Continuous Test

  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 Engine Running self-tests. Disregard any codes you already repaired. To confirm remaining codes, perform CONTINUOUS MONITOR TEST  .
