Continuous Monitor Test
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.
- Engine Running - Activate self-test and perform Engine Running Self-Test. After service codes 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 be entered until self-test is deactivated or engine is turned off.
- Observe volt/ohmmeter while moving, wiggling, or 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 Self-Test to retrieve codes. If any codes are indicated, go to proper test as shown in Continuous Test results. If no codes appear, fault is not in a monitored EEC sensor circuit. EEC functional test is complete. Refer to TEST O - 2.3L HSC, DIAGNOSTICS BY SYMPTOM for additional symptom diagnostic information.

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