Remove and replace the ignition control module on a 2017 Maserati Levante 3.0L V6 Twin Turbo, including removal of engine covers and ignition coils to access the module.

Warnings

Tools required

Parts

• Ignition Control Module × 1 — Use OEM specification
• Engine cover grommets (if damaged) × 1 — Use OEM specification

Preparation

1. Ensure engine is completely cool to the touch (wait at least 2 hours after last operation)
2. Park vehicle on level surface and engage parking brake
3. Disconnect battery negative terminal and wait 10 minutes for system discharge
4. Remove engine cover by pulling upward firmly to release mounting grommets
5. Take photographs of all wiring harness routing and connections for reference

Procedure

1. 1

   Remove decorative engine covers
   Remove the plastic engine cover by pulling upward to release the grommets. If present, remove any additional plastic covers over the ignition coils using T25 Torx screws. Inspect grommets for damage and replace if cracked or torn.

   Cover Screws11 Nm (8 lb-ft)
2. 2

   Locate ignition control module
   The ignition control module is mounted on the left (driver) side of the engine valley, near the firewall, between the cylinder banks. It is a rectangular black or silver box with multiple electrical connectors. Clear any harness or hose routing that obstructs access to the module.
3. 3

   Disconnect ignition coil connectors
   Disconnect all six ignition coil electrical connectors by pressing the locking tab and pulling straight up. Mark each connector with tape corresponding to cylinder number if not already marked by manufacturer. This provides access to the module below.
4. 4

   Remove ignition coils if necessary
   If the ignition control module is blocked by ignition coils, remove the necessary coil mounting bolts (typically cylinders 2, 4, and 6 on the left bank). Pull each coil straight up with a twisting motion to break the seal with the spark plug. Set coils aside in order.
   ⚠Do not pull on ignition coil wires. Grip only the coil body when removing to prevent damage to internal components.

   Ignition Coil Bolts8 Nm (6 lb-ft)
5. 5

   Disconnect module electrical connectors
   The ignition control module has 2-3 large multi-pin connectors. Slide back the red safety lock on each connector, then press the release tab while pulling the connector straight away from the module. Use electrical contact cleaner to spray any dirt or oil from the connector area.
6. 6

   Remove module mounting hardware
   Remove the ignition control module mounting bolts using a 10mm socket. There are typically 2-3 bolts securing the module to its bracket. If a ground wire is present, note its location for reinstallation. Support the module as you remove the final bolt.
   Torque spec

   Mounting Bolts28 Nm (21 lb-ft)
7. 7

   Remove ignition control module
   Carefully lift the ignition control module straight up and away from the mounting bracket. Inspect the mounting surface for corrosion or damage. Clean the mounting area with a clean shop towel and compressed air if available.
8. 8

   Prepare new ignition control module
   Remove the new ignition control module from its protective packaging. Inspect all connector pins for damage or corrosion. Apply a thin coat of dielectric grease to the connector seals (not the pins themselves) to prevent moisture intrusion.
   ⚠Do not apply dielectric grease to connector pins as this can cause poor electrical contact. Apply only to rubber seals.
9. 9

   Install new ignition control module
   Position the new ignition control module onto the mounting bracket, ensuring it is fully seated and aligned with mounting holes. Install mounting bolts finger-tight first, then torque to specification in a cross pattern. Reconnect any ground wires if present.

10. 10

    Reconnect module electrical connectors
    Connect each electrical connector to the ignition control module, ensuring they click into place securely. Push the red safety lock forward to secure each connector. Verify all connectors are fully seated by gently pulling on them.
11. 11

    Reinstall ignition coils
    If ignition coils were removed, inspect the spark plug wells for debris or oil. Clean if necessary. Apply a thin coat of dielectric grease to the inside of each ignition coil boot. Install each coil by aligning with the spark plug and pushing down firmly until fully seated. Install and torque coil mounting bolts.

12. 12

    Reconnect ignition coil connectors
    Reconnect all six ignition coil electrical connectors, ensuring each connector clicks into place. Match cylinder numbers with your reference photos. Verify all connections are secure.
13. 13

    Reinstall engine covers
    Reinstall any plastic covers over ignition coils, torquing T25 Torx screws to specification. Reinstall the main engine cover by aligning grommets with mounting posts and pressing down firmly until seated. Replace any damaged grommets.

Reassembly

1. Verify all electrical connectors are fully seated and locked
2. Ensure all tools and parts are removed from engine bay
3. Reconnect battery negative terminal
4. Double-check that engine cover is properly seated on all grommets

Verification

• Turn ignition to ON position (do not start) and verify no warning lights related to ignition system appear on dashboard
• Start engine and listen for smooth idle with no misfires or rough running
• Use scan tool to verify no diagnostic trouble codes (DTCs) are present
• Test drive vehicle under various load conditions to confirm proper ignition timing and performance
• Verify all cylinders are firing properly by monitoring engine smoothness during acceleration
• After test drive, inspect module area for any loose connections or unusual heat buildup
