REMOVAL & INSTALLATION
- Disconnect the negative battery cable.
- Detach all of the electrical connectors that are located at the top of the Ignition Control Module (ICM).
- Remove the mounting bolts, then remove the ICM from the vehicle.
- Installation is the reverse of the removal procedure.
The Powertrain Control Module (PCM) idle memory must be reset after reconnecting the battery. Start the engine and hold it at 3000 rpm until the cooling fan comes on. Then allow the engine to idle for about five minutes with all accessories OFF and with the transmission in Park or Neutral.
