Continuous Monitor (Wiggle) Test
NOTE:
Make sure Self-Test is deactivated. DO NOT
activate Self-Test unless specifically instructed to do so.
- This test monitors ECA inputs for shorts and opens. Self-Test Output (STO) will be activated each time a fault is detected. If the STO is activated for long enough during Key ON/Engine OFF portion of test, a service code will be stored. During the Engine Running portion of this test, a service code will be stored for each fault.
- A detected fault is indicated by a 10.5 volt or greater deflection on VOM. One or both of the following modes may be used to find the intermittent fault.
- Key ON/Engine OFF: Self-Test deactivated and turn ignition on.
- Engine Running: Activate Self-Test and perform Engine Running 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, wiggle mode will start. The system will remain in wiggle mode until Self-Test is deactivated or engine is turned off.NOTE: An alternate method of entering Continuous Monitor (Wiggle) Test with Engine Running is to start Engine Running Self-Test, exit, and re-enter Engine Running Self-Test without turning engine off.
- Observe VOM while moving, wiggling, and tapping the system harness (in short sections), 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 table. If no codes appear, the fault is not in a monitored EEC sensor circuit. EEC testing is complete. Refer to DIAGNOSIS BY SYMPTOM TEST for additional testing information.
NOTE:
Continuous test can only be run once without turning ignition off. DO NOT
miss any of the service codes.
NOTE:
An alternate method of entering Continuous Monitor (Wiggle) mode with engine running is to start Engine Running TEST, exit, and re-enter Engine Running TEST without turning engine off.
NOTE:
Continuous test can only be run once without turning ignition off. DO NOT
miss any of the service codes.
