Ignition Control Module

  1. Turn ignition off. Disconnect Ignition Control Module (ICM) connector and install Test Harness (49 H018 910). Using a analog volt/ohmmeter, connect (+) lead to ground and (-) lead to single-pin test wire of test harness. See Fig 1 .
    CAUTION: Ensure ohmmeter is installed with (+) lead to ground and (-) lead to single-pin wire of test harness. DO NOT  reverse leads, or damage may result.
  2. Connect Ignitor Checker (49 F018 002) to other lead of test harness and to battery. Set ohmmeter to X1 scale.
  3. Turn ignition on. DO NOT  touch ignitor checker switch SW1. Push up ignitor checker switch SW2 and note ohmmeter reading. Ohmmeter needle should jump to 1/2 of the scale and then return. If ohmmeter does not operate as specified, replace ICM.
