LOCATION



The Ignition Control Module (ICM) on the Civic and Civic del Sol is located in the distributor housing near the ignition coil. To access the module, remove the distributor cap, rotor, and if equipped, the dust cover.

TESTING

Make sure to note the position of the ignition wires on the distributor cap. Use a piece of paper and note the wire locations and connections, or carefully mark the wires before removing them. Failure to reinstall the wires correctly could cause expensive component failure.

  1. Remove the distributor cap
  2.  
  3. Remove the black/yellow, blue(1), yellow/green, and the blue(2) wires from the ICM
  4.  
  5. Remove the wires from the ICM
  6.  
  7. With the ignition switch on, check for battery voltage between the black/yellow and ground. If voltage is present, proceed with testing. If no voltage is present check for an open circuit between the wire and the ignition switch.
  8.  
  9. With the ignition switch on, check for battery voltage between the green (white/black on the F22B1 engine) ground. If voltage is present, go to the next step. If no voltage is present, check the ignition coil and the green or white/black wire between the ICM and the coil.
  10.  
  11. Disconnect the electrical multi-connector at the Engine Control Module/Powertrain Control Module ECM/PCM and check for continuity on the yellow/green wire between the multi-connector and the yellow/green wire at the ICM. There should be continuity. If there is no continuity, check for an open circuit in the yellow/green wire circuit. Check for continuity between the yellow/green wire and ground. There should be no continuity. If there is continuity to ground, locate where the yellow/green wire is shorted to ground, and repair. Reconnect the ECM/PCM multi-connector.
  12.  
  13. Detach the connector from the gauge assembly and check for continuity on the blue wire between the ICM and the tachometer. There should be continuity here!
  14.  
  15. If all the test conditions are passed, replace the ICM.

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the distributor cap, ignition rotor, and protective leak cover.
  4.  
  5. Detach the wires from the Integrated Control Module (ICM).
  6.  
  7. Remove the ICM.
  8.  
  9. Installation is the reverse of the removal procedure.
  10.  

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.
