Continuous 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.
  1. Codes shown in this test are intermittent service codes. Unless instructed otherwise, DO NOT  disconnect any sensor with ignition on, or a service code may be stored.
  2. Verify that previous self-tests indicated a pass (code 11). If an On Demand code is detected during this test, repair it first, as some hard failures will set a code in the continuous test.
  3. Perform KEY ON-ENGINE OFF (KOEO) SELF-TEST  . When the first service code is appears, exit self-test by removing jumper wire from self-test input. This clears ECA of all codes stored in continuous memory.
  4. Check your list of Continuous codes that were recorded in Key On-Engine Off and Key On-Engine Running self-tests. Disregard any codes you already repaired. To confirm remaining codes, perform CONTINUOUS MONITOR TEST  .
