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.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
