Ignition Module

The negatives Battery Cable requires removal as the first step to replace the Ignition Control Module (ICM). You should begin by taking off the intake manifold cover. To begin replacement of the icm wiring harness electrical connector you must first loosen the bolt securing the connector before disconnecting the connector from the icm. Next disconnect rear Spark Plug Wires from ignition coils before removing front Spark Plug Wires. Once the ignition coils are freed from their bolts you must extract them from the icm before you can extract the icm from its bracket. For installation position the icm on its bracket then install the ignition coils onto the icm while making sure all Ignition Coil bolts achieve a torque of 4.5 n.m (40 lb in). First connect rear plug wires to coils while installing both icm wiring harness connectors and securing their bolt. Install the intake manifold cover after reconnection of the negative Battery Cable. To access programming and setup instructions refer to control module references.

Start the Ignition Control Module replacement by first switching off ignition power followed by disconnecting the 14-way connector which connects to the Ignition Control Module (ICM). Remove Spark Plug Wires from coil assemblies keeping track of their original positions. The installation process begins with screw removal that attaches coil assemblies to the icm. Afterwards extract coils and the icm from their bracket. Installation requires attaching coils and Ignition Control Module to the bracket while adhering to the fastener notice in service precautions. Tighten all screws holding ignition coils and the icm to the bracket through torque settings of 4.5 n.m (40 lb in). Connect the Spark Plug Wires before connecting the module's 14-way connector by tightening its screw to 2.1 n.m (19 lb in).

In order to replace the Ignition Control Module you must first turn the ignition off and pull the 14-way connector from the Ignition Control Module (ICM). Next, remove the Spark Plug Wires from the coil assemblies, recording their position as well as where they are going to be disconnected from. Take out the screws that hold coil assemblies on icm, and then take out coils and icm out of the bracket. For installation, add the coils and the Ignition Control Module to the bracket and include screws to hold in place, tighten to 4.5 n.m (40 lb in). Connect the Spark Plug Wires and connect the 14-way connector to the module and tighten the screw with the tightening force of 2.1 n.m (19 lb in).

You should begin Ignition Control Module servicing by shutting off the ignition then detaching the 14-way connector which relays power to the module. Kelvin move the Spark Plug Wires from the coil assemblies while keeping track of their starting positions. Screw out the 6 holding screws which attach the coil assemblies to the Ignition Control Module before removing the coils from their housing. First remove the mounting bracket's washers and nuts followed by extracting the Ignition Control Module away from the bracket. The installation process requires attaching coils to the module bracket with 6 ignition coil attaching screws. Tighten the screws to a torque of 4-5 n.m (40 lb in). Secure the Ignition Control Module assembly to the mounting bracket by installing nuts and washers before tightening them to 8 n.m (70 lb in). Connect the Spark Plug Wires together along with the 14-way connector to the module for final installation.

To substitute the Ignition Control Module, let first the ignition off and remove the 14-way connector from the Ignition Control Module (ICM). Then, i'd remove the Spark Plug Wires from the coil assemblies recording their positions upon removal. Take out the screws that hold the coil assemblies to the icm and pull out the coils and icm from the bracket. For installation, mount the coils and the icm on the bracket and comply with the fastener notice that is contained in service precautions. Mount the screws that hold the ignition coils; together with the icm to the bracket, tighten to 4.5 n.m (40 lb in). Connect the spark plug cords and then attach the 14 way connector on the module, screw it very firmly to 2.1 (19 lb in).

Before replacing the Ignition Control Module turn the ignition off then disconnect the 14-way connector from the resistor block on the Ignition Control Module (ICM). Before wire removal keep track of spark plug wire placements. Start by removing screws that keep the coil assemblies fixed to the icm. Then extract the coils and the icm out from the bracket. Use the bracket to install the coils and Ignition Control Module before tightening the screws retaining both components to the bracket at 4.5 n.m (40 lb in). Follow by connecting the Spark Plug Wires followed by connecting the 14-way connector to the module and using a screw to tighten it to 2.1 n.m (19 lb in).

To replace the Ignition Control Module; first, turn off the ignition, then disconnect the Ignition Control Module (ICM) from the 14 way connector, may the position of the wires before removing them. Next, remove the coils assemblies' screws that fasten the coil assemblies to the icm then remove the Spark Plug Wires from the coil assemblies. Then take off the coils and the icm from the bracket. For installation, connect the coils to the bracket and the Ignition Control Module to the bracket, adhering to the fastener notice in service precautions. Fit the screws to secure the ignition coils and icm and the bracket with a torque of 4.5 n.m (40 lb in). Mount the module in the top hole and then tighten the mounting screw to 2.1 n.m (19 lb in). To ensure proper installation, double-check all connections and ensure that the module is securely fastened.

Turn off the ignition and remove the 14 way connector from the Ignition Control Module (ICM) (note the part position of the wires before disconnection). Next unscrew the Spark Plug Wires from the coil assemblies ,after that un screw the screws holding the coil assemblies to icm. Then take off the coils and the icm from the bracket. For installation, install the coils and Ignition Control Module to the bracket with reference to fastener notice in service precautions. Mount the screws to fix the ignition coils and the icm on the bracket and fasten them with a tightness of 4.5 n.m (40 lb in). So connect the Spark Plug Wires then connect the 14 way connector onto the module and tighten down the screw to 2.1 - n.m (19 - lb in).

Attach the coils to the ignition control module and position the ICM on the module bracket, ensuring to follow the Fastener Notice in Service Precautions.

Remove the screws securing the coil assemblies to the ICM, then take out the coils and the ICM from the bracket.

Remove the screws securing the coil assemblies to the ICM, then take out the coils and the ICM from the bracket.

Consult Control Module References.

Disconnect the rear spark plug wires from the ignition coils, followed by the front spark plug wires.

Disconnect the spark plug wires from the coil assemblies, noting their positions before removal.
