  2. Remove the four electrical connectors at the ignition control module.

  3. Object Number: 11760  Size: SH
  4. Remove the four bolts (4 and 8) retaining the IC module assembly to rear camshaft cover (5).
  5. Remove the IC module assembly from the vehicle.
  6. Remove the ignition coils from the IC module assembly (1, 2, 3, and 7).
  7. Remove the IC module from the assembly bracket (6).

Installation Procedure


    Object Number: 11760  Size: SH
  1. Install the IC module to the assembly bracket (6).
  2. Install the ignition coils to the IC module assembly.
  3. Position the IC module assembly on the rear camshaft cover and install the four retaining bolts (4 and 8).
  4. Tighten
    Tighten the 4 retaining bolts to 12 N·m (106 lb in). Refer to

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
