignition Control Module assembly to the engine using the instructions in the service precautions section for safe fastener installation. Next install the screws by torquing them to 4.5 n.m (40 lb in). To finish the process connect the Spark Plug Wires following the removal sequence while also attaching the electrical connectors to the Ignition Control Module.

The Ignition Control Module is the second component that needs to be replaced. To do so, one has to first disconnect all the electrical connectors at the Ignition Control Module, record the position of the spark plugs for reinstallation purposes and then disconnect them from the ignition coils. After that, unscrew the screws holding the coil assemblies to the Ignition Control Module, and pull off the coils from the module, then take out the module from bracket. For installation, locate the Ignition Control Module back on the bracket and coil installation on to the module must be ensured while adhering to the fastener notice under service precauteness. Tighten the screws up to 4.5 n.m (40 lb in). Lastly, reconnect the Spark Plug Wires as pointed out during removal and plug the electrical connectors to the Ignition Control Module.

The first step to service the Ignition Control Module includes disconnecting all electrical connectors at the Ignition Control Module making a note of spark plug wire positions before removing Spark Plug Wires from ignition coils. Separate the coils from the Ignition Control Module by removing the bracket-perfecting screws before disconnecting the coils. Start by removing the engine bracket fasteners which hold the Ignition Control Module assembly in place and after that extract the Ignition Control Module from its bracket. Put the Ignition Control Module on its bracket first before reinstalling the coils. Following the fastener notice in cautions and notices secure the Ignition Control Module assembly to the engine with the fasteners before reinstalling screws that need to be tightened to 4-5 nm (40 lb in). Reattach the Spark Plug Wires according to removal steps while connecting the electrical connectors to the Ignition Control Module.

Begin servicing the Ignition Control Module by disconnecting all electric connectors connected to it. Note where Spark Plug Wires sit before their reinstallation then disconnect coil wires from the ignition coils. Run screws out of the coil assemblies which attach to the Ignition Control Module before removing the coils from the module. Unfasten the Ignition Control Module from its bracket. The install process involves attaching the Ignition Control Module to its bracket while re-mounting the coils onto the module with priority to follow the fastener notice guidelines in service precautions. Follow the fastener notice in service precautions to secure the coils by installing screws that reach 4.5 n.m (40 lb in of torque). Finish installation by attaching Spark Plug Wires according to initial removal procedure and connecting electrical connectors to the Ignition Control Module.

When replacing the Ignition Control Module start by disconnecting all electrical connectors before following the spark plug wire placement for installation to disconnect each wire from the Ignition Coil. First remove the screws which secure coil assemblies to the Ignition Control Module until you can take the coils away from the module. Next disconnect the Ignition Control Module from its mount position. Reinstall the coils to the module and place the Ignition Control Module onto the bracket according to the fastener notice displayed in service precautions. Apply 45 n.m (40 lb in) torque when you install screws into the coils to complete the installation process. Safely reinstall electrical connectors to ignite the control module before reconnecting Spark Plug Wires using their previous placement.

Before replacing the Ignition Control Module start by disconnecting the negative Battery Cable and proceed with further steps. Extract the 14-way electrical connector which belongs to the Ignition Control Module (ICM). Before disconnection note the original positions of Spark Plug Wires connected to coil assemblies. Start by using a screwdriver to remove Ignition Coil screws then extract all ignition coils from their position at the icm. Next remove the Ignition Control Module from its bracket position. Jeep grand cherokee does the assembly in two steps: add the Ignition Control Module to its bracket first and then position the ignition coils on top of the Ignition Control Module. Seal the Ignition Coil screws into place using 4.5 n.m (40 lb in) torque. Attach the Spark Plug Wires followed by connecting the module to its 14-way electrical connector and tightening the screw to 2.1 n.m (19 lb in). After you have completed all steps reconnect the negative Battery Cable.

Service operations on the Ignition Control Module require switching off ignition power first. Separate the 14-way connector from the Ignition Control Module while you remove the Spark Plug Wires from the coil assemblies, documenting their initial positions. Start by unscrewing and removing the 6 stud screws which bind the coil assemblies to the Ignition Control Module to finally remove the coils from the module. Washers and 2 nuts located beneath the module bracket enable detachment of the Ignition Control Module. Secure the module on the module bracket using two nuts and washers which should be tightened to 8 n.m (70 lb in). Connect each coil to its spot on the Ignition Control Module before tightening the 6 ignition coil attaching screws to 4.5 newton meters (40 pounds inch force). You should reconnect the Spark Plug Wires together with the 14-way connector to the module.

The first step in servicing an Ignition Control Module requires complete disconnection of all electrical connectors from the module. Note the spark plug wire arrangement for later installation then remove the wires from the ignition coils. To perform Ignition Coil servicing begin by removing screws holding coil assemblies to the Ignition Control Module. Afterward disconnect the coils from their module location. First detach all fasteners that hold the Ignition Control Module assembly to the engine and extract it from its bracket. The first step to install is placing the Ignition Control Module onto its bracket followed by fitting the coils onto the module. Reinstall the fasteners that join the Ignition Control Module assembly to the engine while strictly following the fastener notice provided in service precautions. Secure the screws by tightening them to 4-5 n.m (40 lb in). To complete the installation reconnect the Spark Plug Wires according to identified steps and join all electrical connectors to the Ignition Control Module.
