Before testing this unit, disconnect the distributor cap alongside the ICM cover, and withdraw the wires from the ICM unit. To do this, turn the ignition ON (do not start the engine) and connect the voltmeter between black yellow small terminal of ICM unit and body ground; there must be battery voltage. If no voltage is found, check with a continuity tester the circuit between the black/yellow wire and the IGN switch. Then, enter into all BRN/BLK, and then measure voltage between white/blue wire and body ground there should be battery voltage. If missing, check the circuit between the wire related to the above and ignition coil. Also check the connection between the white/blue wire and the blue wire that is present with the offset terminal of the ICM it should of 1.1 to 3.3 K-ohms. If the ICM fails these checks, the ICM has to be replaced, and while installing the new ICM, sliding the connector into the housing, apply silicone grease. As to replacement, one begins with the removal of the negative battery terminal followed by distributor cap and cap cover, and then gets disconnecting all electrical connections of the ICM unit. Take out the two set screws at the ICM body and slide out the ICM unit along the axis of the rails. Removal is the process of 'un-installing,' and installation is the opposite of it.

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.

The ICM is integrated into each individual ignition coil on 3.0L Accord models with distributor-less ignition.
