Continuous Monitor Test

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1984 Ford RV Cutaway, 1984 Ford Pickup, 1984 Ford Econoline, 1984 Ford Cutaway, and 1984 Ford Club Wagon. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: DO NOT activate Self-Test unless specifically instructed.

This test monitors ECA inputs for shorts and opens. Self-test output will be activated when an intermittent fault is detected. A detected fault is indicated by a 10.5 volt or greater deflection of the volt/ohmmeter. One or both of the following modes may be used to find the intermittent fault:
- Key On-Engine Off - With self-test deactivated, turn ignition switch on.
- Key On-Engine Running - Activate self-test and perform KEY ON-ENGINE RUNNING (KOER) SELF-TEST . After service code output has finished, DO NOT turn engine off or deactivate self-test. About 2 minutes after code 11 has been displayed, Continuous Monitor test will start. It will run until jumper or STAR tester is removed, or engine is turned off.
  NOTE: An alternate method of entering this test with engine running is to enter Key On-Engine Running test, exit, and re-enter KEY ON-ENGINE RUNNING (KOER) SELF-TEST . DO NOT turn engine off.
Observe volt/ohmmeter while moving, wiggling, tapping the system harness, connectors and sensors. If an intermittent condition is created, the monitor will indicate this by storing a service code.
Perform KEY ON-ENGINE OFF (KOEO) SELF-TEST to retrieve codes. If any codes are indicated, go to proper test as shown in CONTINUOUS TEST RESULTS table. If no codes appear, the fault is not in a monitored EEC sensor circuit. EEC testing is complete. Refer to TEST O for additional symptom diagnostic information.

NOTE: Continuous test can only be run once without turning ignition off. DO NOT miss any of the service codes.
