  Q: Where is the Ignition Control Module (ICM) located, and How to test and remove it on Honda Prelude?

  A: The Ignition Control Module in the Accord and Prelude is tucked inside the distributor housing near the Ignition Coil, so to get to it you must pull the distributor cap back, remove the rotor, and if there is any, the dust cover. Position of the ignition wires on the distributor cap should also be identified by paper or by using other materials for identification to avoid misidentification or wrong replacement that might lead to replacement of the distributor cap and the consequent expensive charge. To test the Ignition Control Module on 2.2L and 2.3L engines start by disconnecting the distributor cap and a few wires from it and then check for battery voltage between the black/yellow and ground, then between green and ground wires. Continuity tests must be made between the yellow/green wire, the multi-connector and the Ignition Control Module with no continuity to ground. For the 2.7L engine, depending on the location, the harness connector might only consist of the yellow and green wires and the cap with wires on it; look for battery voltage on these wires and, similar to the previous engines, do continuity tests on other connections specified by the manufacturer. In the 3.0L engine, remove the distributor cap and then the 3 prong connector and verify voltage on No 2 & 3 terminals then check the continuity of Ignition Control Module and PCM leads. The Ignition Control Module can be removed by loosening the negative battery cable, then the distributor cap and rotor, and then pulling wires out of the Ignition Control Module before doing the reverse for installation. Lastly, if the battery is ever disconnected the PCM idle memory will have to be reset to normal by starting the engine and bringing it up to 3000 rpm for fan activation, allowing the engine to idle for five minutes without accessories and in Park or Neutral.
