Ignition Control Module Input Test

  1. Turn ignition off. Disconnect distributor 3-pin connector. Turn ignition on. Check for battery voltage between connector terminal No. 2 (Black/Yellow wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, check for an open in Black/Yellow wire between ICM and ignition coil. If wire is okay, check ignition coil. Repair as necessary.
  2. Turn ignition on. Check for battery voltage between distributor 3-pin connector terminal No. 3 (Blue wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, check for an open in Blue wire between ICM and ignition coil. If Blue wire is okay, check ignition coil. Repair as necessary.
  3. Turn ignition switch off. Disconnect PCM 32-pin harness connector. Check for continuity in Yellow/Green wire between PCM harness connector terminal No. 20 and distributor connector terminal No. 1. If continuity exists, go to next step. If continuity does not exist, repair open in Yellow/Green wire between ICM and PCM.
  4. Check for continuity between distributor 3-pin connector terminal No. 1 (Yellow/Green wire) and ground. If continuity does not exist, go to next step. If continuity exists, check for a short to ground in Yellow/Green wire. If wire is okay, ICM may be shorted to ground. Repair as necessary.
  5. Connect PCM 32-pin harness connector and distributor 3-pin connector. If all circuits are okay, replace ICM.
